Some people think that this South american relative known as Oxalaia, is bigger than Spino. Unfotuneatly, this overgrown spino has only a few teeth, a bit of a nose, and the spines discovered. Spino was an average 45-55 feet long. Some think Oxalaia was the same size, and some think it was nearly 55-65 feet long. Is this true?
There is'nt really much that we could tell from just old bones. If the animal was alive today, we'd be able to see if it was bigger than spinosaurus or not. But for now, it is but a mystery.
There really isn't any dinosaur that is bigger than a Spinosaurus. It's the biggest carnivore of all time, and in my opinion better than a T-Rex (with its stupid arms).
