Breaking down bones
This may not look like much, but it is in fact a dinosaur backbone! The clues are in the size and depth of the vertebra. An ichthyosaur vertebra is disk-like, a plesiosaur’s is ‘fat’, and a crocodile’s is very indented along the sides. Compare it to other vertebra specimens on the database.
Based on the size and the fact that it was trawled off the sea bed, this specimen is probably from the Kimmeridge Clay off Portland (Upper Jurassic). This is supported by crocodile finds from the sea bed, also likely to be from the Upper Jurassic.
