Long considered (and still, by some) to belong to Centrosaurus, there are various
differences between the skull shapes. One of the theories is that Monoclonius represents
a subadult Centrosaurus, while the counter comments are that the skulls are more or less
the same size, so Monoclonius cannot be a young Centrosaurus.
Feel free to comment any mistakes i might have done on the skull restoration.
