A fundamental question in biology is whether phenotypes can be predicted by ecological or
genomic rules. At least five cases of convergent evolution of the crab‐like body plan (with a …

A combined biostratigraphic and palaeoecological study of foraminifera, ostracodes and
microfacies was carried out on the Aptian in the Sítio Sobradinho section of the Araripe …

The aim of this study was to produce an integrative analysis of macroinvertebrates
(decapods, gastropods, and bivalves) and microfossils collected in the Romualdo …

Abstract The Santana Group, consisting of the Barbalha, Crato, Ipubi and Romualdo
formations, records the post-rift sequence of the Gondwana break-up in the Araripe Basin …

Absolute dating of sedimentary rocks and fossils from the Mesozoic are still rare, mainly due
to the difficulties arising from diagenetic changes. Diagenesis promotes changes in the …

Direct evidence of paleo-parasitism in crustaceans is very scarce. Epicaridean isopods are
obligatory parasites of crustaceans, including decapods such as crabs, shrimps, and …

Amber fossils provide snapshots of the anatomy, biology, and ecology of extinct organisms
that are otherwise inaccessible. The best-known fossils in amber are terrestrial arthropods …

Evolutionary origins of novel forms are often obscure because early and transitional fossils
tend to be rare, poorly preserved, or lack proper phylogenetic contexts. We describe a new …

The goal of this study is to investigate the Aptian–lower Albian microfossil association
present in the Romualdo Formation, Araripe Basin, Pernambuco State, northeastern Brazil …

A systematic study is made of Early Cretaceous (late Aptian/earlyAlbian) ostracod
assemblages from the Santo Antônio section. This section is characterized by sediment …
