By the end of the XIXth century a women scientist had the intuition that animal and plants have common ancestors
La Garance voyageuse
Fascinated by the highest massifs, botanists have relatively neglected the
middle altitudes. The Haut-Bugey massif, culminating at 1500 m, is thus relatively unknown,
especially as regards its cryptogamic flora. Here we report new observations of liverworts
(Moerckia flotoviana), mosses (Drepanocladus lycopodioides, D. sendtneri, Hookeria lucens,
O...
Everything that glowsis not necessarily gold, it is sometimes an iridescent blue fruit.
Published in the popularization journal "La Garance voyageuse"
We describe Jurassic fossilized woods from the Gümüşhane and Erzurum regions of Turkey that represent the eastern
Sakarya Zone (eSZ) terrestrial biota. We collected 27 fossil wood fragments in total. All 27 fossil wood specimens rep�resent coniferous trees. We assigned ten specimens to Agathoxylon sp. type 1, fourteen to Agathoxylon sp. type 2, tw...
The Hirmeriellaceae are an extinct family of Mesozoic conifers. Their foliage has been described in the genera Brachyphyllum , Frenelopsis , Pseudofrenelopsis , etc., while their pollen corresponds to the genus Classopollis , the male cones to e.g. Classostrobus or Tomaxellia and the female scales were named Hirmeriella and Paraucaria , for example...
Taphonomy and mineralization of carbonated wood from the Purbeckian facies of l’Usine, Cherves-Richemont
(Charente).
The species Rhytidiadelphus subpinnatus (Lindb.) T.J. Kop. is often confused, especially with R. squarrosus (Hedw.) Warnst. but also sometimes with Loeskobryum brevirostre (Brid.) M.Fleich. ex Broth. Its differential characters are listed from a bibliographical survey and evaluated for plants from mainland France. Discriminating field characters ar...
Organisms that colonize wood are subject to a taphonomic tragedy-the richer and more diverse they become, the greater the deterioration of the host wood and the less likely such communities are to be fossilized. Moreover, palaeobotanical studies of fossil wood usually focus on the plant tissue, neglecting the evidence of parasitic, saproxylic, and...
report on a floristic spring walk of our botany association
Protocedroxylon Gothan and Xenoxylon Gothan are two biogeographically important Mesozoic fossil wood genera. They are the witnesses of a boreal flora whose periodic extensions towards the south characterize Mesozoic climatic oscillations. However, previously documented Arctic records of these taxa are known mostly by poorly dated specimens. A new w...
Analyses of coprolites provide important data on animal feeding and food quality, including information on the taxonomy of the biotope. Knowledge of the diet of extinct animals has implications for our understanding of the evolution of various physiological strategies and feeding adaptations. Here we provide the first description of plant remains p...
Since 1920, the Lyon Linnaean Society has kept a cryptogamic herba-rium which was bequeathed to it in 1906 by Louis Debat. He was a prominent botanist from Lyon, who specialized in bryology and was actively involved in a network of national and international collaborations. After his death, however, he was rarely mentioned and today he is almost fo...
Between 1833 and 1836 in England, then in Prussia and finally in France, young botanists experimented
with making plant fossils to understand better how such fossils could be formed and how to interpret
fossil assemblages. These experiments are described and discussed. Despite these promising beginnings, plant
taphonomy was not really developed as...
Dinosaur bonebeds with amber content, yet scarce, offer a superior wealth and quality of data on ancient terrestrial ecosystems. However, the preserved palaeodiversity and/or taphonomic characteristics of these exceptional localities had hitherto limited their palaeobiological potential. Here, we describe the amber from the Lower Cretaceous dinosau...
Fossil fungi are frequently observed in association with fossil plants in a geological record that dates back over 400 million years to the beginning of the Devonian Period (e.g., Taylor et al., 2015; Krings et al., 2018; Krings and Harper, 2019; Strullu‐Derrien et al., 2014, 2018). Despite this lengthy fossil record, studies of wood colonizing fun...

Premise:
The conifer Geinitzia reichenbachii was a common member of the Cretaceous Laurasian floras. However, the histology of G. reichenbachii leafy axes was never described in detail, and our knowledge of its paleoecology remains very limited. Using new and exquisitely preserved silicified material from the Upper Cretaceous of western France, we...
The paleoxylology of coniferous woods has progressed considerably since Kräusel's last (incomplete) synthesis in 1949. Nomenclatural practice has slowly purged itself of the diagnostic use of etymology. The use of certain new words or phrases has become essential, while other words have been subject to significant semantic drift or unjustified omis...
An amateur bryologist, Louis Debat, was a key figure in Lyons botany at the end of the 19th century. However, he remains relatively unknown, as does his important moss herbarium, preserved at the Société linnéenne de Lyon. The existing brief biographical notes are completed. His practice of bryology is discussed. His relations with the botanists of...
Jean-Jacques Rousseau is known to have recommended the practice of botany, but today he is often considered to be a botanist more exalted than relevant. His letters to Claret de La Tourrette, Gouan and Linné are not, however, of a lesser botanical level than the letters the latter three exchanged. His skills in bryology were exceptional for the tim...
Madame Adélaïsde, the sister of king Louis-Philippe, beside being a flower painter, prepared a herbarium. It contains samples that tell a lot about her life, a herbarium of souvenirs.

bryophytes floristic data
New tracheidoxyls from near the Protophyllocladoxylon leuchsii Kräusel type-locality (El-Kharga, Egypt, Turonian) were xylologically studied. Although most of the samples are not identifiable, one has preserved features, in particular araucarian radial pitting and co-occurrence of podocarpoid and oopores in the cross-fields, which allow assignment...
We report the first Hettangian theropod tracksite (~200 Ma) yielding a rich accumulation of plant remains from the Bleymard Strait (southern France). It constitutes an excellent opportunity to reconstruct lowermost Jurassic ecosystems hosting dinosaurs and which are still poorly documented in this area. Two morphotypes of tridactyl tracks are disti...
The French name of Rubia peregrina is Garance voyageuse, literally "travelling madder". The origin of this curious name is discussed. It has its source in the latin "peregrinus" which designated in Roman time a person who was not Roman, nor a slave, but a free foreigner. The specific epithet "peregrinus" was used by Linné and others for several pla...
Seventy years after its publication Kräusel’s review of fossil conifer woods is still among the most quoted references in this field. Several of his earlier contributions are foundational works, but they have largely been overlooked, which has led to some misinterpretations. We reviewed the taxonomy and nomenclature of the eight genera Kräusel desc...

Female botanical correspondents of Esprit Requien (1788-1851)
The Avignon naturalist Esprit Requien left a collection of nearly 14,000 letters, which he received from more than 2,000 correspondents. Four percent are women. This corpus of women’s letters was studied in the hope of locating little-known female botanists. Twenty-eight w...
In the immediate vicinity of Lyons, the Mont d’Or, a hill of Jurassic limestone topping a Paleozoic basement, rises to 620 m. It was one of the places where French bryology began, around 1790, but has not been the subject of bryological studies for nearly a
century. A catalogue was established, gathering data from the 1790-2017 interval (n = 763) a...
Following the publication of Míguez et al. (2018), concerning the morphological and phylogenetic characteristics of the Carex from the section Rhynchocystis Dumortier and mentioning the possible presence of C. agastachys in Northeastern France, we searched for it throughout 2020. Several stations were found and some of them are syntopic of C. pendu...
A new Cenomanian amber-and plant-bearing deposit has been discovered at Neau, in the Mayenne department (France). The Cenomanian fossiliferous lignites are located in karst filling in a substratum of Cambrian limestones. The amber corresponds mainly to tiny millimetric grains, devoid of arthropod inclusions, but rich in microorganisms, especially t...
Floristique bryologique de la France
This study presents for the f irst time a partial
translation of Clémence Lortet’s manuscript entitled
“Promenades Botaniques” (Botanical Walks), which
had remained unpublished and little known until
recently. Clémence Lortet, born Richard (1772–1835),
was a student and friend of physician and botanist Jean-
Emmanuel Gilibert. Although she shunned...
We investigated the environmental conditions that prevailed in continental ecosystems recorded in sedimentary deposits of Japan during the Cretaceous through the analysis of oxygen and carbon isotope compositions of phosphate (δ¹⁸Op) and apatite-bound carbonate (δ¹⁸Oc and δ¹³Cc) of vertebrate teeth and bones. Local surface water δ¹⁸Ow values were c...
Women were exceptional in scientific societies before 1870. The Société linnéenne de Paris co-opted twenty-five of them, including Clémence Lortet from Lyon. It has been hypothesized that this Linnaean Society was innovative in this respect. But who were the female associate members of the Société linnéenne de Paris? Biographical elements are prese...
The history of botany, as written today, documents few contributions of women before 1890. Botany was, however, much practiced by women from the end of the 18th century onward. In order to understand this discrepancy we explored the practice of floristic studies by women in France in between 1700 and 1870. More than 100 women have produced floristi...
Protocedroxylon from the marine shales of the Upper Jurassic Knoxville Formation, Californa
Jurassic flora of the Tibetan Plateau is poorly known, with limited fossil records. The paleobiogeography of terrestrial biota is, however, one of the major evidences to reconstruct the intricate paleogeography of an area. Well-preserved fossil wood is described from the Middle Jurassic Xiali Formation (Callovian) in the South Qiangtang terrane of...

Life a women who led herbalisations around Paris at turn of the century (circa 1900)
Protophyllocladoxylon Kräusel in Strömer is very probably a taxonomical synonym of Metadopocarpoxylon Edwards. The type of the former is lost. We arrived at the conclusion to propose to conserve Protophyllocladoxylon Kräusel with P. dolianitii Mussa (Bol. Inst. Brasil. Geogr. Estadíst., Serv. Grafico 182: 17. 1958) as its conserved type.
The fossil wood genus Xenoxylon is reported in-situ for the first time in Thailand. It originates from the Indosinian terrane, from the Mesozoic continental redbeds of the Phu Kradung Formation (Khorat Group). Palinspatic reconstruction, palaeobiogeography and correlation with other occurrences of the genus, in southern China as well as in Vietnam,...
Ten embedded fossil logs sampled in situ from the middle Eocene volcano‐sedimentary rocks close to Suffield Point in the Fildes Peninsula, King George Island, Antarctica, are assigned to Protopodocarpoxylon araucarioides Schultze‐Motel ex Vogellehner, Phyllocladoxylon antarcticum Gothan, Agathoxylon antarcticum (Poole & Cantrill) Pujana et al., A....
Les observations sont classées par région et par département
Anthropization has led to severe river incision in several parts of Europe. Biomonitoring is of interest to characterize this incision or, conversely, the effectiveness of ecological restoration. Mosses of the upper flood zone are good candidates for such biomonitoring as they are small organisms with limited water-intake ability. Here we studied t...
North America Jurassic fossil wood record

Fossil Taxaceae are documented for the Cenozoic throughout most of the northern hemisphere, but the pre-Cenozoic history of this group is still poorly known. The fossil wood record is difficult but can shed light on this history. We critically evaluated the fossil woods assigned to Taxaceae and then compared the fossil record of taxaceous woods to...
Brief description of the fossil wood Piceoxylon from the Morrison Formation of central Montana
Avant le grand élan qui vit proliférer les sociétés savantes dans le dernier tiers du XIX e siècle, plusieurs botanistes ont exploré le sud du mas-sif jurassien. D'origines géographiques et sociales diverses, ils ont laissé des traces dispersées, et une histoire de la botanique jurassienne reste à écrire. Quelques-uns de ces botanistes, français, s...
Au cours du XXe siècle, la majorité des sites à plantes fossiles (Hettangien–Sinémurien) de la ville de Mende ont disparu à cause d’une importante urbanisation ou bien sont tombés dans l’oubli. Cet article présente une synthèse des gisements à végétaux fossiles, depuis leur découverte au XIXe siècle jusqu’aux campagnes de prospection récentes. De n...
Les observations sont classées par région et par département et sont présentées de la façon suivante, pour chaque espèce : Nom de commune (code Insee), lieu-dit, précision de localisation (et altitude si précisée), date d'observation, vérification d'identification le cas échéant. Les espèces nouvelles pour le département sont suivies de [Ndep], nou...
A series of bryological specimens was discovered in the Université Lyon-1 herbarium, within the Gandoger collection. It was prepared by Pierre Chabert (1796-1867), a little known amateur botanist from Lyons. After a short biographical sketch, this bryophyte collection, is described. Samples were mostly collected between 1846 and 1855, at a time for...

A new coniferous species Sequoioxylon zhangii sp. nov. is described on the basis of an anatomically well-preserved fossil wood specimen from the Upper Cretaceous in Keshan County of Heilongjiang Province, NE China. S. zhangii is anatomically characterized by abundant axial wood parenchyma, uni-biseriate bordered pits, taxodioid cross-field pits, un...
The Promenades botaniques of Clémence Lortet, born Richard
(1772-1835)
Abstract. – Clémence Lortet, a scientist in the early 19th century, had a profound influence on botany in Lyon. Unfortunately, until now all of her work has remained unpublished, and for more than a century her texts were reputedly lost. Their rediscovery allows us to provide
a...
Three new localities for Neckera menziesii in the French Jura are reported, two for the Ain department, the third for the Jura department. These new localities evidence that the distribution of the species is not discontinuous between the Northern Alps and the northern Jura mountains, as previously hypothesized. Some taxonomical and nomenclatural p...
Si l'existence d'une forme d'intelligence chez le splantes est de plus en plus admise, on s'interroge sur les mécnismes biologiques qui pourraient en être le support
In 1907 the French palaeobotanist Octave Lignier published a study of Jurassic fossil wood that was to become a seminal palaeoxylological work. Although the names he established were often used or recombined and his contribution is still often quoted today, the original material was never re-studied, except for one of the fifteen originally publish...

Over recent decades, diverse structures ascribed to angiosperms, bennettitaleans, conifers, cycads,
ginkgophytes and pteridosperms have been reported from the Cretaceous deposits of the Aquitaine
Basin (southwestern France). However, Albian macrofloras remain uncommon in Aquitania as well
as in France. The clay from the Archingeay-Les Nouillers qua...
A library in Lyon has just be named in honour of a XIXth century female botanist, Clémence Lortet. Her life is briefly described. The role of botany in women access to sciences is discussed.
Nine fossil wood samples from the Mesozoic bedrock and the Quaternary terrace deposits of the Lower Mekong Basin in Southeast Asia including Thailand, Laos, and Cambodia were investigated in order to assist in developing a hypothesis about the Mekong River palaeocourses. Six of the samples were conifers assigned to Agathoxylon sp., and three were d...
New distributional data from France for two European endemic species, Seligeria carniolica and S. irrigata, are provided. The latter is new to France and this discovery significantly extends its current geographical range. The former is red-listed as an endangered endemic species in Europe and for a long time it was known only from some widely dist...
Augustin Augier’s “Arbre botanique” (1801) is one
of the earliest known family tree diagrams to represent
the natural system. As such it is frequently cited in the
literature on historical systematics, where it is generally
framed as a precursor to later, evolutionary trees.
While ignorance concerning the author’s identity long
complicated efforts...
An anonymous Botany text-books published in 1859 in Lyons is assigned to an author, Marie-Thérèse Récy. She was a nun, who teached sciences in girl religious schools for years. Despite what she stated in her book preface, her correspondance evidences that she clearly intended to "clean" botany of sexual or amoral implications. Simple questions and...
Augustin Augier’s “Arbre botanique” (“botanical tree”) (1801), a diagram representing the
natural order of plants in the shape of a family tree, is today a standard reference in histories of
systematics and phylogenetic trees. The previously unidentified author was a nobleman from
Saint-Tropez, a schoolteacher and a priest in the Socie´te´ de l’Ora...
Un moussier anonyme a été repéré dans les collections de la Société linnéenne de Lyon, au sein de collections cryptogamiques. Son étude permet de l’attribuer à Anselme-Benoît de Champagneux (1774-1845). Ces collections contiennent également de nombreuses collectes de Pierre Valuy (1796-1829). Ce sont surtout des lichens, mais Pierre Valuy a aussi r...
The fossil record of Ginkgo leaf and reproductive organs has been well dated to the Mid-Jurassic
(170 Myr). However, the fossil wood record that can safely be assigned to Ginkgoales has not yet been
reported from strata predating the late Early Cretaceous (ca. 100 Myr). Here, we report a new fossil
wood from the Mid-Late Jurassic transition deposit...
The potential of using the latitudinal distributions of fossil wood genera as a proxy for Jurassic terrestrial climate conditions in western Laurasia was tested using a database of 386 entries. The fossil wood genera Brachyoxylon, Protaxodioxylon and Simplicioxylon are southern taxa, which have only occasionally extended north of 45°N (all latitude...
In 1917 the German fossil palaeobotanist Richard Kräusel proposed a new plant family, the Protopinaceae. This family was based on an anatomical feature (mixed type of radial pitting) observed in the secondary xylem of some Mesozoic gymnosperms. Kräusel's hypothesis was that the Protopinaceae had great phylogenetic significance, being an evolutionar...
The Taskomirsay section (South Kazakhstan) is a unique Pliensbachian-Toarcian sequence of lignites, clayey layers and silty-sandstones deposited in a fluvial/lacustrine environment with nearby swampy areas. This period, characterized by a drastic climate change, has been particularly studied in Western Tethyan marine environments, whereas very few...
During the first Korea Antarctic Geological Expedition (KAGEX I, 2013/2014), fossil wood was collected from the Triassic fluvial deposits of the Beacon Supergroup at Skinner Ridge in northern Victoria Land, Antarctica. The material is coalified and partially silicified; most specimens are slightly compressed due to burial compaction. In spite of th...
Deux espèces de mousses sont mentionnées pour la première fois pour le département de l’Ain, Seligeria patula (Lindb.) Lindb. et Seligeria carniolica (Breidl. & Beck) Nyholm. La seconde, endémique européenne rare à l’échelle continentale, y est représentée par ce qui pourrait être la plus nombreuse population connue. Les deux espèces ayant été obse...
In lotic ecosystems, submerged aquatic vegetation has important effects on hydrodynamic and sediment processes. These effects depend on plant morphology and patch structure. This study aimed to test the effect of 2 aquatic plant species on flow and sediment characteristics. For this purpose we measured under natural conditions 3D velocity profiles...
Two moss species are reported for the first time for the Ain department, north-eastern France, Seligeria patula (Lindb.) Lindb. and Seligeria carniolica (Breidl. & Beck) Nyholm. The latter, a European endemic moss, rare at continental scale, was represented by what might be the largest known population. Both species having been observed on marly li...

Despite its limited stratigraphical value, fossil wood has been revealed to be of interest to
characterize the palaeoenvironment evolution during the sedimentation of the Khorat Group. It helps
understand the ecosystems in which the rich Thai Dinosaur faunas evolved. The available Khorat group
