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



Delurking for a moment.

Speculation aside, don't count on too many spiny dinosaurs being burrowers. Spines usually only go one way into a hole and backing out isn't very easy. No reverse gear is a bad thing. Thumb spikes, large claws and heavy forearms would have been handy "gardening" tools however. Regarding burrow raiders, build a niche, and they will come but then, the home owners invented the "back door".

Field season is starting on the high plains of Wyoming/Montana. A couple dozen misc. loose teeth came out the other day from a HC microsite in less than an hour. Now I am looking for that elusive burrowing Pachycephalosaur :>

That's a good notion. This thread has really opened up the speculation floodgates! I'm starting to think that maybe *Deinocheirus* could've been a "Dino-burrow-digger-outer" specialist. Is it possible that some Dinosaurs specialized in this way?

Personally, I think that this idea is a better
scenario for _Deinocheirus_ than the previous thoughts
of it being a termite eater. It's hard to imagine a
multi-tonne animal living off of termites, without
wiping out an entire colony everytime it got hungry.

Well, maybe if there were some nasty big termites back
then.

Hmm, if only the graboids from Tremors were real. Then
we might speculate that _Deinocheirus_ was actually a
giant worm hunter. :)
