‘Crushing’ reptile related to modern crocodiles 230 million years ago unearthed in Brazil
A terrifying ‘bone-breaking’ reptile related to the modern crocodiles that it celebrated in the first dinosaur corpses 230 million years ago has been unearthed in Brazil.
The creature walked on all fours but used its two hind limbs to run, and it was the Tyrannosaurus Rex of its time, the researchers said.
Called Dynamosuchus collisensis, it had a long snout and tail, huge jaws and large, blade-shaped teeth, adapted to eat meat, although it was probably a scavenger.
The creature’s skull was also similar to T Rex’s, and a double row of bone plates ran down its back. It belonged to a group called the ornithosquids.

DYNAMOSUCHUS COLLISENSIS STATISTICS
Dynamosuchus collisensis was a relative of modern crocodiles that lived about 230 million years ago.
The seven-foot-long beast was unearthed beneath a hill in Agudo, southern Brazil.
Its name means ‘powerful crocodile’, a reference to its ‘impressive bite force’.
However, his bite speed would have been slow, suggesting that he was a scavenger.
I would have walked on two legs but I could also have run on two.
The remarkably preserved remains of D. collisensis were found in the so-called ‘dinosaur cemetery’ under a hill in the picturesque Agudo, southern Brazil.
“The extremely rare reptile would have been a true bone crusher since the dawn of the dinosaur era,” said author and paleontologist Rodrigo Müller of the Federal University of Santa Maria in Brazil.
‘This new species is the first of its group in Brazil, and only the fourth that is found worldwide. The last discovery happened fifty years ago.
The first of this group was unearthed in Lossiemouth, in the Scottish Highlands, in the 19th century, while the other two specimens came from Argentina.
Ornitosucidos belonged to the so-called ‘archosaurs’, a group of animals that were divided into two branches, one of which led to dinosaurs and, finally, to birds and the other to alligators and crocodiles we know today.
About seven feet long, Dynamosuchus was at the top of the food chain of its time, when the first dinosaurs had just begun to evolve.
Its name means ‘powerful crocodile’, given as a nod to its ‘impressive bite force’, explained Dr. Müller.
“Dynamosuchus was a” relative “or” cousin “of crocodile, rather than a direct” crocodile “, he added.
‘His large and blade-shaped teeth were adapted to eat meat. But the speed of the bite was low, suggesting that it was a scavenger.

“During the Late Triassic, while the first dinosaurs fought for the small prey, Dynamosuchus collisensis probably looked for corpses, or animals easy to catch,” said Dr. Müller.
‘Some paleontologists say that T. Rex did the same. He also had a good sense of smell, and was probably slow. So both occupied a similar role in terrestrial ecosystems. ‘
Scavengers are extremely rare in the Triassic fossil record.
D. collisensis probably moved quickly when he was running on his hind legs, but he spent most of his time working on all fours.
“Dynamosuchus probably took advantage of the first dinosaurs, lizards and ancestors of mammals called cinodontes,” said Dr. Müller. In the image, a reconstruction of a Triassic
‘Dynamosuchus probably took advantage of the first dinosaurs, lizards and ancestors of mammals called cinodontes. These were strange animals that looked like scaly rats, ” said Dr. Müller.
“This animal probably caught slow animals and looked for dead animals, such as vultures and hyenas today.”
‘Their legs were upright, different from the extended posture of modern crocodiles. In addition, during the rapid march, this animal was able to run in a bipedal posture.
“I lived side by side with the oldest dinosaurs that are about five feet long.”
‘Therefore, Dynamosuchus was a great animal compared to those with whom he shared the planet.’
The full findings of the study were published in the journal. Polon Palaeontological Act.
