The first results of the systematic study based on disarticulated ossicles of the ophiuroids and crinoids from the Miocene of the Lower Tagus Basin are presented. In this stage of the study, the ophiuroid ossicles can only be assigned to the Class Ophiuroidea; the crinoid ossicles, reported for the first time in the Miocene of Portugal, are assigned to the Order Comatulida, which only includes unstalked crinoids.
Bulls and horses, the central theme of this Congress, belong to two orders of mammals: respectively Artiodactyls and Perissodactyls. 4e presence of these two groups abundantly represented in Neogene sedimentary deposits of the Intermediate and Distal sectors of Lower Tagus basin it’s very well known since very soon, existing a vast collection collected under the work of the National Geological Service, and kept in the Geological Museum of LNEG. In this work, which aims to make known the abundance and diversity of mammalian fauna of the mentioned groups present in the Neogene deposits of the regions of Ribatejo and Lisbon, we refer the main deposits of mammals of the concerned regions, its geographical location, the main known representatives of these two groups, and their geological context and stratigraphic Framework in the region. We will also mention some of tafonomic aspects associated with the 2ndings, as well the context in which occurred the discoveries, in particular those of Lisbon, associated with the exploitation of geological features of the city.

Equinoides endocíclicos(Echinodermata:Echinoidea)Cretáceo Superior da Formação Jandaíra, Bacia Potiguar, Nordeste do Brasil-Equinoides endocyclic(Echinodermata:Echinoidea) of the Upper Cretaceous in the Formation Jandaíra, Potiguar Basin, Northeast BrazilFoi realizada a revisão sistemática dos equinoides pertencentes às ordens Phymosomatoida e Arbacioida da Formação Jandaíra, Bacia Potiguar provenientes de três localidades fossilíferas. Para a ordem Phymosomatoida foram revisadas as espécies Rosadosoma riograndensis (Maury, 1925) e Phymosoma major Coquand,1862, e para a ordem Arbacioida, Goniopygus sp. As espécies Cyphosoma majus (Coquand, 1862) e Phymosoma tinocoi (Santos, 1960) foram consideradas sinônimas de Phymosoma major. Goniopygus sp. foi transferida para Goniopygus durandi Perón & Gauthier, 1881. A partir dos dados biométricos dos exemplares de Rosadosoma riograndensis e Phymosoma major foi verificado que o diâmetro da carapaça influencia de forma significativa a altura das carapaças, assim como o diâmetro do perístoma. Além disso, foram observados diferentes estágios ontogenéticos nos exemplares analisados. Na Formação Jandaíra, os equinoides endocíclicos tiveram seu registro do Turoniano ao Santoniano.

O Cretaceo foi um periodo de muitas mudancas na superficie terrestre que contribuiram para o desenvolvimento de uma rica biodiversidade de organismos. A Bacia Potiguar esta situada na costa Nordeste do Brasil, ocupando parte setentrional dos estados do Rio Grande do Norte e do Ceara. E uma bacia formada a partir do rift ocorrido no periodo Cretaceo durante a instalacao do Oceano Atlântico Sul. Os representantes da classe Echinoidea estao presentes na Formacao Jandaira de forma abundante chegando a formar extensos bancos compostos por suas carapacas. Este estudo teve como principal objetivo fazer a revisao sistematica das especies de equinoides da Formacao Jandaira, da Bacia Potiguar. Nesse trabalho foram analisados, descritos e ilustrados 223 exemplares de equinoides provenientes de seis localidades na Formacao Jandaira. Esses exemplares foram obtidos a partir de coletas realizadas em 2003 e 2011 e depositados no acervo da colecao da Fundacao Paleontologica Phoenix (FPH). Foram iden...
SUMMARY. The Quercus suber woodlands of the ceno-anthropozoic Tagus river basin. Portugal. The analysis of the lithological formations on the Tagus river basin, with ages between Miocene and Pleistocene, allows the understanding of the mosaic of two potential vegetation communities, respectively, Oleo sylvestris-Quercetum suberis and Asparago aphylli-Quercetum suberis. The grain- size analysis, the cohesion of particles and the effect of the anthropic actions on the lithological formations are the major factors that justify the mosaic of the two potential cork tree woodlands and the respective dynamic stages. Human activities over sandy formations and conglomerates, promote liberation and accumulation of sand particles. This process induces psammophilous species to colonize, surrogating primitive potential vegetation (Asparago aphylli-Quercetum suberis) with the cork tree psammophilous series (Oleo sylvestris-Quercetum suberis).
