The jaws and teeth of a megalodon shark at the North Carolina Museum of Natural Sciences. Image from Flickr user Ryan Somma.Session Law 2013-189, signed by governor Pat McCrory on June 26, 2013, gave North Carolina the following state symbols: state fossil, state frog, state salamander, state marsupial, state folk art, and state art medium.

Selection as State Fossil

The bill was sponsored by Marilyn Avila (R-Wake), Susan Martin (R-Pitt, Wilson), Pat McElraft (R-Carteret, Jones), and Roger West (R-Cherokee, Clay, Graham, Macon). The idea for an official state fossil originated with an eighth grade science project at the Newport Middle School in Newport, N.C. Science teacher Donna Jones came up with the idea of having a competition in which students created displays for different fossils to select one to try and make the official state fossil. Students suggested sand dollars, starfish, coral, mosasaurs and sea urchins. The students voted on January 11, 2013 and selected the megalodon shark. Social studies teacher Gary Abell then contacted Rep. Pat McElraft, who adopted the idea and added it to House Bill 830, which proposed several new state symbols.

About the Megalodon

The extinct megalodon shark (Carcharodon megalodon) first appeared during the Neogene period of the Cenozoic Era, about 16 million years ago. Its name translates as ‘megatooth’ and was named because of its infamous large teeth. The Megalodon was bigger than a school bus, growing up to 50 feet long and weighing 30 times more than a great white shark. Scientists believe the megalodon had the most powerful bite of any creature that ever lived. Their jaws could exert enough pressure to crush a small car.

The Megalodon typically age prehistoric turtles and whales. When hunting, they would first bite off their prey’s tail and flippers so it could not swim away, then they would eat the animal.

Most of what we know about the Megalodon comes from studying its teeth. A shark’s skeleton is mostly made of cartilage which breaks down after the shark’s death and doesn’t fossilize. The teeth, however, are made of a bone-like substance, and can be found fossilized on North Carolina beaches and off the coast. Megalodon teeth can be as large as 6-7 inches long. Elements of the teeth suggest that they were arranged in a broad mouth, from which we can guess that the Megalodon also had a short snout.

The Megalodon went extinct about 2 million years ago, during the Miocene era. It is likely that it went extinct because it was unable to adapt to changing ocean conditions.

North Carolina Session Law

Excerpt from Session Law 2013-189, House Bill 830:

Whereas, the megalodon shark is an extinct shark species that lived over 1.5 million years ago; and
Whereas, the megalodon shark may have reached over 40 feet in length and weighed up to 100 tons; and
Whereas, the megalodon shark had serrated, heart‑shaped teeth that may have grown to over seven inches in length; and
Whereas, fossilized teeth of the megalodon shark have been found in North Carolina and throughout the world...

§ 145-41.  State fossil.
The fossilized teeth of the megalodon shark is adopted as the official fossil of the State of North Carolina.

Where did you find the teeth? Because it looks really cool!

Hi Aubrey,

That's aGREAT question!

The fossil now at the NC Museum of Natural Sciences was reconstructed from fossilized shark teeth found in the Aurora phosphate mine in Beaufort County.  The teeth were found there by an amateur fossil hunter in 1995.  A set of 25 teeth were found together and composed much of the shark's upper jaw and a portion of the lower jaw.

I hope this helps!

Great story. It should be noted that the fantastic specimen of Megalodon pictured in this article is in fact in the North Carolina Museum of Natural Sciences, not the North Carolina Museum of Natural History as stated in the figure caption.
