New record of Abelisauroid Theropods from the Bauru group (upper cretaceous), São Paulo State, Brazil [PDF]
, 2014 Isolated bones of abelisauroid theropods from the Bauru Group (Late Cretaceous, Brazil), are described. They correspond to three individuals represented by fused ischia and part of the ilium, a partial axis, and a right fi bula, respectively. The fossils

Cancellous bone and theropod dinosaur locomotion. Part II—a new approach to inferring posture and locomotor biomechanics in extinct tetrapod vertebrates [PDF]
, 2018 This paper is the second of a three-part series that investigates the architecture of cancellous bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct non-avian ...

Putative avian teeth from the Late Cretaceous of Alberta, Canada, are more likely from crocodilians.
PLoS ONE, 2023 Isolated teeth, previously referred to Aves, are more common than other bird fossils from the Late Cretaceous of Alberta. However, there are no known morphological synapomorphies that distinguish isolated bird teeth, and features of these teeth are ...

Resting Orientations of Dinosaur Scapulae and Forelimbs: A Numerical Analysis, with Implications for Reconstructions and Museum Mounts. [PDF]
PLoS ONE, 2015 The inclination of the scapular blade and the resting pose of the forelimb in dinosaurs differ among reconstructions and among skeletal mounts. For most dinosaurian taxa, no attempt has previously been made to quantify the correct resting positions of ...

Theropod-bird link reconsidered [PDF]
Nature, 1998 Norell et al.1 describe a Velociraptor ‘wishbone’ which they interpret as a new piece of evidence for the theropod origin of birds. The bone fits a pattern of furcula-like structures that have been discovered in certain late Cretaceous theropods, including Oviraptor, Ingenia and possibly others2, some of which possess clavicles — usually not fused. But
