Camptosaurus

Another super-later entry from the Oxford Museum back catalogue, this is Camptosaurus. I’m not one who is deeply into my ornithischian systematics, but as far as I’m aware this is fairly uncontroversially close to Dryosaurus and Dysolotosaurus and the like and thus in the dryosaur clade that is basal to the iguanodontians and hadrosaurs.

I’d much rather comment on the mount which is superb. It’s a shame about the wooden batten in the cabinet, but well, that’s part of the furniture. But the suspension of pieces in space like this without an obvious big metal armature is really nice to see. OK so yeah, the specimen is largely visible from only one side, but this offset by the superb way it’s put up and I really like this.

    I also like mounting the specimens with drawings of the missing elements rather than casts or sculptings.

    It emphasizes to visitors the fragmentary nature of our current understanding and therefore why future discoveries may result in significant changes in our current beliefs.

    The idea that a “theory” is constantly changing — the esence of scientific inquiry — is sometimes alien to lay-people who see it as a failing of science.

    That is a reason “creationism” — which never changes therefore providing certainty — finds an audience.

    Isn’t it the holotype of Cumnoria?

      Well yes. I’d got the ID from the exhibit though which listed it as Camptosaurus. When I don’t know any better I go with how it’s presented.

    Good to see Cumnoria prestwichii, which is based upon a rather nice skeleton, gaining some internet presence. However, it has never been considered a dryosaurid, but instead has long been placed in the genus Camptosaurus (Lydekker 1889; Gilmore 1909; Galton and Powell 1980; Norman 2004). My phylogenetic analysis found Cumnoria prestwichii to be more derived than Camptosaurus dispar (McDonald 2011), hence my reinstatement of the genus Cumnoria (Seeley 1888) for what was originally Iguanodon prestwichii (Hulke 1880).
