Here, the semicircular canals of the most aquatic seal, the rare Antarctic Ross Seal (Ommatophoca rossii), are presented for the first time, along with representatives of every species in the Lobodontini: the leopard seal (Hydrurga leptonyx), Weddell seal (Leptonychotes weddellii), and crabeater seal (Lobodon carcinophagus). Because encounters with wild Ross seal are rare, and few specimens are available in collections worldwide, this dataset increases accessibility to a rare species. For further comparison, we present the bony labyrinths of other carnivorans, the elephant seal (Mirounga leonina), harbor seal (Phoca vitulina), walrus (Odobenus rosmarus), South American sea lion (Otaria byronia).

Megatherium americanum MNHN.F.PAM276 View specimen

M3#14_MNHN.F.PAM276 This model corresponds to a virtually reconstructed bony labyrinth of the right inner ear of the skull MNHN-F-PAM 276, attributed to the extinct giant ground sloth Megatherium americanum. The fossil comes from Pleistocene deposits at Rio Salado (Prov. Buenos Aires, Argentina). The bony labyrinth of Megatherium shows semicircular canals that are proportionally much larger than in the modern two-toed and three-toed sloths. The cochlea in Megatherium shows 2.5 turns, which is a rather high value within Xenarthra. Overall, the shape of the bony labyrinth of Megatherium resembles more that of extant armadillos than that of its extant sloth relatives. Type: "3D_surfaces" 3D view: doi: 10.18563/m3.sf14
