Wow, it's been absolutely ages since I was on here.
Anyway, I've looked through the recent threads quickly and there doesn't seem to be anything on this. Caught the tail end of an eBay auction via a facebook group and it gives some much needed information regarding the rare late dinosaurs, numbered 223-226. It appears they were released in a pack with a holographic watch. Images attached. The four figures are named as such:
#223 - Stegoceras
#224 - Trilophosaur
#225 - Proganochelys
#226 - Compsognathus corralestris
There's some pretty wonky science on display there with the official descriptions, even considering this was a while ago, but MIMP never cared too much about accuracy with its dinos.
