Diagnosis
ReferenceDiagnosis
H. Riley and S. Stutchbury 1836The genus Thecodontosaurus is likewise founded on the structure of the teeth, and their having been deposited in distinct alveoli.
H. Riley and S. Stutchbury 1840Under these circumstances we consider our animal to be a new genus, and shall found it upon its being a Lizard with alveoli in its jaws.
