Ancient Bones Posted October 31, 2014 Share Posted October 31, 2014 This was a specimen that was found in TFF member jcbshark's Cookie Cutter matrix. Old bones photographed it for me so that we could get an ID for it. It looks like crab in some aspects, and tooth in others...? Any ideas?

snakebite6769 Posted October 31, 2014 Share Posted October 31, 2014 Looks more tooth like to me, similar to some of the stuff you find at big brook. Cool find! Link to comment Share on other sites More sharing options...
jcbshark Posted November 1, 2014 Share Posted November 1, 2014 Wow Anceint bones, that is pretty odd. It's a tooth of some sort. With what seems to be a hollow root I would think its a fish tooth but the enamel looks more like shark. I hope one of the resident experts chime in, I'm sure one of the micro hunters will be able to help you : ) Every once in a great while it's not just a big rock down there!

Al Dente Posted November 1, 2014 Share Posted November 1, 2014 I'm pretty confident it is a fish tooth but I have never seen one like this. Link to comment Share on other sites More sharing options...
jcbshark Posted November 2, 2014 Share Posted November 2, 2014 We have a lot of toothy fish here past and present, it's compressed like a cuda tooth but certainly not one of those. Most fish here now have conical teeth. I really hope you get some help on this one. Did you try sending and pics to Marco Sr, Sixgill Pete or John Hamilton? Those folks all have a deep understanding of lot of the micro material from this era as well as .Good luck! Every once in a great while it's not just a big rock down there!

Ancient Bones Posted November 2, 2014 Author Share Posted November 2, 2014 Thanks Al Dente, I do hope someone can ID it. Julianna and I are quite stumped at the moment. ' Keep calm and carry on fossiling ' Link to comment Share on other sites More sharing options...

Plax Posted November 3, 2014 Share Posted November 3, 2014 was trying to make it a broken off cusp of a compound tooth but the base is wrong. Is it really 7 or 8mm? That's pretty big. Link to comment Share on other sites More sharing options...
sixgill pete Posted November 3, 2014 Share Posted November 3, 2014 I agree with Eric, that it does seam to be some type of fish tooth. That I am pretty confident about. Also, like Plax said, it is on the large size. The root reminds me of some type of Porgy tooth, but don't take that to the bank. wish i could be more helpful.

Yes, it is 7 mm. Thanks for looking at this Plax. I agree with Eric, that it does seam to be some type of fish tooth. That I am pretty confident about. Also, like Plax said, it is on the large size. The root reminds me of some type of Porgy tooth, but don't take that to the bank. wish i could be more helpful. Thank you for checking this out Don. I will keep my eyes open for anything else that comes close. Maybe someday we will know for sure, and for now, we will call it 'a fish tooth'.

Doctor Mud Posted November 4, 2014 Share Posted November 4, 2014 Reminds me of a saw shark rostral spine. The root looks right but the crown doesn't. The crown on rostral spines is usually more elongate and symmetrical. Do you know how old this material is? Link to comment Share on other sites More sharing options...

I wonder if it's a pathological tooth of some sort and that's why it's hard to pin down? Every once in a great while it's not just a big rock down there!

I assumed it was a fish tooth when I found mine (5mm long). Link to comment Share on other sites More sharing options...

old bones Posted November 4, 2014 Share Posted November 4, 2014 Here is another view of Ancient Bones' tooth showing both sides. The blade is thin compared to other fish teeth that we have looked at which seem to be mostly conical. The outer edge is actually translucent (like the edge on a cookie cutter tooth.)

John Hamilton Posted November 4, 2014 Share Posted November 4, 2014 John, can you put up a side view of your tooth. Don, That is a side view. Did you mean a mesial or distal view? If so it my take some time since I took the original photo in December of 2013 and will need to find the tooth and take pictures. Link to comment Share on other sites More sharing options...
John Hamilton Posted November 5, 2014 Share Posted November 5, 2014 Don, It didn't take me as long as I thought to find the tooth. Here is the original photo and three additional views, Link to comment Share on other sites More sharing options...
sixgill pete Posted November 5, 2014 Share Posted November 5, 2014 Julianna and John. With all of your new pictures, I am wondering if it may be some type of Trichiuridae (cutlassfish).

Don, that just might be it! Figure 2 on elasmo.com's Trichiuridae page looks as close as anything else I've looked at. Especially the blade. Now, if there were just more photos of cutlassfish to compare to... I will keep looking. John, thanks for posting the additional photos. You and Ancient Bones have found something really neat.
