Plesiosaur

Make your own plesiosaur

Here is a string of plesiosaur vertebrae, probably found as a scattered or ‘disarticulated’ assemblage of bones. More often than not, dead animals are broken, eaten and smashed up. Perfect specimens are the exception rather than the rule – so palaeontologists have to reassemble the bones in order to understand the animal. 

The extra image shows a vertebra with the neural arch still attached – through which the spinal cord once ran. The arch also provided attachment points for muscles that allowed the animal to flex its back.
