Here are two really small pes unguals (hoofs or claws depending) from a very small dino perhaps Ornithomimus sp. They are so small it is hard to identify them. They came from my microsite #3 and the scale is an inch square. As you can imagine, attention to detail is required to find this kind of specimen. My process anymore is to pick up any and all fossil material in the field, bag it, take it home and study everything under magnification and good lighting. I avoid throwing nice things away and crushing little things trying to clean off sand with gloves on that way.
