Species

Polycotylus ischiadicus was made the type species of the new genus Thalassiosaurus by Welles (1943), while the name Plesiosauus ichthyospondylus is a nomen nudum because Seeley (1869) provided a type specimen but did not accompany it with a description and indicated that his taxa were never intended to take taxonomic precedence.

True or false

Is it true that it is also found in Russia and Australia or is this a mistake?
