As for your question, I'm pretty sure Mosasaurs had not evolved yet by 95mya when Spinosaurus lived, as they are thought to have evolved during the Turonian, a few million years after Spinosaurus went extinct in the Cenomanian.<br /><br />The known marine reptiles from the time period mostly show small pliosaurs, the last few Icthyosaurs, and a few long-necked plesiosaurs which would probably pose no real threat to Spinosaurus. Their were also some big pliosaurs like Kronosaurus at the time, but these have yet to be found in north Africa, and in fact we think they were deep water specialists, likely not often coming into contact with Spinosaurus, which probably preffered shallow water. So I don't think and marine reptiles would really pose a threat to it; in fact it might be the opposite.<br /><br />As for if anything could threaten it, sauropods can threaten anything they come across, but likely only in defence. That only really leaves big theropods like Carcharodontosaurus and Sauroniops, and it would not often come into contact with these animals. Even when they did, he would pose an equall if not greater threat to them as well. Thus, I really do think that most conflicts would be rare, as they are in most large predatory animals.Tristan Stockhttps://www.blogger.com/profile/08416626700060143529noreply@blogger.comtag:blogger.com,1999:blog-1718421695417441669.post-13127024205322694512013-01-31T17:10:35.909-08:002013-01-31T17:10:35.909-08:00Awsome blog.

If not could something else have threatened it?Davoderhttps://www.blogger.com/profile/11973486457704399919noreply@blogger.com
