Enzymes used by T. rex to digest raw dinosaur meat


DD1991

Recommended Posts

I know I've been aware of a few papers published several years indicating that T. rex wasn't just a classic scavenger but also an active hunter when it came to preying on herbivorous dinosaurs, and we all know that humans will get food poisoning if they eat raw meat. However, what enzymes did Tyrannosaurus rex have to help it consume the meat of dead individuals of herbivorous dinosaurs like Edmontosaurus annectens and Triceratops?

This is not true. I've eaten steak tartare hundreds of times and never got as much as a belly ache. If the raw meat has bacteria like Salmonella or E.coli then yes you can get sick. Pork and chicken can cause problems, unless the organisms that cause diseases are not present. Then there's no problem. I don't think its a matter of enzymes as much as a matter of immunity. If T-rex was already infested with the same organisms then it would have no problems caused by consuming a few more.

Fossil hunting is easy -- they don't run away when you shoot at them!

Virtually every non-scavenging carnivorous and omnivorous animal other than humans eats flesh raw. The partial answer to your question might be found in more recent animals to discover what enzymes they possess to process raw meat.

You really want to look into the digestive enzymes, look into wolves, bears and vultures. They are all known to eat LONG dead flesh.

Vultures are second to the one and only Tidgy. Who else has the guts to taste something that's been dead for hundreds of millions of years?

@Tidgy's Dad would you agree?

Yup. 

She claims she's helping with prepping, but I'm not so sure. 

Here she is with some Silurian stuff :

and my dog (see under wolves, above).  I think the issue here is that humans have underrated terrible digestive tracts.
