DUBAI, United Arab Emirates (CNN) – The world appears to be a fearsome place during this period due to the development of the Corona virus, but a recent paleontology study may help set the record straight.
A review of 100 years of fossil evidence reveals that 100 million years ago, it could be said that part of the Sahara desert was the most dangerous place on planet Earth, where unparalleled large predatory dinosaurs gathered in any contemporary wild ecosystem.
A fossil analysis of the “Kamkam” stone formation, found in south-eastern Morocco near the Algerian border, dating back to the Cretaceous period, the presence of large-scale carnivorous dinosaurs in one region, in addition to Predatory trackers, all living together in what was at the time. River system full of huge fish, instead of desert.
Objects in the “kmum” area roamed the earth’s surface about 95 million years before the first humans appeared on this planet, but “if you have a time machine that can take you back to this place, it is you probably won’t last long, “according to the study’s lead author. Nizar Ibrahim.
Ibrahim explained to CNN that the ecosystem “like a sleeve” was considered an “environmentally ambiguous place,” since typical ecosystems provide more animals that eat predators than predators, and that predators come in various sizes, with one dominant predator. And bigger
In Kamkam, the fossils of predators outnumber those of plant-eating dinosaurs, and many predators living together in the area, such as the Carcarodontosaurus and deltadromius dinosaurs, were as large as the Tyrannosaurus dinosaurs.
This is unusual “even by dinosaur standards,” according to Ibrahim, because the tyrannosaurus species, which was found in North America after tens of millions of years, served as “the undisputed ruler of its ancient ecosystem.”
“Big-sleeve” predators are unlikely to eat each other. For Ibrahim, the most realistic theory is that he fed on the abundant fish in the area and the sawfish that could reach 25 feet in length.
Ibrahim’s study of the “Kamkum” region with a group of international researchers in the United States, the United Kingdom, Europe and Africa draws attention to the importance of learning more about paleontology in Africa, among other regions of the southern hemisphere.
The forgotten continent
Ibrahim said: “Africa remains, in many ways, a forgotten continent in paleontology, and this study addresses this.”
Although the accessibility and degree of preservation of evidence differ on the African continent, there is still much to discover in Africa.
The Kamkam study shows that African ecosystems “do not simply repeat those we know of in North America, Europe, or other known places,” and also reveal evidence of what happens to life when major changes in climate occur.
Evidence shows in the rock layers, in the “Kamkum” stone formation, that the river system, where predators and large fish originated, eventually submerged in seawater, making the region a shallow sea, and today this same region is in the largest desert in the world.
Ibrahim indicated that paleontology can help us understand “the long-term consequences of the loss of biodiversity, which we are witnessing at the moment.”
