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 (1]
Basilosaurus (meaning "king lizard") is a genus of large, predatory, prehistoric archaeocete whale from the late Eocene, approximately 41.3 to 33.9 million years ago (mya). ). First described in 1834, it was the first archaeocete and prehistoric whale known to scienc
Archaeoceti ("ancient whales"), or Zeuglodontes in older literature, is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene 1] Representing the earliest cetacean radiation , they include the initial amphibious stages in cetacean evolution , thus are the ancestors of both modern cetacean suborders ...
“And it represents an entire ecology of the ocean 9 millions of years ago.” The fossils were first uncovered during the school’s modernization project, which began in 2022.
A high school student made an incredible discovery in her own backyard: A 34-million-year-old whale skull. Sixteen-year-old Lindsey Stallworth and her biology teacher, Andrew Gentry, found small ...
As archaeocetes, Basilosaurids lacked the telescoping skull of present whales. Their jaws were powerful, [9] with a dentition easily distinguishable from that of other archaeocetes: they lack upper third molars and the upper molars lack protocones, trigon basins, and lingual third roots. The cheek teeth have well-developed accessory denticles.
Researchers in Egypt unearthed one of the smallest early whale species. The basilosaurid is the oldest aquatic whale found in Africa, the new study said. Fossil discovery causes monumental shift ...
