A flash flood could certainly have drowned the animals in the first
place and deposited bodies together (or a short disance apart) in mud
without scattering their remains.
And we need not necessarily look to flood to determine why the animals
died together. Perhaps some volcanic event led to mass death -- and
these dromaeosaurs were scavenging a carcass when lethal gases
I assume that the predation hypothesis suggests a struggle to kill the
Tenontosaur, with several Deinonychus dying in the process.
Isn't the patent absurdity of this obvious?
How often to pack-hunting vertebrates attack a prey animal and lose
*three* of their number in the process? They may lose one but that
would be a fluke. In the *highly* unlikely event that they accidentally
attack an animal that is too tough for them (hunting vertebrates tend to
very carefully choose their prey), they'd certainly back away and cut
their losses. The object of the game is to survive, not just to kill.
Pack hunters just do not attack an animal that will kill multiple pack
This hypothesis seems to remove dinosaurs from the realm of reality and
surrender them to the fantasy of antediluvian "savage monsters" which we
now know that they certainly were not.
So unless the Tenontosaur went postal (upset with comments about his
"big tail") and started hunting Deinonychus, the whole scenario just
seems counterintuitive to me.
The only other rational explanation I can see is that there was a fight
at the found carcass (theropods certainly seem to have been rough with
each other) leading to the deaths of certain animals.
