liassic การใช้

At Plaidy a patch of clay with Liassic fossils occurs.
It belongs to the Lower Liassic in age and is probably confined to Lyme Regis, Dorsetshire.
On the south side deposits of carbonates and clastic sediments formed a shelf in shallow water during late Triassic and Liassic times.
The type specimen for " T . trigonodon " is an almost complete skeleton from the upper Liassic of Banz, Germany of the Lower Toarcian.
The Blue Lias is the lowest of the Liassic stratum and where it is visible on the coast near Lyme Regis is layered with hard limestone and oil-rich shale.
