No reason given. Remember to check if both articles share most information before proceeding.

The shark-tooth pattern is a stand-alone fossil that can be donated to the museum in New Horizons. It is possibly the same as the shark tooth fossil.

Donation to the museum[]

In New Horizons[]

When the player presents the shark tooth to Blathers at the museum in New Horizons, Blathers will reply with the following dialogue.

"This shark-tooth pattern comes from the lower jaw of an ancient shark of the genus Helicoprion. Its teeth seem to have grown in a distinctive arrangement rather disturbingly termed a 'tooth-whorl.' I say 'seem' because shark skeletons are made of not bone, but cartilage, except for their teeth. Consequently, their bodies are never preserved as fossils, and questions about their jaws remain unanswered. The size and placement in the stone of the shark's teeth are actually the only things we have to work with."

The shark-tooth pattern is displayed on the right side of the first fossil room, next to the acanthostega and the megalodon.


Further information[]

Main article: Helicoprion on Wikipedia

Helicoprion is a genus of extinct, shark-like eugeneodontid holocephalid fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls"— the cartilaginous skull, spine, and other structural elements have not been preserved in the fossil record, leaving scientists to make educated guesses as to its anatomy and behavior. Helicoprion lived in the oceans of the early Permian 290 million years ago, with species known from North America, Eastern Europe, Asia, and Australia. The closest living relatives of Helicoprion (and other eugeneodontids) are the chimaeras.
