Sidewalks are not a trivial topic. They are a fundamental element of streets, the main public spaces in urban environments. In modern cities, paving materials are mostly artificial. In Portugal, stone-paved sidewalks are still prevalent and quite characteristic. Walking down a street, you do not need to lift your eyes off the ground to know you are...

A geodiversidade é a variedade natural de aspectos geológicos, geomorfológicos e dos solos que constituem o planeta Terra, incluindo as suas associações, relações, propriedades e sistemas. Em articulação com a biodiversidade, é fundamental para a integração dos aspectos abióticos e bióticos que constituem a natureza. A geodiversidade apresenta vari...

The cancellarid genus Sveltia Jousseaume, 1887, is widespread in western European and North African Neogene marine fossil assemblages. In Pliocene deposits it is commonly represented by Sveltia varicosa (Brocchi, 1814), which until recently was considered a widely distributed taxon in the Mediterranean Sea and adjacent Atlantic faunas. A recent rev...

This project examines the role of tropical storms in the northeast Atlantic Ocean related to the post-mortem deposition of rhodoliths in coastal settings during Neogene to Holocene time with primary emphasis on Sal Island in the Cabo Verde Archipelago located 600 km off the coast of Senegal in northwest Africa. Fossil rhodoliths from 10 to 15 cm in...

The worldwide study of the geological record of the Last Interglacial is key to reconstruct the climatic and oceanographic conditions during that time interval. Here we present preliminary results of a comprehensive field analysis of one of the most extensive and least studied Quaternary fossiliferous sequences in Cabo Verde attributed to the Last...

The preliminary study of the Cirripedia of the Pliocene of Vale de Freixo revealed four species of balanids previously unknown from the Portuguese Neogene, one of which with open nomenclature: Austromegabalanus (Notomegabalanus) decorus (Darwin), Balanus crenatus Bruguière, Concavus concavus (Bronn), Zulloconcavus sp. Two wall fragments collected s...

Upper Miocene to Pleistocene assemblages of northwestern France are commonly grouped as Redonian faunas. Although earlier authors recognized their diverse and heterochronic character, Redonian assemblages continued to be monographed as if they were homogeneous, hindering understanding. Here we critically review the lower Pliocene (Zanclean) Assembl...

Between Lagos and Albufeira, the Algarve coast of southern Portugal is marked by outcrops of the lower Miocene Lagos-Portimão Formation (LPF) consisting of yellow sandstone and coarse skeletal-rhodolithic limestone. This contribution focuses on the rhodoliths, their paleoecology, taphonomy, and biological composition, in the Lagos Biocalcarenite, t...

The concept of geodiversity is extensively used in geoconservation and geoheritage contexts. Its cultural value, i.e. the value attributed by society to aspects of the abiotic natural environment because of its historical, emotional or community importance, is widely recognised. One important manifestation of the cultural value of geodiversity is t...

The first report of the Hirnantia high-latitude peri-Gondwanan Fauna from Portugal (Upper Ordovician, Ribeira do Braçal Formation) is presented here. The described macroassemblages are fairly diverse containing fossils of brachiopods, trilobites, echinoderms, machaeridians, and ostracodes. Among the brachiopods, the most abundant is Mirorthis mira...

The Ordovician sequence of the Portalegre Syncline lacks a detailed lithostratigrapic study, hampered by structural complexity and intense deformation. In this study, a lithostratigraphic model is presented, supported by new biostratigraphical data. A Late Ordovician age for the upper part of the sequence is confirmed and unpublished data from Nery...

The author analyses the implications of formalising the use of the term “Anthropocene” to refer to Archaeology in its relationship with Palaeontology. He discusses and contextualises the theoretical construction of this chronostratigraphic unit – which is still informal, as well as insufficiently characterised and delimited – within the wider debat...

Bioturbation structures from Ponta das Bicudas in Santiago Island, Cape Verde Archipelagoare located in coarse-grained biocalcirudite sandwiched between basaltic lavas of the Upper Pleistocene Assomada Formation.

The careers of Charles Darwin (1809–1882) and James Dwight Dana (1813–1895) are intimately linked to circumnavigations of the globe with the British mapping expedition on the H.M.S. Beagle (1831–1836) under Captain Robert FitzRoy and the United States Exploring Expedition (1838–1842) under Lieutenant Charles Wilkes. The former expedition mainly sur...

The illaenid trilobite Vysocania is widely represented in the Upper Ordovician of the Czech Republic, Portugal and Spain, and is one of the most characteristic taxa in the high-latitude peri-Gondwana palaeobiogeographical region to which it is endemic. Three species of the genus that were formerly assigned to Stenopareia and Zetillaenus, from the C...

A new upper Katian (Kralodvorian Regional Stage) benthic association from the Riba de Cima Member of the Ferradosa Formation, Portugal, is described. It is dominated by bryozoans and echinoderms but brachiopods and trilobites are also present. More than 20 species of brachiopods, nine of trilobites and eight of echinoderms have been identified in t...

Distribution of living rhodoliths in the Macaronesian realm is limited by extensive rocky shores and narrow insular shelves that rapidly drop off beyond the 50-m isobath. Wind and wave erosion is most intense on north and northeast-facing shores due to the prevailing northeasterly trade winds over much of the region. Southern shores offer more shel...

Here we report and describe for the first time the Foliomena Fauna fossil record from Portugal (Kralodvorian, upper Katian). This deep-water brachiopod association originates from the uppermost beds of the Porto de Santa Anna Formation (uppermost Katian), cropping out in several localities of the Portuguese Buçaco-Penacova region (Central Iberian Z...

One key element defining the appearance of Lisbon is the whitish Cretaceous fossiliferous limestone locally known as “liós.” The liós is abundantly used as ornamental stone in Lisbon’s monuments and buildings. Ceramic tiles are also paramount in creating Lisbon’s character. Their ubiquitous presence, their colourful patterns and even the unique way...

Coral-dwelling pyrgomatid barnacles (subfamily Ceratoconchinae) were widely dispersed throughout the Paratethys and Mediterranean seas as well as the Atlantic Ocean during the Neogene, but today are limited to the Western Atlantic. Herein, the paleobiogeographic origin and dispersal of the genus Ceratoconcha is studied based on a combination of fie...

The current debate on the "Anthropocene" was born within the Environmental and the Earth Sciences. The concept of "Anthropocene", both for the best and for the worst, by fostering the idea that humans have become the dominant force shaping our planet, is very popular among the general public. This awareness of the impact of mankind on planet Earth...

A questão, significativa de uma perspectiva geológica e ambiental e, para o melhor e para o pior, extremamente apelativa do ponto de vista da cultura popular, tem suscitado neste início de século debates acesos que já extravasaram em muito o domínio mais estrito das ciências geológicas e ambientais. A discussão sobre o impacte da Humanidade sobre o...

The fossiliferous beds cropping out at the classical Vinha de Leira Má locality (Buçaco), consisting of approximately 10-15 metres of volcaniclastic sediments, are included in the Leira Má Member of the Upper Ordovician Porto de Santa Anna Fm. In this work we provide evidence supporting an upper Berounian age for the fossil assemblage of this local...

Today, more people live in urban areas than in rural ones. Hence, there is a strong case for using urban geodiversity, rocks, fossils, landforms, etc., in outdoor geological educational and geoawareness activities. On the other hand, the present-day world is deeply influenced by technology. Smartphones, GPS-capable devices, tablet computers, and In...

According to UN data, today, the majority of the world's population lives in cities. City people, typically, are sedentary, highly dependent on their urban environment, and easily loose touch with the natural world beyond city limits. Hence, urban pedestrian tours aimed at the observation of palaeontological and geological aspects are paramount for...

The study of bioeroded rocky paleoshores applied to the practical resolution of paleontological and geological issues, already showed its usefulness. The study of the geological record of this kind of paleoenvironments in Portugal, with particular interest in Neogene occurrences, has resulted in a better understanding of the geological history of t...

Maio is a volcanic island with an area of 269 km2 in the Cape Verde archipelago off the west coast of Africa. Although considered a leeward island, it absorbs NE trade winds that typically register 5 to 6 on the Beaufort Scale (moderate to fresh breeze). The trade winds produce ocean swells commonly 3.5 m in height that scour the island’s north coa...

Today, the marine gastropod genus Cittarium is present only in the West Indies faunas, represented by a single species C. pica, also known from the Pleistocene of Bermuda. Herein Cittarium praepica n. sp. is described from the Upper Miocene Cercado Formation of the Dominican Republic. This is the oldest fossil record for the genus in the eastern Tr...

The presence of Spiricella unguiculus Rang, 1828, is reported from the Pliocene of the Estepona Basin (Spain). This species, both fossil and present-day, is always extremely rare. So far, no occurrences of the animal have been reported, only the shells are known. It is possible that its unusually long stratigraphical longevity may be artificial and...

Until now, the buccinid genus Chauvetia was considered of European or West African origin, and is still endemic to these areas today. This paper describes the oldest representative of the genus, Chauvetia inopinata nov. sp., from the upper Burdigalian-lower Langhian transition Cantaure Formation of Venezuela. This surprising record suggests a New W...
