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 ...
The other two genera in the family, Gandakasia and Himalayacetus, are known only from teeth and mandibular fragments. [3] Retaining large hindlimbs, it was once thought that they could walk on land—indeed, their name means "walking whales"—, but recent research suggests they may have been fully aquatic like modern cetaceans, though the ...
Aetiocetus is a genus of extinct basal mysticete, or baleen whale that lived , in the Oligocene in the North Pacific ocean, around Japan, Mexico, and Oregon, U.S. It was first described by Douglas Emlong in 1966 and currently contains known four species, A. cotylalveus, A. polydentatus, A. tomitai, and A. weltoni.

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 ...
The first fossil found consisted of an incomplete skull with a skull cap and a broken mandible with some teeth. Based on the detail of the teeth, the molars suggest that the animal could rend and tear flesh. Wear, in the form of scrapes on the molars, indicated that Pakicetus ground its teeth as it chewed its food
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 ...
Johannes Gerardus Marie (Hans) Thewissen is a Dutch-American paleontologist known for his significant contributions to the field of whale evolution.Thewissen's fieldwork has led to the discovery of key fossils that have shed light on the transition of whales from land to water, including the discovery of Ambulocetus, Pakicetus, Indohyus, and Kutchicetus.
Millions of prehistoric marine fossils were discovered beneath a California high school over the course of a multi-year construction project. The relics recovered at San Pedro High School included ...
