A nice example of an ichthyosaur vertebra fossil from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The vertebra is matrix free and measures 17 mm (0.7 inches) across, which is small for this fossil type and so likely from a juvenile ichthyosaur. The bone is well preserved and has been prepared using air abrasive techniques to remove all matrix.
It has good detail in its preservation and a nice dark colour. The neural and rib facets are worn from exposure to the sea.
These fossils were first found by pioneering Victorian fossils hunters like Mary Anning. Ichthyosaur bones are very popular fossils from this location.
Around 198 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.
