DOI: 10.1016/j.cretres.2017.09.009
Abstract: Abstract Previously-unknown large scale scrapes attributed to Cretaceous theropod dinosaurs from the Naturita Formation (formerly the Dakota Sandstone) of western Colorado were recently named as Ostendichnus bilobatus and interpreted as evidence of “nest scrape display,”… read more here.

DOI: 10.1080/08912963.2020.1769093
Abstract: ABSTRACT It has long been known that Lower Jurassic theropod track assemblages are dominated by theropod tracks including Eubrontes and Grallator, known from North America since the mid 19th century. It was only comparatively recently… read more here.

Theropod dinosaur facial reconstruction and the importance of soft tissues in paleobiology

DOI: 10.1126/science.abo7877
Abstract: Large theropod dinosaurs are often reconstructed with their marginal dentition exposed because of the enormous size of their teeth and their phylogenetic association to crocodylians. We tested this hypothesis using a multiproxy approach. Regressions of… read more here.

DOI: 10.1371/journal.pone.0262614
Abstract: Spinosaurids are some of the most enigmatic Mesozoic theropod dinosaurs due to their unique adaptations to aquatic environments and their relative scarcity. Their taxonomy has proven to be especially problematic. Recent discoveries from Western Europe… read more here.
