re: #35 EPR-radar
As I recall, fossils of critters eating other critters are incredibly rare in general —- something about dying in such a way as to leave a fossil tends to interfere with proper enjoyment of meals.
The more compelling point is the absence of human bones (or artifacts) in any rock formations that include dinosaur fossils.
I was thinking teeth marks, bone gouges, stuff like that. Stuff you’d expect to see on an animal predated upon by, say, some of the larger raptors.
