Skeleton of the Marine Reptile Anarosaurus heterodontus (image) University of Bonn Share Print E-Mail Caption CHW 189 from the private collection of Herman Winkelhorst (Netherlands). The neck of the animal is excellently preserved, but the rest is not. One possible explanation may be that this is the result of uneven colonization of the carcass by microorganisms and algae, which created a protective layer especially around the neck.
