CHENGDU, China, June 11 (UPI) -- Nothosaurs were strange-looking long-necked creatures that lived during the Triassic period, about about 245 million years ago. They resembled a cross between a sea turtle and a dinosaur.
And now, new fossilized nothosaur tracks in China suggest the ancient predators trolled the ocean floor using a paddling motion with their oar-like limbs. The motion not only propelled the animal through the water but stirred up the floor and all its edible goodies -- the two-in-one motion allowing the sea creature to scoop up and gobble down its prey while scuttling along from point A to point B.
