Typespecies
Megalosaurus (Buckland, 1824) > Megalosaurus bucklandii (Ritgen, 1926) > Scrotum humanum (Brookes, 1763) > Walkersaurus hesperis (Welles, Powell vide Welles & Pickering, 1995)
Megalosaurus > ?Megalosaurus cambrensis (Newton, 1899) = Zanclodon cambrensis [Rhaetian] (Newton, 1899) > Newtonsaurus (Welles vide Welles & Pickering, 1999)
Dentery, referred material including teeth and postcranial remains. Megalosaurus is based on Megalosaurus bucklandii,consisting of an incomplete right dentary from the Bathonian Stonefield Slate, of Stonesfield, England.
Only two of the other species are based on material comparable to the type of Megalosaurus bucklandii. England (Waldman, 1974) consists of parts ot both premaxillae, the right maxilla, the vomer, both dentaries and a surangular from the Bajocian Upper Inferior Oolite of Sherborne, England.
The dentaries of Megalosaurus hesperis resamble those of Megalosaurus bucklandii in six of the nine charecters listed by Madsen, 1976. differ in one (alveoli extending to extreme mesial margin) cannot be determined.
This species is plausibly retained in the genus Megalosaurus. ?Megalosaurus cambrensis (= Zanclodon cambrensis, Newton, 1899) is based on a natural mould of a left dentary from Glamorganshire, Wales. Despite its considerably greater age (Rhaetian), it shows several resamblances to Megalosaurus bucklandii. Megalosaurus seems related to carnosaurs, but futher study is necessary to clarify its relationships.
