- noun Plural form of
Sorry, no etymologies found.
(clavicular air sac) and caudal (abdominal air sac) divisions, in basal "tetanurans" (theropod dinosaurs) during the Jurassic.
New theropods - particularly bird-like coelurosaurs (like dromaeosaurs) and big non-coelurosaurian tetanurans (like allosauroids) - make the news all the time, but ornithischians consistently draw the short straw.
I confess to actually liking Oli’s idea, and an interesting consequence of it is that his inclusion of Shuvosaurus within his phylogenetic analysis of Coelophysoidea ‘forced’ Dilophosaurus away from coelophysids and closer to tetanurans.
