A new angiosperm from the Crato Formation (Araripe Basin, Brazil) and comments on the Early Cretaceous Monocotyledons [PDF]
Anais da Academia Brasileira de Ciências, 2014 The Crato Formation paleoflora is one of the few equatorial floras of the Early Cretaceous. It is diverse, with many angiosperms, especially representatives of the clades magnoliids, monocotyledons and eudicots, which confirms the assumption that ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil). [PDF]
Anat Rec (Hoboken)Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

UPLC-QTOF-MS/MS and Antifungal Activity of a Fraction Enriched in Saponins From Sarcomphalus joazeiro Against Candida spp. [PDF]
Biomed ChromatogrABSTRACT The development of antifungal resistance is a complex process that involves the interaction between hosts, drugs, and microbial factors, all of which contribute to therapeutic ineffectiveness. For this reason, studies on natural products as possible therapeutic alternatives are increasingly necessary in order to gain a better understanding of ...

A new genus of fossil frog (Anura) from lower Cretaceous deposits in South America
Anais da Academia Brasileira de Ciências, 2021 The frog clade Neobatrachia or “advanced frogs” represents more than 95% of the diversity within Anura. The neobatrachian fossil record is incomplete due to the small size and fragile nature of their bones but provides some clues on the time and rate of ...
