George Albert Boulenger placed Meiolania in Pleurodira and Arthur Smith Woodward officially split the chimeric hypodigm of Megalania into monitor lizard, marsupial and turtle remains, with the name being constrained to the lizard. While this marked the end of Meiolania as a lizard, Woodward agreed with Owen in that the skull from the mainland clearly belonged to an animal related to Meiolania.
