Tatenectes was a small plesiosaur that lived in a shallow sea that covered much of North America during the Jurassic Period. It had a flattened, boxy body and a long neck, and it swam using four flippers like paddles.1

ደስ ዝብሉ ሓቅታት

1

Tatenectes had a very unusual body shape for a plesiosaur: its torso was flattened and boxy, and its belly ribs were thickened, which helped it stay stable in turbulent water.1

2

The first fossil of Tatenectes was described in 1900 by Wilbur Clinton Knight, who thought it was a species of Cimoliosaurus. That original specimen has since been lost.1

3

Tatenectes lived in the Sundance Sea, a shallow inland sea that was less than 40 meters (130 feet) deep and covered parts of western North America during the Jurassic.1

4

Its teeth were small and thin, with long roots and low enamel ridges, perfect for catching slippery prey like fish and squid.1

5

Tatenectes shared its sea home with other marine reptiles, including the plesiosaur Pantosaurus and the large pliosaur Megalneusaurus.1

6

Scientists think Tatenectes could have used lung deflation to help it dive, just like some modern sea turtles do.1

The first fossil was described by Wilbur Clinton Knight in 1900 as a new species of Cimoliosaurus. In 2003, F. Robin O'Keefe and William Wahl Jr. gave it its own genus, Tatenectes, based on a new specimen found in Wyoming.12
ገና ዘከራኽር
Scientists are still debating whether the gastroliths (stomach stones) found in plesiosaurs like Tatenectes were used for ballast, digestion, or something else.1
