Re-evaluation of the Bahariya Formation carcharodontosaurid (Dinosauria: Theropoda) and its implications for allosauroid phylogeny. [PDF]
PLoS OneThe first partial skeleton of a carcharodontosaurid theropod was described from the Egyptian Bahariya Oasis by Ernst Stromer in 1931. Stromer referred the specimen to the species Megalosaurus saharicus, originally described on the basis of isolated teeth

Allometric growth in the frontals of the Mongolian theropod dinosaur Tarbosaurus bataar [PDF]
Acta Palaeontologica Polonica, 2022 Tarbosaurus bataar is a sister taxon of the well-studied theropod dinosaur Tyrannosaurus rex, and numerous fossils of this tyrannosaurid have been discovered in the Upper Cretaceous Nemegt Formation of Mongolia. Although specimens of different sizes of

New data on the distal tarsals in Ornithomimidae [PDF]
Acta Palaeontologica Polonica, 2021 The ankle in non-avian theropod dinosaurs consists of the astragalus and calcaneum proximally and a distal series of tarsal bones capping the metatarsals.

Why tyrannosaurid forelimbs were so short: An integrative hypothesis [PDF]
Acta Palaeontologica Polonica, 2022 The unusually shortened limbs of giant theropods, including abelisaurids, carcharodontosaurids, and derived tyrannosauroids such as Tyrannosaurus rex have long been an object of wonder, speculation, and even derision on the part of both ...

Iridescent plumage in a juvenile dromaeosaurid theropod dinosaur
Acta Palaeontologica Polonica, 2023 Colour reconstructions have provided new insights into the lives of dinosaurs and other extinct animals, by predicting colouration patterns from fossilised pigment-bearing organelles called melanosomes.

A new two-fingered dinosaur sheds light on the radiation of Oviraptorosauria [PDF]
Royal Society Open Science, 2020 Late Cretaceous trends in Asian dinosaur diversity are poorly understood, but recent discoveries have documented a radiation of oviraptorosaur theropods in China and Mongolia.

Royal Society Open Science, 2021 Locomotor energetics are an important determinant of an animal's ecological niche. It is commonly assumed that animals minimize locomotor energy expenditure by selecting gait kinematics tuned to the natural frequencies of relevant body parts.
