Drawings demonstrating the recovered bones and how they fit into the tail of the SpinosaurusDrawings: Marco Auditore.
If you spot an exposed patch of the Kem Kem bedsâ red sandstone on the side of a butte, youâre liable to find the mouth of a tunnel too short to stand up in, carved by local miners with a sharpened piece of rebar.When miners come across fossils, they usually sell the bones to a web of wholesalers and exporters. The new discovery means Spinosaurus is the first known dinosaur to take to the waters.“This discovery really opens our eyes to this whole new world of possibilities for dinosaurs,” says Ibrahim.

An assistant professor at the University of Detroit Mercy, Ibrahim, who is of German and Moroccan descent, travels from village to village whenever he visits Morocco, discussing localsâ latest finds in Darija, the local Arabic dialect, over steaming glasses of fresh mint tea.On one such visit to a village outside the town of Erfoud in 2008, Ibrahimâby then a specialist in the Kem Kem bedsâmet a man who had found bones the scientist later realized might belong to a Ibrahimâs research partners at the Natural History Museum of Milan alerted him to even more bones from the same local miner in Italy and helped secure their return to Morocco. New tail fossils reveal that Spinosaurus was an aquatic dinosaur The rocks preserve traces of what was once a vast river system where fish the size of cars once swam. Spinosaurus was even bigger than the T-rex, and new discoveries indicate you wouldn't have been safe even in the water. These bones assemble into a mostly complete tail, the first yet found for Shovels scrape and pickaxes fly as crew members chip away at Moroccoâs Zrigat site, where paleontologist Nizar Ibrahim and his colleagues have been excavating a Delicate struts nearly two feet long jut from many of the vertebrae that make up the tail, giving it the profile of an oar. The newly reconstructed Spinosaurus was undeniably at home in the water. “This dinosaur was actively pursuing prey in the water column, not just standing in shallow waters waiting for fish to swim by. It’s believed to have been up to 18 m (59 ft) long and weigh more than 20 tons, making it bigger even than the Tyrannosaurus Rex. It probably spent most of its life in the water.”To confirm the wider tail was better suited to swimming, a Harvard team created plastic models of the Spinosaurus tail shape, as well as those of crocodiles, newts, and the more pointed tails of other dinosaurs. Team presents groundbreaking evidence Spinosaurus dinosaur was aquatic ... Jon Haworth . But the promise of discovery kept them going, along with Nutella breaks that temporarily took their minds off the punishing work. Nature, 2020.) It broke within minutes. The strength of its propulsion lent further evidence that Spinosaurus was more like a giant crocodile than a land-dwelling T. rex rival. The Nazi director refused, and bombing destroyed the fossils in 1944.
New fossils rewrite the story of dinosaurs and change the appearance of Spinosaurus. The descendants of theropods most likely evolved into modern birds, but Spinosaurus was more dangerous than any bird. “It doesn’t just add to an existing narrative, it starts a whole new narrative and drastically changes things in terms of what we know dinosaurs could actually do.

A major find by Nizar Ibrahim added new pieces to the skeleton, cementing theories that Spinosaurus was primarily quadrupedal and had a … Dino Makers, a museum sculpture firm in Fossalta di Piave, Italy, molds an updated version of the tail for a life-size The device is a robot called the âFlapper,â which dangles beneath a water flume whose flow speed Lauder can control with exquisite precision.
Now a new study, published in the journal Nature on Wednesday, shows Spinosaurus was definitely more Michael Phelps than Eric the Eel.
Some of the fossil bones were 12-inches thick, indicating the tail would have been a powerful mode of underwater propulsion. From 1910 to 1914, Stromer organized a series of expeditions to Egypt that yielded dozens of fossils, including pieces of what he would later name Paleontologist Cristiano Dal Sasso gingerly holds the fourth vertebra from the base of During World War II, Allied bombing prompted Stromerâa critic of the Nazi regimeâto beg the museum director to move the fossils to safety. Lauder, sitting at a workbench, reached for an orange plastic sheetâthe laser-cut outline of a With new bones come new models: Guzun Ion of DI.MA. Locals dig year-round, making them almost certain to find more scientifically valuable specimens than academic paleontologists, who dig only a few weeks a year.Thatâs why paleontologists get to know local diggers and frequently check their hauls. Unsurprisingly, the Spinosaurus tail fin was about 2.6 times more efficient in the water than the tails of other theropods. Days were so grueling that several team members were hospitalized once they returned home. There’s nothing like this animal in over 220 million years of dinosaur evolution, which is pretty remarkable.” Rather than having a tapered whip-like tail, Spinosaurus had a giant fin attached to its backside.
