Try the Reptile section.

If it was me ... either a skin mount, or custom mold and cast it. Depends on my mood!

Ahhh ... most likely mold and cast it! Pose it up real well in a bed of Hi-Fiber, mold with silicone in however many sections required, plaster mother mold, cast it in Smooth-On SC-305, install eyes, prep and paint. There you go!
