Romer Interval fossils found in Scotland

Romer Interval fossils found in Scotland

Something happened 360 million years ago during the late Devonian period. A mass extinction event devastated marine and terrestrial life, so that very few fossils have been found that are between 360 and 345 million years old.

The end of the Devonian and the first 15 million years of the Carboniferous period left a gap in the fossil record, known as Romer interval.

Some theories have tried to explain this "gap”, The best known being the one that states that there was a drop in oxygen levels caused by high volcanic activity, so it was difficult to sustain life on Earth, thus giving unfavorable geological conditions for the creation of fossils.

However, paleontologists have found an impressive array of fossils from some recently explored sites east of Edinburgh, Scotland, including the banks of the Whiteadder and Tweed rivers. These fossils include amphibians, plants, fish, and invertebrates.

These scottish discoveries They have uncovered four-legged life forms, some of which were the first to walk the Earth, demonstrating that the five fingers and toes arose 20 million years earlier than previously thought.

Everything is being collected in the fossil record”Said Jennifer Clack, paleontologist and study author from the University of Cambridge in Great Britain. "This gives us a clue as to how quickly the ability to walk on an evolved conventional foot emerged, much faster than previously thought”.

The new information suggests that life recovered from this mass extinction much faster than the researchers thought. They also found carbon deposits along with the fossils.

Sir David attenborough concludes by saying: "One is used to hearing about new fossils that have been found anywhere in the world, but to have found such a place in this country, which is undoubtedly one of the few in the world, in geological terms, is wonderful and exciting.”.
