RE: T. REX THE HUNTER(finding cover) LONG
FWIT (Is that appropriate for "For what it's worth?")
I offer a piece of info to add to your thinking about carnivore hunting:
One of the sites we have uncovered at our digs on the Warm Springs Ranch
appears to be a feeding site. This is in the Morrison Formation (Jurassic)
in north-central Wyoming.
* Lots of footprints squished over each other as if the area were soft and
there was a lot of activity, not just a "passing by" track.
* Lots of teeth (allosaur, in this case) , both what appear to be adult and
juvenile. Allosaurs shed teeth fairly consistently as they ate; the
presence of several sizes of teeth indicates presence of several sizes/ages
of the critter.
* Bones - lots of bones, different from the bones in our other dig sites in
this manner: the bones in the other dig sites where we are fairly certain
bones were deposited/washed by water/river/streams are smooth, rounded. The
bones in the feeding site are sharply broken, cracked, gnawed, with lots of
teeth marks. Because of this difference in the bone, it is apparent that
these were reasonably fresh kills, not stuff that had been lying around a
long time on a flood plain.
* But -- and here's the real point I guess -- they are not the bones of one
animal, but of several types (i.e.., stegosaur plates, diplodocus tail,
etc.) and they are all PARTS that could easily have been transported -- a
leg torn off and returned to the feeding site, an arm, etc.
So it appears to us that the allosaurs (at least) were simply tearing off
part of the kill and carting that to a spot where perhaps the young waited
-- not dragging an entire animal.
Whether one critter was left to watch over the kill while the other carried
parts back to the site, who knows? Or whether she (I suspect it was a she,
if not a they) took what they could get and left the rest for the
camp-followers, we can't say.
The site is on the side of the mountain, and when the weather clears, we'll
be working further back into the mountain, where there is clear indication
of more remains.
