Skeleton of Elasmosaurus, used as the basis for a painting in the 2018 Gallimaufric Science art show: http://cgfx.us/gallhall
Except for the stickers, this is a white on black design.
This dinosaur, known at first only from horribly huge and clawed hands, proved to be an amazing and surprising creature. While it was known to be an ornithomimosaur, the true extent of its bizarreness wasn’t uncovered until D. mirificus was discovered—sans skull—from a dig site in Mongolia in 2009. The looted skull actually turned up later via black market activity, and the fossil was eventually repatriated to Mongolia in 2014.
It is an amazing find, and I was present at the presentation at SVP in 2013.
Theropods are weird.
