A nice example of a bone block with bones from an ichthyosaur from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.
The piece or Jurassic shale matrix measures 135 mm (5.3 inches) across and contains several bones from a juvenile ichthyosaur. There are two vertebrae and one piece of rib in the matrix. The vertebrae have been worn by the sea and one has some damage from exposure to the elements before it was found.
It is had to find blocks with multiple bones in like this one, and each shows a snapshot of the seafloor in the early Jurassic. The bones are well preserved and have been prepared using air abrasive techniques.
The fossil weighs 1060 grams.
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.
