Resurrecting the Extinct for Halloween? Why not!

My paleontology obsessed son wants to be New York's state fossil for Halloween. So out came my sketch pad, and Kev and I are now attempting to assemble a prehistoric sea scorpion out of foam floor tiles and fabric... It is a work in progress, and time is flying. Here is what we have done so far:

We still have to make the patterns for the body and tail, cut foam, assemble the segments, cover all the foam with contrasting fabric, detail it with paracord, and make sure it works for standing and sitting... This would be easier if we hadn't left it to the last minute, but hopefully the ghost of Eurypterus remipes will be haunting us come Saturday..
