This week I have been very carefully acid preparing this rather nice Saurichthys sp. fossil fish. It is so delicate in preservation that you need a magnifying glass to see its tiny bones.
Here are some images of the fish before preparation (Please click on the images to enlarge)
Species: Saurichthys sp.
Saurichthys means “lizard fish”. This slender fish with a rostrum full of sharp teeth it would have hunted or scavenged other fish. Its streamlined body and rear-mounted symmetrical fins would have made it a powerfull swimmer.
Saurichthys was a relatively common fish in the Triassic, but rare as a fossil. It is found in deposits on all continents except Antarctica.
The jaws were very long, making up a third of the total body length. This example has articulated jaws and skull which includes some very small teeth only just visible to the eye and a beak-like tip to the rostrum.
