Re: Sauroparental care

I'm sure sauropods had reason to dig every now and then.  Pushing up dirt for 
nests, digging for water in a dried up water hole, looking for salt.  IF 
elephants can dig a few feet in search for water, sauropods probably could too. 
 Dig holes, sure, they weighed several tons, I don't think they'd have much of 
a problem moving SOME dirt.  Burrows on the other hand....whole other issue.
