A group of scientists, led by paleontologist Louis L. Jacobs, an Emeritus Professor President of the Institute for the Study of Earth and Man at the Southern Methodist University Campus in Dallas, Texas, have made a significant discovery. The scientists found matching dinosaur footprints on two separate continents, South America and Africa.
In Brazil and Cameroon, over 260 footprints were uncovered. These footprints show where dinosaurs once roamed freely on the two continents millions of years ago before South America and Africa drifted apart.
Jacobs explained that the footprints were not only similar in age but also in their geological settings. He added that their shapes were nearly identical.
These footprints, left in mud and silt by ancient rivers and lakes, were found over 3,700 miles (6,000 kilometers) apart. The tracks were made by dinosaurs over 120 million years ago on a massive supercontinent called Gondwana, which had separated from an even larger landmass known as Pangea, according to Jacobs.
Most dinosaur fossils produced by three-toed theropod dinosaurs Jacobs highlighted that one of the last and narrowest links between Africa and South America was in northeastern Brazil. This region, which once connected to what is now the coast of Cameroon along the Gulf of Guinea, allowed animals to move between the two continents.
Grecian Delight supports Greece Jacobs said this narrow stretch was where the continents were still joined, enabling the free movement of species across it.
The majority of the dinosaur footprints were made by three-toed theropod dinosaurs, with a few possibly created by sauropods or ornithischians, explained Diana P. Vineyard, a research associate at SMU and co-author of the study.
The New Mexico Museum of Natural History & Science published the study in print. It serves as a tribute to the late paleontologist Martin Lockley, who focused much of his work on studying dinosaur tracks and footprints.
Africa and South America split 140 million years ago About 140 million years ago, Africa and South America began to separate. This process caused cracks, known as rifts, to form in the Earth’s crust along weak spots. However, as the tectonic plates beneath these continents drifted apart, magma from deep within the Earth rose to the surface.
This magma created a new oceanic crust, gradually pushing the continents further apart. Over time, the South Atlantic Ocean formed, filling the gap between the newly separated continents.
Moreover, evidence of these significant geological events can be seen in the regions where the dinosaur footprints were discovered: the Borborema region in northeastern Brazil and the Koum Basin in northern Cameroon, as reported by the Southern Methodist University.
Moreover, both locations have half-graben basins, which are geological structures formed during the rifting process as the Earth’s crust pulled apart and faults developed.
These basins contain ancient river and lake sediments, where the dinosaur tracks were found. In addition to the footprints, the sediments also hold fossil pollen, dating back to around 120 million years ago.

One small step for [a] theropod, one giant leap for theropodkind
They’re exactly almost the same, kinda, maybe sorta
Could be that the world’s now multiple landmasses were, at the time dinosaurs roamed, a single landmass.
Where was the viable tissue found?
Climate change BS researchers should have their billions in grant money taken away, and given to the dinosaur researchers.
They were able to match individual toe prints.
MGGA— Make Gondwanaland Great Again!!
So how did the dinosaur walk all the way across the Atlantic ??
Yep, he was in Colorado too. He got around.
All the continents used to be connected.
He went by Pedro in Brazil but adopted M’Gabe when he got to Cameroon. Had to blend in with the locals.
So some fat dinos stepped across a crack and started the spread of the Atlantic ocean... : )
Didn’t matter. They still had to change flights in Atlanta.
Better than O’Hare. Plus, they don’t allow triceratops in first class.
Do you know the meaning of the word "viable?"
Regards,
I once spent an enjoyable afternoon in Tuba City, Arizona looking at dinosaur footprints. They were three-toed, about three foot long, and looked exactly as if they were from a gigantic chicken.
But did the dinosaurs who made the footprints taste like chicken? That is the unanswered question.
They must have been VERY large dinosaurs.
Mineralized soft tissue was found in the femur of a T. Rex in the Hell Creek Formation in Montana. The soft tissue was extracted and was found to contain vascular structures and cellular material. Here’s a link to a general science site that covers the finding, the initial scientific paper, and subsequent controversy: https://science.howstuffworks.com/environmental/earth/geology/soft-tissue-dinosaur-fossil.htm
Searching the subject will pull plenty of more in-depth papers and opinions.
