Plate with 12 Ichthyosaur Tail Vertebra Plus Belemnite
The plate itself is 9x7 inches in length and the vertebra average about 1 inch wide. The preservation is very nice and it's been cleaned using air abrasives with no restoration. It comes from the Posidonia Shale Formation formation in Germany which is approximately 183 million years old (Early Jurassic)
Ichthyosaurs ("Fish Lizard") was a giant marine reptile which thrived from much of the Mesozoic era. They evolved in the mid Triassic from a group of unidentified land reptiles which transition back into the water. This line evolved in parallel to the ancestors of todays dolphins and whales, something known as convergent evolution.
Belemnites were an extinct order of cephalopods (think shelled squid) that lived during the Mesozoic era.
