This chapter discusses the criteria used to identify the equid fossils found in Porcupine Cave. Perissodactyl fossils from Porcupine Cave are relatively rare, represented by only 56 fragments of horses (Equus spp.). The equid fossils consist almost exclusively of isolated broken tooth portions or of distal limb elements. Most of this material was recovered from three distinct localities: the Badger Room, the Pit, and the Velvet Room. The morphological criteria utilized in this chapter include body size, inferred from postcranial elements; shape of the protocone, primarily in upper premolars; presence of infundibulae (enamel-lined cups) in some or all of the lower incisors; and length and stoutness of the metapodials and first phalanges.
