       When Galesaurus was first named by the famous‭ ‬naturalist Richard Owen.‭ ‬He thought that he was naming a new genus of dinosaur,‭ ‬and later when Galesaurus was described in the very first issue of the journal Nature,‭ ‬T.‭ ‬H.‭ ‬Huxley also stated that Galesaurus was a small dinosaur.‭ ‬However,‭ ‬in modern times we are now confident that Galesaurus was not a dinosaur,‭ ‬but actually a cynodont.‭ ‬Galesaurus is often compared to the more famous Thrinaxodon,‭ ‬though there is no doubt that the two genera represent different cynodonts.‭ ‬The most complete specimens of Galesaurus seem to represent juveniles,‭ ‬but when these are scaled through comparison to larger less complete remains of adults,‭ ‬it is clear that Galesaurus was actually fairly large for a cynodont.‭ ‬Still,‭ ‬Galesaurus seems to have been just a bit smaller than Cynognathus,‭ ‬one of the largest cynodonts.
