The pakicetids were digitigrade hoofed mammals that are thought to be the earliest known cetaceans, with Indohyus being the closest sister group. [12] [16] They lived in the early Eocene, around 50 million years ago. Their fossils were first discovered in North Pakistan in 1979, located at a river not far from the shores of the former Tethys ...
Pakicetus (meaning 'whale from Pakistan') is an extinct genus of amphibious cetacean of the family Pakicetidae, which was endemic to Indian Subcontinent during the Ypresian (early Eocene) period, about 50 million years ago. [2]
Late Devonian: 375 million years ago, 75% of species lost, including most trilobites; End Permian, The Great Dying: 251 million years ago, 96% of species lost, including tabulate corals, and most trees and synapsids; End Triassic: 200 million years ago, 80% of species lost, including all conodonts
The first fossil skeletons of whales were discovered in the winter of 1902–03. [1] For the next 80 years they attracted relatively little interest, largely due to the difficulty of reaching the area. In the 1980s interest in the site resumed as four wheel drive vehicles became more readily available.
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago. A teen found a 34-million-year-old whale skull in her ...
Artiocetus clavis was a small whale measuring 2–3 m (6.6–9.8 ft) long. [2] It existed in the early Lutetian age (47 million years ago) and is one of the oldest known protocetid archaeocetes. Though the whale may have been primarily aquatic, the discovery of ankle bones lends to the idea that this fossil may have been a transition between ...
The biological journey of a dead whale’s body to its deep sea resting place—a process known as “whale fall”—is vital for the survival of the creatures who live in these food-poor regions ...
Scientists had worried about Tahlequah’s health seven years ago, as well. She is now in her late twenties, and orcas can live between 50 and 90 years in the wild.. Dr. Brad Hanson, a wildlife ...
