Ryosuke Motani and Lars Schmitz - with the University of California, Davis - found structural evidence in the skulls of 33 so-called archosaurs, land-based dinosaurs and flying pterosaurs.

The finding has implications for our understanding of ancient life-forms, because alligators and birds share a distant common ancestor. mass extinction event that occurred 251 million years ago - called "the Great Dying" - a group of creatures called archosaurs (Greek for "ruling lizards") became the dominant land animals on Earth.

I stayed in (too weary for eyes on me, and the autumn sky) and read "Superiority, Competition, and Opportunism in the Evolutionary Radiation of Dinosaurs" (Science, 12 September 2008), which examines the question of just how dinosaurs managed to come out of the Triassic so much better off than their crurotarsan contemporaries (non-dinosaurian archosaurs, including phytosaurs, aetosaurs, 'rauisuchians,' etc.).

Heilmann argued that birds could not have descended from dinosaurs predominantly because dinosaurs lacked clavicles, or so he thought, and he therefore favoured the idea that birds originated from the so-called 'pseudosuchians': primitive archosaurs that were also thought ancestral to dinosaurs and crocodilians.

The take-home message from such a conflict is that in addition to critically scrutinizing current theories on how mammals and archosaurs supposedly coexisted we should also be carefully examining what we do and do not know about the vertebrate sequence.

The exposures in the park are Late Triassic in age and contain early dinosaurs, labyrinthodont amphibians, and many crocodile-line archosaurs and well as numerous plants and freshwater invertebrates.
