Revealing the diversity of amber source plants from the Early Cretaceous Crato Formation, Brazil [PDF]
BMC Evolutionary Biology, 2020 Background Amber has been reported from the Early Cretaceous Crato Formation, as isolated clasts or within plant tissues. Undescribed cones of uncertain gymnosperm affinity have also been recovered with amber preserved in situ.

Taphonomy of aquatic insects from the Crato Formation Lagerstätte (Aptian, Lower Cretaceous) under an actualistic look. [PDF]
PLoS ONEThe Crato Formation (Aptian, Lower Cretaceous) is a fossiliferous deposit of global significance, representing a lacustrine palaeoenvironment which offers insights into aquatic insect taphonomy. Despite its importance, prior studies lacked an actualistic

New evidence of feathers in the Crato Formation supporting a reappraisal on the presence of Aves [PDF]
Anais da Academia Brasileira de Ciências, 2011 The preservation of delicate structures such as feathers is very rare in the paleontological record, due to the fragility of their components. Fossil feathers have been reported from approximately 50 deposits around the world, from the Late Jurassic to ...

A geochemical model for the preservation of insects in the Crato Formation (Lower Cretaceous) of Brazil [PDF]
Cretaceous Research, 2020 Abstract The Crato Formation Lagerstatte of NE Brazil is well known for the exceptional preservation of its fossil assemblage. A wide variety of plants and animals are preserved with a high degree of fidelity, revealing structures of labile tissues at the micron scale, or even smaller.
