The Northumberland Formation exposed on Hornby Island, British Columbia contains one of the best known assemblages of Late Cretaceous deep water sharks in the world. The deposit is Late Campanian in age (about 74 million years old). There are 30 species of sharks identified and 17 species were newly named in 2019. These deep water species belong to the Chlamydoselachiformes, Hexanchiformes, Squaliformes, and Echinorhiniformes. They include the rare and highly sought after Chlamydoselachus or Frill shark teeth.
The collection that I am offering was assembled 20 years ago. I have always been very interested in the Hornby Island site since I found out about it 20 years ago, but teeth were never available. Now, I am offering an opportunity to purchase shark teeth from 16 rare deep water species (64+ specimens) including 3 different Frill shark species. Many of these species were newly named in 2019 for the Hornby Island shark teeth since they differed from their European /other counterparts.
An incredible location to build your rare shark tooth collection.
