Archelon Giant Sea Turtle

Information about the Archelon:

Archelon is a genus of extinct prehistoric sea turtle. These massive marine reptiles lived in the oceans of North America during the late Cretaceous (75-65 million years ago.) They grew to an amazing 12 feet long and weighed over 2 tons. The largest Archelon fossil, found in the Pierre Shale of South Dakota in the 1970s, measures more than 13 feet (5 meters) long, and about 4.9 meters (16 ft) wide from flipper to flipper. Unlike most modern turtles, Archelon did not have a solid shell, but instead had a skeletal framework supporting a leathery or bony carapace. Archelon's closest living relative is the sea turtle known as the Leatherback. • Paper thickness: 10.3 mil • Paper weight: 5.6 oz/y² (192 g/m²) • Opacity: 94% Buy a Digital Download
