Fish fossil decorations
I think they look cool hanging from your wall...hard to come by... but how could you make your own? maybe something about to eat a seaducer or cockroach pattern?

Tale a look at www.fishskulls.com - not fossilized fishes, but skeletons of extant species in display cases or otherwise mounted. They (Rob and Denise Skinner) have made some diorama-type displays that have included the lure/fly used to catch a particular fish.
I could be commisioned to paint something like that. To make one 3D could involve load of hours and get pricey but still doable.
