That’s what I think when I see this.
One of the Plesiosaurs, large marine reptiles that lived during the late Cretaceous period, 70 million years ago. 50 feet long, weighing 8 to 10 tons, it had a huge turtle-like body and a long snake-like neck and head. They spent their lives in the water, coming out on land to bask in the sun or lay their eggs, just as the modern sea turtle does today. This life size replica may be seen at the Prehistoric Gardens on the Southern Oregon Coast on Highway 101.
