The original spelling for the type species of Megalosaurus Buckland 1824
was Megalosaurus bucklandii Mantell 1827, a nomen nudum next spelled
bucklandi by von Meyer 1832. Megalosaurus appeared as a Parkinson 1822 nomen nudum
(without a species name), and the binomial name Megalosaurus conybeari Ritgen
1826 is a nomen nudum/nomen oblitum. As the concept of a type species, with
diagnosis and hypodigm, was relatively unknown then, most of the taxonomy dating
from the period has, it goes without saying, been the subject of considerable
revision.
I am in the process of revising Sam Welles's revisions and descriptions
of all of the Jurassic European theropods (with line drawings and photographs
of virtually all of the known specimens). Megalosaurus, based upon a
disarticulated yet associated skeleton (and not, as some have erroneously claimed, a
partial dentary), is clearly diagnosable.
