During the nineteenth and most of the twentieth century, scientists thought that "Suchosaurus" was probably some kind of obscure Crocodilian. But in 1998, paleontologist Angela Milner was publishing a new description of "Baryonyx", and she realized that the teeth of that spinosaurid dinosaur were extremely similar to those from "Suchosaurus". Later in 2003, she suggested that they could be the same animal. "Suchosaurus" teeth are also very close to the ones from "Cristatusaurus" and "Suchomimus", all this means it has the general features of a member from the family Baryonychinae.
