This place is called the most dangerous in the history of the world

 


Which place is considered the most dangerous in Earth's history? November 2021, research scientists find the answer.

This place was in the Sahara about 100 million years ago. Quoted from SciTechDaily, this finding is the result of a survey of fossils and geology found in southeastern Morocco known as the Kem Kem Group.


Hundreds of millions of years ago this area had a very wide river and was filled with various land and water species. Some of the fossils found at the Kem Kem Group include three of the largest and most terrifying predatory dinosaurs ever discovered.



Two of the three dinosaurs were Carcharodontosaurus (over 8 meters long and had serrated teeth 20 cm long) and Deltadromeus (about 8 meters long and belonged to the raptor family). There were also flying reptiles such as pterosaurs and predators similar to modern crocodiles.


"This is arguably the most dangerous place in the history of planet Earth, a place where time-traveling humans will not last long," said Assistant Professor of Biology University of Detroit Mercy and lead author of the study, Nizar Ibrahim in a statement.



This study is the result of the collaboration of several universities in various countries including the Universities of Detroit, Chicago, Montana, Portsmouth, Leicester and the Paris Museum of Natural History. The findings were published in the journal ZooKeys.


Scientists found predatory dinosaurs in this area hunting for fish that are found in rivers. David Martill of the University of Portsmouth said the ancient fish in this river were fantastic in size compared to modern fish.


"This place was teeming with very large fish, including coelacanths and giant lungfish. These coelacanths, for example, were probably four to five times larger than today's coelacanths," Martill said.


"There's also a freshwater saw shark named Onchopristis with the most terrifying rostral teeth, it looks like a spiked dagger, but it sparkles beautifully."



To collect data and images of these fossils, Ibrahim had to travel the world to visit the Kem Kem Group fossil collections stored in various countries.


"This is the most comprehensive finding of vertebrate fossils from the Sahara in nearly a century," said Martill.
