Well… I made a loch ness monster stick figure. Does it look accurate? I wanted to make it more serpent and eel-like. The whole plesiosaur design was very boring and basic. Besides. Plesiosaur went extinct. So the loch ness monster would probably either have to be a new species that is adapted to living in loch ness. They would have to be smaller and slimmer. And probably had dark murky skin.

(Not really prehestoric but it’s still an ancient animal)
