Baryonyx the Spinosaur
Baryonyx was a Spinosaur that did not have a sail, but like all Spinosaurs it had a long narrow snout and preyed primarily on fish. We also know that Spinosaurus and its relaations like Baryonyx lived in what is now North Africa in the later Cretacous. Acrocanthosaurus lived in what is now North America in the early Creatceous.
Orca vs Great White Shark
(new drawing)
Another example of Convergent Evolution is sharks and killer whales. Killer whales are also called Orcas. Both sharks and killer whales have similar traits of fins or flippers, a dorsal fin on the back, and a streamlined body. Having those traits is useful in an ocean environment so even though a whale is a mammal and a shark is a cartilaginous fish, they have some similar traits.Orcas or Killer Whales do not like sharks...unless you consider they probably like eating them. Some killer whales will ram and or bite sharks...even the Great White Sharks. The darkened areas of the drawing on the animals should be colored black.

Since Acrocanthosaurus was a Cretaceous Period dinosaur the drawing is at the bottom of the Cretaceous list under Cretaceous animals.
