They were caused, it was believed, by a large hungry theropod spooking and scattering a group of smaller dinosaurs. A new paper – Re-evaluation of the Lark Quarry dinosaur tracksite (late Albian–Cenomanian Winton Formation, central-western Queensland, Australia): no longer a stampede? (pdf, SI) – argues that the site does not represent a stampede at all, but dinosaurs swimming with the current as part of a migration. Somehow, Brian Thomas gets from this research the title “New Dinosaur Tracks Study Suggest Cataclysm.” Continue reading

Cenomanian Last Stand

Not all that far from the Institute’s HQ in Dallas, Texas, is the recently discovered Arlington Archosaur Site (AAS). In February a paper was published in Palaios called Feeding traces and paleobiology of a Cretaceous (Cenomanian) Crocodyliform: Example from the Woodbine formation of Texas. Now, Brian Thomas claims Chewed Dinosaur Bones Fit Flood. We’ll see if they do.

During the Cenomanian the sea level would have been slightly less than this, with the Dallas area being on the coast Continue reading
