Fossil Shark Teeth of South Dakota


My cousin recently received some matrix from the Carlile Shale Formation of Grant County, South Dakota, USA. He has been carefully breaking it down to extract the hidden fossil shark teeth.  The fossils date to the Cretaceous Period (Turonian). We have been trying to identify what they are. So far names I am considering are Leptostyrax, Cretalamna (Otodus), and Cretodus.

Thanks to Kenny for images.

How To Be A Dunkleosteus


Back in January 2014 I wrote about How To Be A Megalodon Shark which was about the popular smartphone game Hungry Shark Evolution. In that posting, I was hoping they would create an arthrodire or mosasaur creature to play in the game. Well they have created a Dunkleosteus. It is one fearsome creature with some artistic gaming license added in. The creature has been given a double mouth with the inner able to project out like the creatures in the Aliens movie. It is somewhat creepy.


This game is mixing modern fish and sharks with fossil sharks Megalodon (Cenozoic Era) and the Dunkleosteus (Paleozoic Era - Devonian Period). The game designers did pick two of the more popular sea creatures that are shown in fossil sections of museums.

In the game the Dunkleosteus is the most powerful creature revealed so far but in reality the Megalodon was much bigger though not armored like the Dunkleosteus.  The game info screen shown below is amusing by listing "A newly discovered prehistoric colossus. Some say this beast was responsible for the extinction of the Megalodon..." which means it can time travel. The Dunkleosteus was extinct by over 300 million years by the time the Megalodon made is appearance on the Earth.

I saw an interesting fish fossil for sale at the Arizona Historical Society Museum at Papago Park gift shop in October 2014.

The label said, "The Beipiao sturgeon was discovered in the area of west Liaoning Province of China. It was formed in land facies layer of the Late Jurassic Period. It was about 130,000,000 years ago."

If I recall correctly, the length was over 20 cm and the price was $250.
