MarcoSr Posted January 9, 2016 Share Posted January 9, 2016 Sharks belong to the superorder Selachimorpha in the subclass Elasmobranchii, in the class Chondrichthyes. Listed below are the nine orders of extant sharks. I really believe that to be able to successfully understand and identify fossil shark teeth you need to understand and be very familiar with extant shark teeth. As a result, I’m in the process of acquiring a good number of extant shark jaws which I intend to study and photograph. I’m not trying to acquire the very large grade A type specimens (Wow they cost a lot) but study quality specimens. If you clique on a link you will see a TFF post on the jaw of the indicated species. As I add new jaw posts, I’ll update this list. I’ve included this structure so you can see where each species fits within the Chondrichthyes hierarchy. I hope to be able to add several new jaws per month. These extant jaws can also be found on my family fossil website http://phatfossils.com/ under Extant-References.

MarcoSr Posted January 11, 2016 Author Share Posted January 11, 2016 What a great resource, Marco Sr.. These are really sharp pictures. Julianna Thank you. I have a more difficult time taking a picture of the complete jaw with my camera versus the individual teeth with my microscope. Marco Sr. "Any day that you can fossil hunt is a great day."

It is a lot of work to take the pictures but I'm really learning a lot. I still look forward to taking pictures of the next jaw. Marco Sr. "Any day that you can fossil hunt is a great day."

MarcoSr Posted January 21, 2016 Author Share Posted January 21, 2016 I have now posted 8 extant shark jaws from 6 of the 9 extant shark orders. I currently have another 30 or so jaws from species from those 6 shark orders that I'll post in the future. However, I would like to post at least 1 species from each extant order. I have found a number of sellers where I can buy a species from the ORDER HETERODONTIFORMES. However, I have not been able to find a seller for a specimen from the ORDER PRISTIOPHORIFORMES. Can anyone suggest a seller either on-line or who I could contact to purchase an extant sawshark jaw? Marco Sr. "Any day that you can fossil hunt is a great day."

Marco Sr. I used to see whole sawshark heads for sale on eBay but I don't currently see any on the site. I think eventually some will show up. It is usually the large scale shell sellers that offer them. Link to comment Share on other sites More sharing options...

I think eventually some will show up. It is usually the large scale shell sellers that offer them. Eric A lot of the shark species I used to see on the web I no longer see. The massive number of sharks taken each year by the fishing industry worldwide is really taking a toll on a good number of shark species. I have a number of shell sellers and shark jaw sellers on the web book marked in addition to a number of sellers on e-bay but haven't seen a sawshark in the 4 months that I've been looking for one. Also the cost of a good number of shark species jaws has increased dramatically recently with them now being labeled as rare. If there isn't some kind of worldwide shark conservation effort, many species will definitely become rare. I won't buy any of the large trophy jaws because a lot of those sharks are caught for the shark jaw industry. I also feel badly about buying the jaws of the sharks caught by the millions by the fishing industry. I'll bet 20 years from now a good number of the species I'm buying now won't be available.

MarcoSr Posted January 22, 2016 Author Share Posted January 22, 2016 Very Nice and thank you!!!! You are welcome. It will take me a while to take pictures of the other 30 or so shark jaws from different species that I currently have and I will continue to update the above post with the new links as I post them.
