The fossil record is the primary source of data used to study predator-prey interactions in
deep time and to evaluate key questions regarding the evolutionary and ecological …

Among vertebrate gastrointestinal microbiome studies, complete representation of taxa is
limited, particularly among reptiles. Here, we provide evidence for previously unrecognized …

Existing classifications of snout shape within Crocodylia are supported by functional studies,
but ecological surveys often reveal a higher than expected diversity of prey items within …

Bite marks provide direct evidence for trophic interactions and competition in the fossil
record. However, variations in paleoecological dynamics, such as trophic relationships …

A new Baurusuchidae (Crocodyliformes, Mesoeucrocodylia), Aplestosuchus sordidus, is
described based on a nearly complete skeleton collected in deposits of the Adamantina …

Removal or protection from biostratinomic agents of decomposition, such as predators and
scavengers, is widely seen as a requirement for high-quality preservation of soft tissues in …

Sea turtles are characterized by a wide variety of invertebrate ectoparasites. Few of these
ectoparasites leave a permanent indication of their presence on the skeletal remains of their …

Direct evidence of trophic interactions between extinct species is rarely available in the fossil
record. Here, we describe fish–mammal associations from the middle Eocene of Messel …

Crocodylians are known to consume and modify bones, but actualistic observations of their
bite marks have been limited to forensic case studies and surveys of two taxa: Crocodylus …

A new exceptionally brevirostrine dyrosaurid is described from the middle Palaeocene (58–
60 million years ago) Cerrejón Formation, northeastern Colombia, based on four partial …
