Spinosaurus had penguin-like bones, a sign of hunting underwater. The enigmatic predator—and its cousin Baryonyx—are the only known dinosaurs other than birds with this aquatic adaptation.

Then, in 2022, a team working with聽 Ibrahim turned to Spinosaurus’ bone structure as another way to聽 test the swimming hypothesis. They looked at bone density, ...

Well, back in 2022, a group of researchers published a paper suggesting that the bone density of the Spinosaurus’ thigh and rib bones could have allowed it to be more of a deep aquatic creature ...

Fabbri’s argument rests on data showing that Spinosaurus bones were dense like existing animals that can fully submerge, like penguins and manatees. Hence, they conclude, along with other findings ...

Scientists created a life-sized model of its tail, based on the bones, and put it to work in the water. The strength of its propulsion lent further evidence that Spinosaurus was more like a giant ...

Spinosaurus also had dense bones, and therefore was most likely a swimmer, the Nature paper concluded. But that bone density analysis was “statistically absurd,” said Nathan Myhrvold, ...

Chicago's Field Museum on Friday unveiled a 46-foot cast of a Spinosaurus skeleton. The Spinosaurus is believed to be the largest predatory dinosaur to have existed.
