TABLE 17 in A new monachine seal (Monachinae, Phocidae, Mammalia) from the Miocene of Cerro La Bruja (Ica department, Peru)

TABLE 17. — Relative lengths of McI and McII in fossil and extant Phocidae.The length of the incomplete McI of Magophoca brevirostris n. gen., n. sp., which lacks its distal extremity has been estimated by comparison with the McI of MNHN.F.PPI297 that is lacking the proximal epiphysis; addition of the length of the proximal epiphysis of MNHN.F.PPI295 to the length of the diaphysis and distal epiphysis of MNHN.F.PPI297; provides an estimate of the total length of McI. Furthermore, the distal epiphysis of MNHN.F.PPI295 is slightly eroded probably missing very little of the bone; therefore, the length of the McII of Magophoca n. gen. is also slightly estimated. e, estimate for a character due to minor damage.
