the Brachiosauridae. Earlier, Oplosaurus was typically referred to Pelorosaurus following an opinion of Friedrich von Huene in 1909, although Pelorosaurus is based on fragmentary remains that do not include teeth, making it impossible to prove the identity. (See Naish and Martill (2001) for a good review of Oplosaurus and Wealden sauropods in general; here is a more recent informal summation of the state of work.) Given how poor the Pelorosaurus holotype material is, and that it doesn't include teeth, recent reviews have retained Oplosaurus as a potentially valid but poorly known genus. Darren Naish, a British palaeontologist familiar with Wealden sauropods, has suggested informally that the genus may be a turiasaur but also co-authored an article concluding it was a member of the Camarasauridae. In any case, it likely belongs to the more general Macronaria. A 2022 review considered it to be a potential turiasaur, echoing Naish's suggestion. Paleobiology As Naish and Martill point out, the tooth is comparable in size to that of Brachiosaurus, indicating that the owner was a large sauropod; as a possible turiasaur, the size should not change drastically. It would have been a quadrupedal herbivore, possibly around 25 m (82 ft) long.
