The Spinosaurus is a sail-backed, crocodile-snouted dinosaur that Hollywood depicted as a giant terrestrial predator capable of taking down a T. rex in Jurassic Park 3. Then they changed their mind and made it a fully aquatic diver in Jurassic World Rebirth—a rendering that was more in line with the latest paleontological knowledge. But now, deep in the Sahara Desert, a team of researchers led by Paul C. Sereno discovered new Spinosaurus fossils suggesting both scientists and filmmakers might have got it all wrong again.
On the wooded lower slopes of the valley are clusters of tall houses, some plumed with wood smoke. There appears to be a lot of building work going on, some of it to repair the damage caused by the 2023 earthquake. The sound of a concrete mixer comes cutting through the cool mountain air mixed with birdsong and human voices.
Researchers have discovered the naturally mummified and skeletal remains of 61 cheetahs, which were hidden deep inside caves in northern Saudi Arabia for hundreds, and in some cases thousands, of years. The find indicates that these big cats roamed the Arabian Peninsula for millennia before they disappeared from the landscape between 49 and 188 years agoevidence that bolsters an effort to rewild the region with modern-day cheetahs, according to Ahmed Boug, general director of the National Center for Wildlife in Riyadh.
Demand for safari holidays is growing, so how can you do it without harming animals, people or the landscape? Last summer, images were shared of a scene in Tanzania's Serengeti National Park - a large group of jeeps and dozens of tourists standing outside taking pictures of 'The Great Migration' and blocking wildebeests' traditional crossing point. Jeep traffic jams have also been widely reported in other parks, including Sri Lanka's Yala, known for its high density of leopards.
Dinosaur fever gripped the Western world during the early 1900s, fueled by the discovery of new, ever larger and more spectacular dinosaurs in Europe and especially in North America. Interest in these fossils was not merely driven by academic curiosity. Dinosaur skeletons and research had become a status symbol for museums and their financiers, whether government or private, and colonial powers turned to their areas of influence to find new remains.
