Natural History Docent: “A guy asked us ‘If I had a time machine, and managed to kill and cook a T-Rex, what would it have tasted like?’ and every paleontologist on staff deciced to take him seriously. They did research to learn about fat distribution, and read up on culinary science to learn what flavors meat, even did chemical analysis on the bones. They concluded that it’d be Tough (no evidence of juicy fat pockets), bitter (carnivores tend to taste foul) and would probably kill him, because heavy metals travel up the food chain and T-Rex accumulated a lot of the cadmium that was in the dirt in the late cretaceous. Wrote him a letter with our findings and he sent us back a drawing of him and his buddies cooking a T-Rex over a fire and all of them throwing up and dying, and it’s my favorite drawing in the whole world.”

For some reason, my memory was really confident that this was a question on Randall Munroe's what if? blog, but I couldn't find it. I even checked the copy I have of the first what if? book to be sure it wasn't in there lol
