Drinker and Oryctodromeus (was Re: Dinosaurs burrowed to keep warm)

Bakker has noted that _Drinker_ lacked ossified tendons, and suggested that that a flexible tail would be useful for a burrow dweller. The taphonomic evidence of burrow-dwelling in _Drinker_ hasn't appeared in print AFAIK - though Bakker has apparentlly mentioned it more than once.


Given the discovery of _Oryctodromeus_, the idea that _Drinker_ was a burrowing "hypsilophodont" will undoubtedly be viewed in a new light_. Drinker_ would extend this behaviour back to the Late Jurassic.
