Here's another good oldie... A little 'diorama' depicting a plesiosaurus (a marine reptile from the earlier part of the Jurassic) catching a passing dimorphodon (a flying reptile)...
Both reptiles are sculpted out of Sculpey and Milliput over a metal wire frame. The wings of the pterosaur had to be thin, so I cut them out out of a can of Sprite, added the 'fingers' and bones with Milliput and covered them with a thin layer of wood glue.
The nominal wingspan of a dimorphodon was about 1.2 meter. The models were scaled at 1/15. Unfortunately, over my moves from England to the US and back to England, this particular model got lost... and this picture is all I've got left of it...
This model got a first prize in Brussels in 1996.
