Zygorhiza ("Yoke-Root") is an extinct genus of basilosaurid early whale known from the Late Eocene (Priabonian, 38–34 Ma) of Louisiana, Alabama, and Mississippi, United States, and the Bartonian (43–37 Ma on the New Zealand geologic time scale) to the late Eocene of New Zealand (43 to 33.9 million years ago).

Zygorhiza kochii is a species of extinct whale known from the late Eocene (around 36 million years ago) of the Gulf Coast of the United States.

review the fossil and consider the need for a reclassification of Ziggy from Zygorhiza to Dorudon serratus. Uhen has focused much of his research on the origin and evolution of cetaceans -- whales, dolphins and porpoises.

These skull and jaw fossils are from a Zygorhiza, a toothed whale that swam over a submerged Florida peninsula millions of years ago. Zygorhizas grew up to 20-feet long and weighed upwards of 2,000 pounds.

Mar 4, 2020 · The extinct zygorhiza whale lived 38 million years ago and reached lengths of 16 feet. With dinosaur-like teeth, it was a fearsome predator.

Jul 11, 2016 · Like with all known ancient whales from its time,‭ ‬Zygorhiza was a predator of other marine animals,‭ ‬hunting either fish,‭ ‬smaller marine mammals or even sea birds when able.‭ ‬The robust teeth and relatively long narrow jaws resembled those of earlier marine reptiles like Mosasaurus,‭ ‬and it’s quite probably that ...

Zygorhiza is much smaller than both Basilosaurus and Cynthiacetus. Zygorhiza also lacks the elongate trunk vertebrae of Basilosaurus. Zygorhiza can be distinguished from Dorudon and Chrysocetus by the presence of accessory denticles on the cingula of the upper premolars (Köhler and Fordyce, 1997).

Zygorhiza ("Yoke-Root") is an extinct genus of basilosaurid early whale known from the Late Eocene (Priabonian, 38–34 Ma) of Louisiana, Alabama, and Mississippi, United States, and the Bortonian (43–37 Ma on the New Zealand geologic time scale) to the late Eocene of New Zealand (43 to 33.9 million years ago).

The fascinating history of Zygorhiza Kochii begins in 1845 when Albert Koch went to Alabama and collected enough material from several localities to assemble a 114 foot skeleton meant as a scientific deception and a traveling public display.
