Elasmosaurus is a very long-necked example of a plesiosaur.
I wanted to take a closer look into it's skeleton, and what we know about it, since it has been hypothesised this could be Nessie.
The same problem exists with the neck though - based on the structure of the vertabrae, it wasn't very flexible. The flippers were strong and paddle-like, and I much prefer the idea that Nessie has more flexibility in her digits.
Plus, that long neck is just a little bit outrageous, isn't it? When you think about other Scottish fauna, it's all pretty compact.
