The adult holotype of the fossil mayfly Astraeoptera cretacica Brandão et al. 2021 from the
Cretaceous Crato Formation, Brazil, is reviewed and attributed to a new family …

Mass mortality events are unusual in the Crato Formation. Although mayflies' accumulations
have been previously reported from that unit, they lacked crucial stratigraphic data. Here we …

Exceptional preservation through phosphatization is primarily controlled by a reduction in
pH, favoring the precipitation of apatite over that of calcite. Laboratory experiments have …

Abstract The Lontras Shale is a fossil site located in Mafra, Santa Catarina, south of Brazil.
This Late Paleozoic (Pennsilvanian-Cisularian) stratum holds an important place with great …

Species with a xylobiont lifestyle (eg, inside fallen tree trunks) are rarely fossilized because
of their taphonomic peculiarities. Reconstructing the evolutionary history of these lineages is …

Abstract Fossil bonanzas called Konservat Lagerstätten provide geological windows to the
ecology of ancient life communities. These deposits often occur as cluster of fossil localities …

Abstract The Crato Formation (Santana Group, Araripe Basin, Brazil) bears a high
abundance of fossils in exceptional state of preservation, with insects from the order …

The relative completeness of Odonata (dragonflies and damselflies) fossils from the Crato
Formation is investigated and compared to other fossil insect groups from the same …

The digestive tract of insects is morphologically divided into three regions: foregut (or
stomodeum), midgut (ventriculus, or stomach), and hindgut (or proctodeum)(Chapman et al …

Documented here is a variation of the widely used resin transfer technique, allowing for the
preparation of fragile articulated fossil arthropod material preserved in laminated limestone …
