Inhabiting South America during the Late Cretaceous Period, the enormous sauropod Argentinosaurus is the heaviest known terrestrial animal and, according to BBC, also has the record for being the longest land animal. It was, of course, discovered in Argentina, and would have been a contemporary of Giganotosaurus.

Allosaurus was a thirty or so foot long carnivorous dinosaur from the Late Jurassic Period. Discovered in the Morrison Formation of Colorado, Montana, New Mexico, Oklahoma, South Dakota, Utah, and Wyoming, this dinosaur (or one quite like it) was also likely found in the Tendaguru Beds of Tanzania. The Cleveland-Lloyd Dinosaur Quarry near Price, Utah holds the remains of more than forty individual Allosaurus bones.

Spinosaurus is an enormous carnivorous dinosaur that we have talked about on multiple occasions, both in our "Biggest Carnivorous Dinosaur" trilogy of posts awhile back, but also in Mr. Church's Top Ten list. Spinosaurus, despite the fact that it is easily the largest known carnivorous dinosaur, with an estimated length of almost sixty feet, did not eat meat like the other enormous dinosaurs: instead, Spinosaurus was a piscivore, or a fish eater. This giant creature lived in Africa during the Cretaceous Period.
Parasaurolophus is another one of those dinosaurs that overlaps from Mr. Church's list to my own. Parasaurolophus is certainly an interesting creature! A member of the hadrosaurs, or duck-billed dinosaurs, Parasaurolophus, as Mr. Church discussed, is the only dinosaur I know of where paleontologists know with a high degree of accuracy what they sounded like. The large crest on the back of the head of Parasaurolophus is full of hollow tubing, similar in shape and structure to the trombone, as well as similar in sound, too. Unfortunately, I could not find a sound file or video of the call, so if anyone has access to a scientifically reconstructed call, let me know!
