Each toe bore a hooflike ungual which was sheathed in horn. The smaller fingers are clawed, with the ungual size varying among species. The upper skull part was close to the ungual phalanges of a sloth. "C. globosum" are human allergens and opportunistic agents of ungual mycosis and neurological infections. The lower tubercle, where the flexor tendons attached to the ungual, was thick and robust. The enlarged ungual, however, is unknown in "Masiakasaurus". The pads are generally poorly developed, as are the ungual tufts. A claw is a highly modified ungual phalanx. The second pedal ungual is preserved at in length and is estimated to reach restored. Two lateral ungual spines project proximally from the apical tuft. The ungual of the fourth toe was tall, curved, and sharply pointed. The fossil YPM 5205 preserves a large, strongly curved ungual. Short ungual tufts of hairs surrounding the bases of the claws are present. The longest manual ungual phalanx recovered measured in length. Elephants and ungulates have ungual phalanges, as did the sauropods and horned dinosaurs.
