Paleontologist Publishes Research on Cannibalism in Dinosaurs
University of Tennessee, Knoxville ^ | May 28, 2020 | Amanda Womac

Researchers surveyed more than 2,000 dinosaur bones from the Jurassic Mygatt-Moore Quarry, a 152-million-year-old fossil deposit in western Colorado, looking for bite marks. They found more than they were expecting.

Big theropod dinosaurs such as Allosaurus and Ceratosaurus ate pretty much everything - including each other...

There were theropod bites on the large-bodied sauropods, whose gigantic bones dominate the assemblage, bites on the heavily armored Mymoorapelta, and lots of bites on theropods too, especially the common remains of Allosaurus. There were hundreds of them, in frequencies far above the norm for dinosaur-dominated fossil sites. Some were on meaty bones like ribs, but researchers discovered others far away from the choicest cuts, on tiny toe bones.

Pulling together all of those data painted a picture of an ecosystem where dinosaur remains laid out on the landscape for months at a time, a stinky prospect, but one that gave a whole succession of predators and scavengers a turn at eating...

Having this many marks on hand let the researchers really dig into details that are sometimes harder to study in smaller collections. For example, theropod teeth are serrated, and every once in a while, that tooth-shape gets reflected in the bite marks they make.

Domenic D'Amore, of Daemen College, previously had figured out a way to translate those striated tooth marks into body size estimates.

Unless they chanced upon the Vegetaritops, a rare type of dino that was meatless and boneless.

When Fred Flintstone ordered his favorite Brontosaurus burgers, did he sometimes ask for the cannibal sandwich version?

Bronts were planteaters so it would have gone down good.

It’s past midnight (yawn) so no more silly thoughts.

I don’t recall a dino that looked like that!!

At least not in my science books.

Maybe some others when I was a kid :)

Sounds like your average Republican congressman.

Otherwise known as a Rino.

I can imagine a Far Side cartoon, with two Allosauruses looking at a carcass of their kind, with one saying to the other, “Yeah, I get your point that yesterday he was our pal Harvey, but today he is dinner. Meat is meat.”

Pigs, chickens and many other meat eating animals today have no problem eating their own dead. To them it is just meat.
