This is a water penny (Psephenidae) or a type of beetle larva that I found on a rock in a stream near my dad's property in NW Arkansas. When I first found it, I thought I may have found a type of extant trilobite (an ancient vertebrate, common in many fossils).Water Penny in NW Arkansas - YouTube | |
