We're continuing our efforts to document an describe the fauna from the Harveston neighborhood of Murrieta, a small but diverse collection that appears to be the only Rancholabrean-Age site in Murrieta. The bone shown here is the left lunate of a horse (Equus sp.), with the original bone on the left and a 3D print on the right. The lunate is one of 6 small bones that form the wrist. In horses they are blocky, tightly interlocking bones that can support the stress of holding the weight of a running horse. Unlike primates, which have highly mobile wrists, the horse wrist has essentially no ability to move side-to-side, as is limited to fore-and-aft motion, making it more stable during running.We're planning to scan and print as many of the Harveston bones as possible. The paint job on this print is too dark, so I need to lighten it a bit. O
