Obligate faunivorous megatheropod size class patterns across the Jurassic-Cretaceous Periods [PDF]
PeerJAllosauroidea, Ceratosauria, Megalosauroidea, Megaraptora, and Tyrannosauroidea are five clades containing obligate faunivorous megatheropods. These clades included apex predators from the Early Jurassic until the end of the Cretaceous Period.

Forelimb reduction and digit loss were evolutionarily decoupled in oviraptorosaurian theropod dinosaurs [PDF]
Royal Society Open ScienceTheropod forelimbs exhibit wide morphological disparity, from the elongated wings of birds to the diminutive arms of T. rex. A wealth of work has sought to understand the evolution of bird flight via arm elongation, but despite widespread occurrences of ...

Enhancing the classification of isolated theropod teeth using machine learning: a comparative study [PDF]
PeerJClassifying objects, such as taxonomic identification of fossils based on morphometric variables, is a time-consuming process. This task is further complicated by intra-class variability, which makes it ideal for automation via machine learning (ML ...

Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago [PDF]
PeerJ, 2020 Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod ...

Rare evidence for ‘gnawing-like’ behavior in a small-bodied theropod dinosaur [PDF]
PeerJ, 2021 Mammalian carnivores show a higher degree of prey bone utilization relative to non-avian theropod dinosaurs, with this major ecological difference reflected in the frequency and morphology of tooth marks in modern and Cenozoic assemblages relative to ...
