1. The earliest of the Jurassic epochs, followed by the Dogger. The Lias is dated at 208–178 Ma ( Harland et al., 1989), and comprises the Hettangian, Sinemurian, Pliensbachian, and Toarcian Ages.

2. The corresponding European series, roughly contemporaneous with most of the Herangi (New Zealand). Blue-grey shales and muddy limestones are typical of the Lias, with Dactylioceras and Gryphaea among the more important fossils found in the extensive outcrops of England and France.
