In this paper, we describe a dinosaur track assemblage from an Upper Triassic fluvial succession at the Lisowice-Lipie Śląskie site in Silesia, southe…

High-resolution computed tomography is used to reconstruct and analyse fossils of the herbivorous tritylodontid Polistodon and a newly named morganucodontid species called Camurocondylus, providing key insights into the evolution of the mammalian jaw joint.

Mississippian insect records are extremely rare. Formally, winged insects occur only at two sites from the Serpukhovian: Delitzsch in Germany, with one species of Palaeodictyoptera; and Guandacol 1 i...

Megaraptoran theropod dinosaur anatomy and evolution is unclear due to the fragmentary nature of most available fossils. Here the authors report a well-preserved, late surviving megaraptoran from Argentina that clarifies our understanding of the morphology of this group and potentially provides insights into its diet and feeding strategies.

Dinosaurs promoted open habitats in the Late Cretaceous, and their extinction could have led to a radical reorganization of the landscape and ecosystem structure at the beginning of the Paleogene, acc...
