But in the undergrowth were various types of early mammals, as well as tritylodont mammal-like reptiles, lizard-like sphenodonts, and early lissamphibians. Early Jurassic The Early Jurassic epoch (in chronostratigraphy corresponding to the Lower Jurassic series) is the earliest of three epochs of the Jurassic period.

Certain rocks of marine origin of this age in Europe are called "Lias" and that name was used for the period,
