I have decided to create some collection threads for various shark teeth. I would like to use these to promote some of the less frequently seen shark teeth. We see plenty of Megatooth, GW's etc but some pretty awesome sharks do not get much love here. I wanted to set this up by taxonomic orders and see what my fellow shark nuts want to share. I think this is a great way to not only share our collections but also build a database that may help help collectors ID teeth or get some idea of what exists to be collected. I love Squaliformes sharks. They are among the the most biologically interesting sharks to have existed. Among the truly fascinating adaptations they have are bioluminescence, biological antifreeze for extreme cold temperature survival, protruding jaws in one species and even pockets ! They represent the smallest sharks but some such as the Pacific Sleeper and Greenland Shark can grow very large. The Greenland Sharks are the oldest known vertebrates on the planet with life spans of possibly longer than 500 years and are the slowest swimming fish. The Largetooth Cookiecutter shark has the largest teeth per body size of any living shark. They are also weird looking sharks that can capture the eye. Google search Rough shark or Pocket Shark or the Viper Dogfish. They are bizarre looking creatures yet perfectly adapted to some of the harshest environments on our planet. For shark tooth collectors they present numerous challenges. Many are deep water sharks with few known fossil locations. Some types of Squaliformes may only be known from one or two fossil sites. Many are small sharks with very small teeth which add to the difficulty in finding them. Rarity creates demand and my experience has shown me that not only are they hard to find, collectors hold on to their Squaliformes teeth. I am not even sure how far back they go in the fossil record as Fossilworks notes Triassic Squaliformes from France but I found no available information beyond a notation. I apologize for the long introduction and biological information that most of you probably know. I am bored educator with no one to educate about sharks lol I would encourage my fellow TFF members to share not only your teeth but your knowledge and fun facts swimming around your brain about the amazing and weird Squaliformes.

Last week i enjoyed my holidays in the Netherlands/Belgium and found also many fossils especially shark teeth. I was in Hoevenen near Antwerp and in many other found locations on the coast. I will post my finds in the next days but I in this case I am not sure with the determination and its probably rare? The shark tooth is around 2 cm long and I found it in the MIocene of Antwerp. In my eyes it looks like a broken Somniosus microcephalus or? Are those teeth rare in Antwerp? Thanks for helping me!
