Redescription of the Skull of the Extinct Madagascan Giant Tortoise, Dipsochelys abrupta

The only known skull of the extinct Madagacan giant tortoise Dipsochelys abrupta is redescribed. It is similar to the other extinct Madagascar tortoise, Dipsochelys grandidieri, differing in the width of the vomer, in having a ridge on the occipital condyle, and in lacking diverging articular condyles of the quadrates.
