Coelacanth fish
The coelacanth fish, found today in the Indian Ocean, is often called a 'living fossil' because its last ancestors existed about 70 million years ago and it has survived into the present -- but without leaving any fossil remains younger than that time. Now, some much older coelacanth remains have been uncovered in a fossil deposit near Bristol by Harry Allard, a student at the University of Bristol, UK. Credit: Harry Allard
The coelacanth fish, found today in the Indian Ocean, is often called a 'living fossil' because its last ancestors existed about 70 million years ago and it has survived into the present - but without leaving any fossil remains younger than that time. Now, some much older coelacanth remains have been uncovered in a fossil deposit near Bristol by a student at the University of Bristol.
While working last summer in Bristol's School of Earth Sciences, Harry Allard, a recent graduate from the University of Exeter, found remains of coelacanth fishes, ranging in size from juveniles to adults, in a section of Late Triassic rocks, dated at about 210 million years old, at Manor Farm, Aust, close to the first Severn crossing.
He discovered the new fossils in a large collection of fish and reptile teeth and bones, representing animals that lived in the shallow seas, and on the neighbouring landmass at that time when Bristol teemed with dinosaurs, and the landscape consisted of numerous tropical islands.
