A new study found evidence at least one species of dinosaur may have been an adept swimmer, diving into the water like a duck to hunt its prey.
on December 1, describes a newly-discovered species, Natovenator polydontus. The theropod, or hollow-bodied dinosaur with three toes and claws on each limb, lived in Mongolia during the Upper Cretaceous period, 145 to 66 million years ago.
Both Natovenator and Halszkaraptor likely used their forearms to propel them through the water, the researchers explained. Further research should also look at the environment in which Natovenator lived. The specimen was discovered in Mongolia's Gobi Desert, but there is evidence there have been lakes and other bodies of water in the desert in the past.
The "anatomical evidence is less straightforward" for a swimming Natovenator than it was for a swimming Spinosaurus, he said.
