In Depth

       Astrodon‭ ‬has been a troublesome genus of sauropod dinosaur,‭ ‬partly because of the lack of complete remains for the genus which was initially primarily named from the teeth.‭ ‬Astrodon also has an uncertain relationship with the genus Pleurocoelus,‭ ‬with some authors considering the two to be synonymous,‭ ‬to just some species of Pleurocoelus to be synonymous with Astrodon,‭ ‬to some considering both genera being dubious.
