Teeth lie at the interface between an animal and its environment and, with some exceptions,
act as a major component of resource procurement through food acquisition and processing …

Mosasaurs are marine squamates with a 32.5 million-year history from their appearance at
98 Ma to their extinction at the K–Pg boundary (65.5 Ma). Using a database of 43 generic …

Abstract Mosasaurs (Squamata, Mosasauridae) were large aquatic reptiles from the Late
Cretaceous that filled a range of ecological niches within marine ecosystems. The type …

Amniotes have been a major component of marine trophic chains from the beginning of the
Triassic to present day, with hundreds of species. However, inferences of their (palaeo) …

Organisms that are durophagous, hard prey consumers, have a diversity of tooth forms. To
determine why we see this variation, we tested whether some tooth forms break shells better …

Mosasaurid squamates are the most numerically abundant, and taxonomically/ecologically
diverse clade of marine amniotes represented in the Maastrichtian Phosphates of Morocco …

Mollusc and brachiopod shells have served as biological armour for hundreds of millions of
years. Studying shell strength in compression experiments can provide insights into …

Machimosaurus was a large-bodied durophagous/chelonivorous genus of teleosaurid
crocodylomorph that lived in shallow marine and brackish ecosystems during the Late …

Cretaceous limestones near Maastricht (SE Netherlands) have been quarried at least since
Roman times. In the late eighteenth century, scientific interest developed in their macrofossil …

The shapes of vertebrate teeth are often used as hallmarks of diet. Here, however, we
demonstrate evidence of frequent piscivory by cartilaginous fishes with pebble-like teeth that …
