Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
