Permian Vertebrates

A skull of the Lower Permian temnospondyl, Trimerorhachis, and a near-complete Upper Permian "parareptile", Barasaurus in the order Procolophonomorpha. Only the distal parts of the tail and two limbs extended beyond the limits of the concretion. In situ gastroliths can be seen in the animal's abdomen.

The German Xenacanthus is the classic spine-headed freshwater shark of the period.
