The event organized by various public and private institutions took place in the city of Diamante (Entre Ríos, Argentina). From the LPP and IBIOGEM laboratories, we participated there on behalf of CICYTTP. Daniel Ghilini (Conicet doctoral fellow – APN 2022), Verónica Ma...
Article
A new genus and species of microconchid tubeworm, Aculeiconchus sandbergi n. gen. n. sp., is described from the Givetian (Devonian) Maywood Formation of Cottonwood Canyon, Wyoming, USA. It possesses unique hollow spines of various lengths on the tube underside, a position previously undocumented for these fossils. Like some cyclostome bryozoans pos...
Article
Incised valley-fill deposits of the Middle Devonian Maywood Formation at Cottonwood Canyon, Wyoming, USA, contains a significant palynological record. Twenty-six palynotaxa were recovered, of which 21 species have wide paleogeographical distribution. The presence of the microspores Samarisporites triangulatus and Contagisporites optivus, as well as...

Chapter
Macrofloristic or microfloristic zonation of MesozoicMesozoic successions, with or without independent marine–biostratigraphic age constraints, is extensively utilized in sedimentary basin analyses worldwide. However, precise macrofloral or palynological demarcation of the non-marine MesozoicMesozoic successions remains elusive in India. This uncer...
Article
The palynology of the Jagüel Formation at Cerro Azul locality Río Negro province; in the Neuquén Basin, was studied. The distribution of palynomorphs (spores, pollen grains, chlorophytes, and miscellaneous forms) across the outcrops allowed the definition of three palynological associations: A1 (upper Maastrichtian), A2 and A3 (Danian). The palynol...

Faunipollenites Bharadwaj is considered a junior synonym of Protohaploxypinus Samoilovich emend. Morbey. However, Indian workers claim it is a valid genus due to a poorly defined corpus and absence of folds in distal attachment. In India, a standard method is applied including the oxidization with HNO3 more than 48 hours (+10’ of KOH). We analyze t...

Palynological investigation carried on the samples from the Unit 1 of the Sappington Formation (Upper Famennian, Montana, USA) reveals a presence of rich phytoplankton and microflora assemblages. The presence of spheroidal vesicles approx. 20 μm in diameter having a rigid smooth wall and frequently arranged in clusters connected by an external coat...
Article
We present new data on the Vichigasta Carboniferous paleovalley, a glacial trough crucial to understand the type of glaciation that affected western Gondwana during the Late Paleozoic Ice Age (LPIA). The filling of this paleovalley starts soon after the mid-Carboniferous glacial peak. Stage I represents pro-glacial lacustrine deposits with outwash,...

The book “Atlas of pollen and plants used by bees” was prepared with great care with the data of researchers from Argentina, Brazil, Canada, and Colombia, who are collaborators of RCPol - Online Pollen Catalogs Network. RCPol was conducted during the development of the project entitled “Study of bee flora and pollen grains for the insertion of data...
Article
During the Late Palaeozoic, the Gondwana supercontinent formed an extensive Southern Hemisphere landmass that was affected by multiple glacial episodes, known collectively as the Late Palaeozoic Ice Age (LPIA). This resulted in the deposition of glacial, periglacial and deglacial sediments over much of the supercontinent. The Mississippian to early...

Vertebrate faunas of the Mesopotamian region in Argentina provided palaeoclimatic and palaeoenvironmental information from the Pleistocene. Samples collected into a carapace of the turtle Chelonoidis lutzae and associated sediments obtained from the Toropí/Yupoí Formation (Arroyo Toropí, Bella Vista) palynologically studied for the first time. The...

For the first time, Late Devonian palynofacies analyses of the Lower Sappington shale units U1A─D was carried out at Peak 9559 (Sacajawea) and Ainger Lake in the Bridger Range of Montana. Diagnostic spore species Apiculiretusispora verrucosa, Diducites mucronatus and D. versabilis allowed the correlation of our U1A-D with the European Late Famennia...

New biostratigraphic ages and the stratigraphic revision of a c. 4 km thick succession of Lower and Upper Carboniferous beds, exposed in the Del Salto creek, in the western Precordillera (San Juan, Argentina) are presented. Detailed mapping and analysis of the vertical and lateral variations of the sedimentary systems of the three units we are rede...

The palynology (150 species of pollen grains, 43 species of spores, eight species of dinoflagellate cysts, five genera of algae, two genera of fungal spores, foraminiferal linings and copepod eggs) of the Neogene succession in the Marañon basin, north Peru, was thoroughly investigated for the first time from six industrial wells (Arabela-1X, Maynas...

The morphology and structure of megaspores assigned to Lagenoisporites magnus from the Toregua Formation, Retama Group, mid-upper Tournaisian of Bolivia were studied. The analysis was performed with light, fluorescence and scanning electron microscopy. Megaspores were laterally compressed and presented a spherical body with a proximal gula, of the...

Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vas...

This work documents for the first time a palynological assemblage in the Rajmahal Basin, tentatively considered probable youngest Late Pennsylvanian assemblage, which was hitherto considered early Permian. The palynocomposition consists of 39 species (5 spores, 25 monosaccate, 5 bisaccate- 3 non striate and 2 striate grains, scarce Navifusa sp., sc...

Article
This investigation documents the first palynoassemblage spanning the Middle-Upper Devonian from four outcropping sections located in northwestern Argentina. The recovered material includes fairly well-preserved palynomorphs, both from marine and continental origin, including acritarchs, prasinophytes, cryptospores, spores and chlorophytes. In two o...

Cratonic depositional systems in the Central Montana Trough involve the Devonian--Carboniferous boundary (DCB), and reflect both subtle regional epeirogeny and significant global glacioeustatic controls. A palynologic analysis of the upper Three Forks, Sappington and lower Lodgepole formations was carried out at the classic Logan Gulch location in...

Largely terrestrial Pennsylvanian strata (Macharetí and Mandiyutí groups) in Bolivia and northern Argentina contain a brief marine incursion. Dominated by glacio-fluvial and glacial diamictites, much of the thick succession is peri-glacial in origin and deposited within a basin with paleohighs. In southernmost Bolivia (Balapuca section), new discov...

Paleoecological information about the 600-year span from the end of the Warm Period, through the Little Ice Age, into the modern period is scarce in the central Appalachians and no comparison exists with similar settings in the southern hemisphere.
