Portugal has a rich fossil record both on the continent and in the Azores islands (Santa Maria). For decades, researchers have found thousands of fossils and identified hundreds of species from major taxonomic groups. The present work focuses on analyzing the scientific literature on fossils of Chondrichthyes collected in fossiliferous deposits of...

Knowing what has been previously done before starting a new study is of primary importance when conducting novel scientific research. Portugal has more than two centuries of research in Paleontology; however, this information is currently scattered. The present project aims to compile all fossil occurrences reported in the country by creating an oc...

These are the proceedings of the Paleo Spring Meeting.

This second migration report highlights some statistics regarding the 10,000 fossil occurrences currently available in the new database version.

3º volume do Tylostoma, o boletim informativo da Sociedade Portuguesa de Paleontologia. The 3rd volume of Tylostoma, the Portuguese Society of Paleontology newsletter.

In this first project report, we will focus on the data migration process, bringing back some of the old updates' statistics and sharing some new information now available to us in the new system.

The “Portuguese Fossil Database” is a project which aims to compensate for an existing gap in the availability and analysis of the Portuguese paleontological data as a whole. The present abstract shows the preliminary data related with taxonomic diversity, which was acquired after almost two years of work and the analysis of more than 500 peer-revi...

With more than two centuries of palaeontology research focused on material found in Portugal, and a growing research community dedicated to the subject, the absence of platforms dedicated to gathering, organizing and sharing the published data continues to pose a problem. The Portuguese Fossil Database was created two years ago, in May 2021, as a s...

Before the appearance of the digital tools necessary for online science communication to become the norm, researchers primarily relied upon printed scientific journals to spread science novelties. Older publications are thereby the starting point for any bibliographic search and, therefore, a key element to the Portuguese Fossil Database. Thus we n...

The Lusitanian Basin is located in the western part of Portugal (mainland), which was formed during the opening of the North Atlantic Ocean in the beginning of the Mesozoic Era. The geological cross section of this basin is reached approximately 5-6 km in thickness and consists of Upper Triassic to Lower Cretaceous sedimentary deposits. The infill...

A prospecção e estudo do registo geológico português providencia fósseis há já quase 3 séculos. Dos grandes fémures de dinossauro aos micropólenes, a diversidade de espécies supera quaisquer expectativas que poderíamos ter quando nos propusemos a realizar uma base de dados da Paleontologia Portuguesa em Maio de 2021, mas a informação está dispersa...

With the acquisition of additional material and in the light of new knowledge and methodologies, a more profound and more complex reassessment of the fossil diversity of Brielas selachians was carried out. In the present study, modern maceration, morphometric and geochemical methodologies are explored, as complements to the traditional methodologie...

Whenever a new study begins, it is essential to know what has been done previously. Although Portugal has more than two centuries of research on Palaeontology, not many publications feature bibliographic reviews on the subject. The current project aims to disclose all fossil occurrences reported in the country by compiling the available data and cr...

A maioria dos estudos realizados em Paleoictiologia focados na diversidade de peixes cartilagíneos, Chondrichthyes, são caracterizados pela ausência de espécimes fósseis completos. Devido ao seu esqueleto único entre os vertebrados, exemplares completos e articulados de seláceos são preservados apenas em condições de fossilização muito particulares...

The fossiliferous marine Miocene sediments of the Lower Tagus Basin (Portugal) present a great diversity of Chondrichthyes forms. The current study focuses on the fossil sharks from the Langhian Vc unit of the Brielas section, located in the Setúbal Peninsula. A total of 384 isolated fossil teeth were analysed and ascribed to 17 species from the Or...

This book is the Abstract Volume of the Paleo Fall Meeting 2019 congress.

A work dedicated to describe and classify a sample of shark teeth from Bentiaba, Angola, and to continue the research done so far on the fossil species present in this geological site, by adding up to the already available knowledge.

Bibliographic review of the fossil Chondrichthyes species found until the current year in Portugal.

Comparative anatomy is a fundamental Biology branch, that assists systematic researchers in the classification of organisms (recent and fossils) based upon the similarities and differences of their morphological characters. However, it is conditioned by the access to distinctive reference collections, mostly osteological, and the existence of the s...

The production of high volumes of scientific data is a standard output of any research nowadays. In Paleontology, if we multiply it by several research teams of different branches, such as the vertebrate, invertebrate, micropaleontology, paleobotany and so many others, the amount of information gathered is immense. It generates not only management...

Portugal has a relatively small territory, but with a high diversity fossil record. Including both mainland and insular accounts, researchers have found throughout the years, thousands of fossils and identified hundreds of species, some even new to science. This taxonomic diversity expands throughout most known major fossil groups and ranges from t...

The Langhian Vc unit of Brielas section (Caparica road, Almada), in the marine Miocene of the Lower Tagus Basin (West Portugal), is rich in batoid species. In this study, batoids are represented by 149 isolated fossil teeth and a single fossil dental plate collected from a bulk sample of washed and sorted sediment. A total of 12 species belonging t...

Abstract: Chondrichthyes are known to have a great diversity of dental morphologies, both in fossil and recent organisms, primarily due to their diet, sexual dimorphism, and ontogeny. Usually found isolated, the teeth of cartilaginous fishes are the basis for the separation and cataloguing process of chondrichthyan species. Throughout the developme...

No lugar de Brielas, Península de Setúbal, Bacia do Baixo Tejo, afloram sedimentos correlacionáveis com a unidade Vc de Lisboa, correspondentes ao Langhiano (aproximadamente 14 ± 0,4 Ma, pela datação 87Sr/86Sr da concha de um pectinídeo). Os sedimentos recolhidos anteriormente nesta unidade revelam uma elevada riqueza específica de Chondrichthyes e...

Selachiens of Middle Miocene, Baixo Tejo (Brielas, Portugal) The site at Brielas, near Costa de Caparica (Middle Miocene), has high species richness represented in this study by 671 isolated teeth, 11 dermal denticles and 4 sting fragments. Forty six taxa were identified and described, belonging to the following orders: Carcharhiniformes, Myliobati...
