       During its taxonomic history Gwyneddosaurus has been identified as being several different types of animals,‭ ‬from a theropod dinosaur to a protosaur.‭ ‬Today however the wider consensus is that Gwyneddosaurus was a relative to the better known Tanystropheus,‭ ‬and marine reptile noted for having a particularly long neck.‭ ‬The type specimen of Gwyneddosaurus however is of a vastly smaller individual than what we usually see in Tanystropheus.‭ ‬There is speculation that Gwyneddosaurus may be synonymous with the genus Tanytrachelos,‭ ‬however if this were the case it would be preferable to preserve Tanytrachelos as a valid name since this genus is based upon vastly superior fossil remains than Gwyneddosaurus,‭ ‬which may have fossils from a coelacanth fish accidentally confused with it.
