Giant dinosaur with crocodile-like skull and spiked back roamed Portugal 125 million years ago

A new study has revealed Portugal was once home to a giant 33ft dinosaur with a crocodile-like skull and spiked back.

Scientists have reanalyzed the fossil remains of a specimen discovered in Portugal in 1999 and say it is a new species.

While early studies suggested the fossil belonged to a dinosaur named Baryonyx walkeri, the new analysis suggests it was actually a new spinosaurid that lived 130 million years ago.

The team named the new species Iberospinus natarioi after Carlos Natario, the amateur paleontologist who discovered the fossil in 1999.

Professor Octavio Mateus of NOVA School of Science and Technology, Caparica, who led the study, said: ‘It is one of the most complete spinosaurid specimens in the world.

‘The addition of another taxon to the diversity of spinosaurids in Iberia suggests that this clade may have originated in Western Europe.’

Meet Iberospinus natarioi

Grow old: 130 million years

Clade: Spinosaur

Size: 33ft long

Weight: 3 tons

Diet: Carnivores, although mainly fish

main function: The back has spines, the skull looks like a crocodile

Iberospinus natarioi was about 33ft long and weighed 3 tons, according to the team.

It has a back full of spikes and wades into the water to hunt, much like a crocodile.

Professor Mateus said: ‘Spinosaurs are some of the most enigmatic arthropods due to their unique adaptability to aquatic environments and their relative scarcity.

“Their diet consisted mainly of fish, although other foods, such as pterosaurs, were consumed.”

While spinosaurs are ferocious predators, they are not as well known as other carnivorous arthropods, such as the T.Rex.

According to the team, this is due to a combination of the fragmentary nature of their fossil record, which is largely based on their isolated teeth and unusual body plan.

Professor Mateus said: ‘This has to do with their ecology, particularly with regard to aquatic environments, which could be as specialized aquatic predators in some cases or as predators. wade the water, like a heron.’

To understand more about the dinosaurs, the researchers digitally reconstructed the bones in 3D and provided the scans for free.

The remains of the new species were found in a dinosaur graveyard about 30 miles south of Lisbon, and include several razor-sharp teeth and skull bones.

‘That should help paleontologists, museums and enthusiasts. You can 3D print bones,’ says Professor Mateus.

Iberospinus natarioi is one of a number of spinosaurids discovered from the Iberian peninsula, suggesting that the area may have been a hotspot for the tribe.

In the study published in PLOS One, the researchers added: ‘Iberospinus increased the great spinosaurid diversity from Iberia despite the detritivorous nature of its remains and it is now one of the spinosaurid specimens. the most complete in the world.’

Research to in a short time After a new species of armless dinosaur named Guemesia ochoai was discovered by researchers from London’s Natural History Museum in Argentina.

Their analysis revealed that Geumesia ochoai was a dinosaur – a group of dinosaurs with tiny forelimbs that relied on their powerful heads and jaws to capture prey.

Professor Anjali Goswami, Lead Researcher at the Museum and co-author of the study, said: ‘This new species of dinosaur is quite unusual for its kind.

“It has several key features that suggest it’s a new species, providing important new information about an area of ​​the world we don’t know much about yet.”

HOW DINOSAURS SAVED 66 MILLION YEARS AFTER

Dinosaurs dominated and dominated the Earth about 66 million years ago, before they suddenly became extinct.

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

For many years, it was believed that climate change destroyed the giant reptile’s food chain.

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

This is an element that is very rare on Earth but is found in very large quantities in space.

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

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

Currently, the scientific consensus says that these two factors are related and that both could be caused by a giant asteroid hitting the Earth.

Given the expected size and velocity of the collision, the collision would generate an extremely large shock wave and potentially cause seismic activity.

The fallout would create ash plumes capable of covering the entire planet and making it impossible for the dinosaurs to survive.

Other species of animals and plants have shorter intergenerational intervals that allow them to survive.

There are several other theories as to what caused the demise of the famous animals.

One early theory suggested that small mammals ate the dinosaur eggs, and another suggested that toxic angiosperms (flowering plants) killed them.
