Dinosaur size

Paleontologist sometimes study dinosaur size. They range from the small bee hummimg bird to the giants such as Argentinosaurus and Alamosaurus. Dinosaur records can sometimes change. For example Tyrannosaurus was said to be the largest dinosaur until larger theropods began to be found. The records also do not include all largest dinosaurs. For example Stupendicus was said to be very large dinosaur but it is not in the records.
