They are similar in shape, age and geological context, said Lewis Jacobs, a paleontologist at Southern Methodist University in Texas, lead author of a study describing these monuments.
The study was released Monday by the New Mexico Museum of Natural History and Science, and was highlighted by CNN.
Co-researcher Diana Vineyard said most of the fossil drawings were made by… Dinosaurs Three-legged dinosaurs, although some may have been inherited by larger four-legged dinosaurs with long necks and tails, or something called ornithischians, a type of dinosaur that had bird-like structures.
The tracks describe how the movements of large land masses represented ideal living conditions for dinosaurs, before the large land was divided into the seven continents we know today.
Jacobs said the footprints were carved into mud and mud, along ancient rivers and lakes that once existed on the supercontinent Gondwana, which was a large landmass that later split to form it. Africa South America, Antarctica, Australia, New Zealand, the Arabian Peninsula, and the Indian subcontinent.
“One of the smallest and narrowest geological connections between Africa and South America was the area of northeastern Brazil, opposite what is now Cameroon, along the Gulf of Guinea,” explained Jacobs.
“The two continents were connected on this narrow piece, so that animals on both sides could move across it,” he said.
Africa and South America began to separate from each other more than 100 million years ago, which caused large cracks in the Earth’s crust, and over time the South Atlantic Ocean filled the gap between the two continents.
In places that crossed the two continents, researchers found traces of dinosaurs and the sediments of ancient rivers and lakes, andpollen Disturbed.
“The plants fed the herbivores and supported the food chain,” Jacobs said.
He continued: “Dinosaur footprints are found in the muddy sediments left by rivers and lakes, recording that these river valleys may have provided unique ways of life and travel 120 million years ago.”

On both sides of the Atlantic, paleontologists have found more than 260 identical dinosaur tracks. Cretaceous period Early, both in Cameroon and in Brazil when they were neighboring countries, knowing that the distance between them now exceeds 6 thousand kilometers.
