Sauropods stomping theropods, redux

, 2011
A month ago, I posted an article containing all the examples known to me of that sadly neglected palaeo-art theme, Sauropods Stomping Theropods: Mark Hallet’s <em> Jobaria </em> squishing <em> Afrovenator </em> , Luis Rey’s <em> Astrodon </em> biting/carrying a raptor, Mark Witton’s <em> Camarasaurus </em>

Cellular preservation of musculoskeletal specializations in the Cretaceous bird Confuciusornis

Nature Communications, 2017
Birds have a more crouched posture compared to their theropod dinosaur ancestors. Here, Jiang and colleagues describe a lower hindlimb of the Early Cretaceous birdConfuciusorniswith soft tissues apparently preserved even as molecules, indicating a ...

Theropod dinosaurs from Argentina

, 2016
Theropoda includes all the dinosaurs more closely related to birds than to sauropodomorphs (long-necked dinosaurs) and ornithischians (bird-hipped dinosaurs). The oldest members of the group are early Late Triassic in age, and non-avian theropods flourished during the rest of the Mesozoic until they vanished in the Cretaceous-Palaeogene mass extinction.

Morphological disparity and structural performance of the dromaeosaurid skull informs ecology and evolutionary history

BMC Ecology and Evolution
Non-avialan theropod dinosaurs had diverse ecologies and varied skull morphologies. Previous studies of theropod cranial morphology mostly focused on higher-level taxa or characteristics associated with herbivory.
