A set of three fossils, all found by Matthew Rhodes. In the top right is a dark, roughly rectangular tooth with the dark enamel facing up; this is a rodent molar. In the bottom middle is a long, curved tooth with dark enamel on the front end and lighter brown dentine on the back; this is a rodent incisor. On the middle right is a set of roughly three whitish teeth embedded in another fragment of bone; this is a lizard jaw fragment.
