First elasmosaurid plesiosaur from Montana announced

Elasmosaurid plesiosaurs are notorious for ‘losing their heads’. In fossil plesiosaur skeletons the skull is frequently missing, unfortunate because this is such a vital part of the anatomy for understanding the relationships and biology of the animal. This fact makes the discovery of a new elasmosaurid skull, the first ever from the state of Montana, all the more significant.

Research suggests long-necked plesiosaurs fed on seabed

The long neck of the plesiosaur is a mysterious adaptation for which many hypotheses have been proposed. The most recent suggestion comes from Dr Leslie Noè of the University of Cambridge . After examining the neck vertebrae of the long-necked plesiosaur Muraenosaurus, whose name translates as ‘Moray eel lizard’, Dr Noè concluded that the natural position of the neck was a downwards curve towards the seabed.
