The evolution of life on Earth is characterized by gradual variations and discontinuities. Both led to the current biodiversity. The continuities are shown in the various existing species of organisms that appeared millions of years ago and the great mass extinctions appear as testimony to the discontinuities that shaped evolution and allowed the emergence of new species. One of the most enlightening examples is the extinction of non-avian dinosaurs, which allowed the development of mammals and the consequent appearance of our species. We are currently concerned about climate variability and biodiversity adding the extinction of various species. Are these changes the result of geological and biological evolution? Or are they also a consequence of human activities?
This meeting aims to discuss and debate the importance of the continuities and discontinuities of the fossil record, also discussing whether we are facing the evidence of a new discontinuity.
Image of the encounter: Ginkgo biloba leaves, the example of a biological continuity. The oldest fossils of this tree date back 270 million years, which means it existed before the first dinosaurs and long before the first humans. It is, therefore, a plant that time has not changed.
Meeting logo image: stylization of a nautiloid shell. Nautiloids belong to a group of sea molluscs, the Cephalopods. Nautiloids, dating from the early Paleozoic era, still have living forms, the Nautilda, which may have appeared in the Upper Triassic, some 215 million years ago, having survived two mass extinctions, the one at the end of the Triassic and the one at the end of the Cretaceous, being thus good representatives of the fossil record.
Poster image: leaves of Ginkgo biloba. Coming from China, Ginkgo biloba is the sole living representative of a plant taxonomic order named Ginkgoales, that appeared in the Permian. However, only in the Lower Jurassic does the gender Ginkgo seem to have appeared. The species Ginkgo biloba is the only present representative of a long tree lineage, that may have appeared already in the Quaternary, probably evolving from similar earlier forms, such as Gingko adiantoides, which survived in Europe until ca. 2,5 million years ago.

Entidade organizadora:Centro Português de Geo-História e Pré-História (CPGP) is a non-profit research and scientific investigation association. It was founded on February 15, 1995 and in July 2017 it was recognized by the Portuguese Government as a public benefit entity. Its activities can be divided into two main types of activities:
Field research work in the field of paleontology and archaeology, office work and laboratory research on the materials collected during the field campaigns, collaboration in research work carried out by other institutions that fall within the CPGP study area, development of partnerships through the signing of protocols with other organizations.
Exhibitions and conferences in schools, museums and other public places, as well as publications on topics related to their field of study and research.
Co-organizing entity / Place of the Meeting:Biblioteca Nacional de Portugal
The Biblioteca Nacional de Portugal (BNP) is situated in Campo Grande, close to Entre Campos, in the city of Lisbon. Holding the largest bibliographic heritage in Portugal, its mission is to gather, protect and make available the Portuguese documentary heritage. Its collection exceeds three million documents. Over the course of its two hundred years, it has gathered its collection either through a legal deposit or through the acquisition of works of recognized bibliographic or cultural value.
The BNP is considered as a national bibliographic information centre and cooperates with similar national and foreign institutions through the National Bibliographic Database (PORBASE), due to its information network, which allows each user access to the services of this Library without space limit. The National Library is one of the founding entities of the service The European Library, which aims to provide Internet access to the European cultural heritage.
Address: Biblioteca Nacional de Portugal. Campo Grande, 83 - 1749-081 Lisboa. Portugal
