@lance-comfort This is another ID I’m going to struggle with. I can say with almost 100% certainty that it is a proximal phalanx, and not a metacarpal. That said, it take us into a similar vein of issues as the rib fragment…phalanges can also be tricky to identify. My first thought is that it sort of looks like it’s from an artiodactyl. A few more photos of other angles might help us to get closer, though!
