High school teacher discovers animal fossil older than dinosaurs in Canada

A high school teacher walking her dog along the coast of Prince Edward Island, Canada, discovered the fossilized remains of an unknown animal that roamed the Earth 300 million years ago – about 50 million years earlier than the dinosaurs.

Lisa St. Coeur Cormier, 36, spotted something sticking out of the reddish colored dirt and on closer inspection realized it was a rib cage – then she saw the tether and skull.

The fossil has yet to be identified, but John Calder, a geologist and paleontologist working on the case, suspects it is a type of lizard or a close relative.

Calder told CBC that finds like this happen every “50 or 100 years” and that it “could be a one-of-a-kind fossil in the tree of life… of amphibian evolution. , reptiles, mammals for us,” he said. continued.

Dinosaurs are thought to have lived around 245 million years ago and then died out 66 million years ago.

The creatures that roamed the Earth before were largely sharks, bony fishes, arthropods, amphibians, reptiles, and synapsids.

The fossil found on the beach is small, measuring more than two feet long, but still contains incredible details that have allowed researchers to determine that it lived long before the dinosaurs.

“It’s early in the evolution of reptiles from amphibians, and they’re diversifying,” Calder told CBC.

“And so it’s going to be a real headache. It will probably take a good year to discover the identity of this thing.

Very few pre-dinosaur fossils have been found, so in the end, the one on the beach could be a whole new species.

Ms. Cormier said she was delighted with this rare discovery, because it was her chance to leave a mark on the history of science.

Researchers have carefully moved the fossil from the earth and will carry out tests to determine the animal

“To think that I found something that could be 300 million years old is incredible,” she said.

‘I think it’s gonna be once [thing]but I’ll keep walking around and I’ll keep looking for sea glass and maybe I’ll find something else.

Another set of fossilized ribs was found in someone’s garden in Portugal, but the remains were much larger and belonged to a dinosaur.

After studying the skeleton, scientists discovered that it belonged to an 82-foot brachiosaurus that lived between 160 and 100 million years ago.

The fossils were discovered in 2017, but it wasn’t until earlier this month that Portuguese and Spanish paleontologists announced what they had found – a sauropod dinosaur around 39ft tall and 82ft long .

Axial skeletal elements have been discovered so far, including vertebrae and ribs that indicate it was a brachiosaurid.

The Brachiosauridae group lived from the Upper Jurassic to the Lower Cretaceous.

Unlike other sauropods, they have longer forelimbs than their hindlimbs, resulting in a longer torso and proportionally shorter tail.

Elisabete Malafaia, a researcher at the University of Lisbon, said: “It is not usual to find all the ribs of an animal like this, let alone in this position, maintaining their original anatomical position. “

“This mode of preservation is relatively rare in the fossil record of dinosaurs, especially sauropods, from the Portuguese Upper Jurassic.”

HOW THE DINOSAURS WERE EXTINCT ABOUT 66 MILLION YEARS AGO

Dinosaurs ruled and dominated the Earth around 66 million years ago, before suddenly disappearing.

The Cretaceous-Tertiary extinction event is the name given to this mass extinction.

It was believed for many years that climate change was destroying the food chain of huge reptiles.

In the 1980s, paleontologists discovered a layer of iridium.

It is a rare element on Earth but found in large quantities in space.

When this was dated, it coincided precisely with when the dinosaurs disappeared from the fossil record.

A decade later, scientists discovered the massive Chicxulub crater at the tip of Mexico’s Yucatán Peninsula, which dates to the period in question.

The scientific consensus now says that these two factors are linked and that they were both likely caused by a huge asteroid crashing into Earth.

With the projected impact size and velocity, the collision would have caused a huge shock wave and likely triggered seismic activity.

The fallout would have created ash plumes that likely covered the entire planet and made it impossible for the dinosaurs to survive.

Other animal and plant species had a shorter time interval between generations, which allowed them to survive.

There are several other theories about what caused the famous animals to disappear.

One early theory was that small mammals ate dinosaur eggs and another proposes that poisonous angiosperms (flowering plants) killed them.
