LIMA (Reuters) -Paleontologists in Peru on Monday unveiled the 9-million-year-old fossil of a relative of the great white shark that once inhabited the waters of the southern Pacific Ocean, where ...
The oldest identified coelacanth fossils are around 420–410 million years old, dating to the early Devonian. [ 1 ] [ 48 ] Coelacanths were never a diverse group in comparison to other groups of fish, and reached a peak diversity during the Early Triassic (252–247 million years ago), [ 49 ] coinciding with a burst of diversification between ...

Fossil hunters find different halves of same ancient shark tooth 4 weeks apart in SC Fossil of 94-million-year-old sea creature is unearthed in Utah. ‘Truly significant’
The fact that the bite marks were found on the tooth's roots further suggest that the shark broke the whale's jaw during the bite, suggesting the bite was extremely powerful. The fossil is also notable as it stands as the first known instance of an antagonistic interaction between a sperm whale and an otodontid shark recorded in the fossil record.
A new fossil revealing the complete side view of Ptychodus measured nearly 1.5 meters (about 5 feet) in length, suggesting it was from was of a much smaller shark.
Fossils identical to modern specimens have been dated at over 100 million years old. Modern Queensland lungfish have existed as a species for almost 30 million years. [30] The contemporary nurse shark has existed for more than 112 million years, making this species one of the oldest, if not actually the oldest extant vertebrate species.
In 2004, marine biologists first observed the frilled shark (Chlamydoselachus anguineus) at the depth of 873.55 m (2,866.0 ft), in its deep-water habitat at the Blake Plateau, off the southeastern coast of the U.S. [20] In 2007, a Japanese fisherman caught a 1.6 m (5.2 ft)–long female frilled shark at the surface of the ocean and delivered it ...
