Work-in-progress of Polycotylus, a late Cretaceous plesiosaur.
This year a specimen was described with viviparous fetae inside her - which could be potential evidence of mothering!
ůSo here she is with her beebees. :3
Oh, I used a variation on Wilhelm's fluke reconstruction, too - just for lulz.
Not horribly accurate, I just wanted to draw some baby plesiosaurs.
