Re: Tyrannosaurs gorged on the young

The article indicated this was determined from coprolites.
How can one determine which dino a coprolite came from?
While the size and bone pieces in the coprolite indicate a large predator as
already discussed here, another interesting point made by Dr. Chin was the
presence of muscle tissue in the coprolite. Karen Chin thought this might
suggest a number of possibilities, including illness, quick digestion (aka,
quick metabolic rate), or gorging. She pointed out that dogs will commonly
have undigested flesh in their feces, depending on how much they gorge
themselves or what kind of meals they eat.
Of course, we cannot know exactly which dinosaur egested (technical word for
"pooped") the coprolite, but its size and age would make it a likely
candidate from the bowels of a T. rex.
