Unenlagiid theropods: are they members of the Dromaeosauridae (Theropoda, Maniraptora)?
Anais da Academia Brasileira de Ciências, 2011 In the present paper we analyze the phylogenetic position of the derived Gondwanan theropod clade Unenlagiidae. Although this group has been frequently considered as deeply nested within Deinonychosauria and Dromaeosauridae, most of the features ...

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>

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.
