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.

Paleontology is built on specimens as data points. Trey is one among many of these that help us better understand this extinct group of horned dinosaurs. The fossil spent three decades on continuous loan and public exhibition at a museum, playing a role in advancing scientific study.

In a sudden turn of events last Wednesday the U.S. Food and Drug Administration agreed to review Moderna's new mRNA flu vaccine, according to the company. The announcement came roughly a week after Moderna revealed that the FDA had rejected its application. The company said the agency originally called the plan for the vaccine's phase 3 trials acceptable, But its position changed after top FDA official Vinay Prasad overruled the agency's reviewers, according to STAT.

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.

At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually belonged to a North Pacific right whale and a minke whale-which raised a whole new set of questions. The team's hunt for Alaska's last mammoth had turned into an epic case of mistaken identity, starring two whale species and a mid-century fossil hunter.

Sauropodshumongous reptiles with a long neck and tail and thick, elephantlike legsplayed a starring role in the dinosaur ecosystem, according to a new study. These massive dinosaurs are the largest creatures to ever walk on land. But they also played a crucial part in the food chain, the study authors write, acting as ecosystem engineers. The research was published on Friday in the New Mexico Museum of Natural History and Science Bulletin.

From the beginning, we knew these bones were exceptional because of their minute size. It is equally impressive how the study of this animal overturns global ideas on ornithopod dinosaur evolution,
