Scales of Lepidotus gigas, Agas.
a. two of the scales detached.
The fossil fish resemble generically those of the oolite, belonging all, according to M. Agassiz, to extinct genera, and differing remarkably from the ichthyolites of the Cretaceous period. Among them is a species of Lepidotus (L. gigas, Agas.) ([fig. 306.]), which is found in the lias of England, France, and Germany.[275-A] This genus was before mentioned ([p. 229.]) as occurring in the Wealden, and is supposed to have frequented both rivers and coasts. The teeth of a species of Acrodus, also, are very abundant in the lias ([fig. 307.]).
