Did the dinosaurs ever fly and swim?

Are dinosaurs perhaps the first animals to fly in a double-winged plane when moving in the air?

Paleontologist Sankar Chatterjee and aerospace engineer Joe Templin confirmed that the feathered dinosaur named Microraptor used the same technique as the Wright brothers' first aircraft to fly.

This Chinese-discovered dinosaur carries feathers to fly with its front and back limbs. According to Chatterjee and Tremplin analysis, the Microraptor's legs cannot rotate outwards, so they cannot be placed just below the front wings. Their rear wings are rear-mounted, lower than the front wings, similar to a double-wing aircraft. The two researchers explained this at the annual meeting of the American Geological Society in Salt Lake City.

At the same conference, another group of researchers said traces were discovered in the US state of Wyoming, a swimming bipedal dinosaur. The size of an ostrich, this dinosaur roamed the shore of an ancient inland sea 165 million years ago. The 3-finger footprints of this dinosaur lie next to the traces of other crocodiles and marine animals. The further away from the footprints, the less it becomes, indicating that this reptile can float under the sea.

Researchers are continuing excavations in the ancient sea area covering Colorado and Wyoming to search for skeletons or fossils to help them learn more about this swimming dinosaur.
