Amphibian

Jig-saw skull The amphibians from the Triassic rocks of East Devon were once thought to be crocodiles due to the similarity to their armoured scutes (body plates). However, this is a single skull plate which would have fitted together with several other plates, like a jig-saw, to form a solid skull. The worn edge provides…

Triassic reptile

This is the lower jaw of a reptile, Kapes bentoni, only known from the East Devon coast. Kapes is a tortoise-like reptile and as such, it lies within the ‘anapsid’ group of reptiles. These are considered to be the most primitive forms of reptiles.

The flint itself originated from the spines of sponges that became buried in the ooze at the bottom of the chalk sea. Later, ground water percolating through the chalk dissolved the spines and carried the…

Bivalve shell Trace Fossil Burrow

Cretaceous shipworm – with no ships to bore into! Here is a really unusual fossil – the boring made by a bivalve shell. Modern shipworms are also bivalves, not worms. Today they bore into wooden piers, docks and ships. We don’t know what the Cretaceous shipworms bored into, but it is most likely that it…

Ammonite

This block of oolitic limestone also contains belemnites and pecten shells (scallops). The name oolite refers to the tiny egg-like structures that make up the rock. These are grains of sand or shell fragments that were rolled around in a warm sea gathering layer upon layer of calcium. The name oolite is derived from the…

Ichthyosaur

This is a strangely preserved ichthyosaur skull in which the upper jaw has broken away revealing the teeth still largely in place. The left eye socket is quite well preserved, as is the overall symmetry or shape of the skull.
