The latest prehistoric find on this stretch of coast is a print from the sauropod family of dinosaurs - including the brachiosaurus and diplodocus, distinctive by their very long necks, long tails, big body and small head.

It simply may have been too risky, they said, for a predator - even one weighing multiple tons - to try to bring down an adult sauropod perhaps five to 10 times more massive like Brachiosaurus.

Bites were detected on sauropod bones belonging to Camarasaurus, Galeamopus and Suuwassea as well as bones probably but not definitively belonging to Diplodocus, Apatosaurus and Brachiosaurus.

People who answer T. Rex seem fundamentally different than those who prefer a herbivore like a brachiosaurus.

Rather, dinosaurs like Brachiosaurus got so big because they had systems of air sacs in their bodies that allowed them to breathe more efficiently while also making their skeletons lighter; laying eggs removed some of the constraints around carrying big babies to term, like elephants and giraffes have to contend with.
