Ancient relative of 'living fossil' fish reveals that geological activity supercharges evolution
The ancient coelacanth, which has existed for some 419 million years, never stopped evolving despite its reputation as a "living fossil." A new discovery reveals that it evolved faster when plate tectonics were most active.
Exceptional new fish fossil sparks a rethink of how Earth's geology drives evolution
Coelacanths are deep-sea fish that live off the coasts of southern Africa and Indonesia and can reach up to two meters in length. For a long time, scientists believed they were extinct.
'Living fossil' fish species has survived for over 400 million years
Ngamugawi wirngarri is a new species of coelacanth, an ancient fish species that has lived on Earth for over 400 million years.
Remarkably Preserved ‘Lazarus’ Fossil Suggests Fish Evolved Based on Earth’s Crust
The two fossil specimens, representing a single coelacanth, were collected during a 2008 expedition to what was once an ancient tropical reef. The recent team CT-scanned them, giving them 3D images of the fish, which is remarkably preserved in three dimensions; many fossilized scales and skull bones are apparent in the acid-treated fossil.
New fossil fish species scales up evidence of Earth's evolutionary march
Climate change and asteroids are linked with animal origin and extinction—and plate tectonics also seems to play a key evolutionary role, "groundbreaking" new fossil research reveals.
Pivotal Ancient Fish Fossils Mark a Key Turning Point in a Slow Evolution
Researchers compare new coelacanth fossils to ones that came before and after and link evolutionary changes to tectonic activity.
New fossil fish species unearthed in Western Australia tied to Earth’s crust movement
Today, the living coelacanth Latimeria (Sarcopterygii: Actinistia) is an iconic, so-called ‘living fossil’ within one of the most apparently morphologically conservative vertebrate groups. It lives off eastern Africa and Indonesia coasts and can reach up to 2m in length.
Exceptional New Fish Fossil Sparks Rethink Of How Earth's Geology Drives Evolution
Coelacanths are deep-sea fish that live off the coasts of southern Africa and Indonesia and can reach up to two metres in length. For a long time,
The World’s Oldest “Living Fossil” Is Shaking Up Conventional Evolutionary Theories
Are the world's oldest 'living fossil' coelacanths still evolving? Groundbreaking fossil research links plate tectonics with significant evolutionary shifts, exemplified by a well-preserved Devonian coelacanth in Western Australia.
