Here's some old Cambrian fan art! <3 (Is it fan art or paleoart when you're doodling prehistoric critters just because you love them? I guess it's both.)
I liked how the Alalcomenaeus turned out so much that I made it into a painting, although I was working from some poorly preserved fossils so there's a lot wrong with the anatomy (missing great appendages and median eyes, telson is the wrong shape entirely, etc.). This is an extremely speculative reconstruction that definitely crosses the line into fanciful, but I just really liked the idea of a megacheiran with an iridescent carapace and brine shrimp-like feathery gills. You never know, it could have happened.
