Fat Boy Posted October 23, 2008 Share Posted October 23, 2008 I found this tooth a couple years ago and wasn't sure what it was, and filed it away in my "to be identified later" box. Well, I was going through that box the other day and took this one out for a pic to share with y'all. I think that it's a Galeocerdo contortus parasymphyseal tooth. Sorry, the pics aren't very good and I vow to post better ones soon. The cutting edges of the blade are lightly serrated. Do you all agree with my identification?

Guest bmorefossil Posted October 23, 2008 Share Posted October 23, 2008 With serrated edges???? it doesnt look like it has any, looks like it has a cutting edge Link to comment Share on other sites More sharing options...
PaleoRon Posted October 23, 2008 Share Posted October 23, 2008 I don't see any hint of serrations but that may be due to the pic quality? Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted October 23, 2008 Share Posted October 23, 2008 I don't see any hint of serrations but that may be due to the pic quality? yea and a cutting edge can be seen on the side view picture Link to comment Share on other sites More sharing options...
Fat Boy Posted October 23, 2008 Author Share Posted October 23, 2008 The cutting edges are definitely serrated. The pic quality isn't so good. I'll try and get better pics. Sorry about that. I've heard of makos being serrated before (Hastalis), but this tooth was found at Brownies and I would think that those sediments would be a bit too old. But, what do I know? Thanks for the input thus far, tomorrow I'll have better pics. Kevin Wilson Link to comment Share on other sites More sharing options...

Guest bmorefossil Posted October 24, 2008 Share Posted October 24, 2008 Was gw around at that time? idk really, i have never seen a gw actually found along the cliffs so i really wouldnt know. im thinking its not because you would think the serrations on the thing would stand out if it was a gw Link to comment Share on other sites More sharing options...

Auspex Posted October 27, 2008 Share Posted October 27, 2008 If it were mine, the label would say Galeocerdo contortus (whether that's right or not, it has the look).

Fat Boy Posted October 31, 2008 Author Share Posted October 31, 2008 Thanks everyone. I tried to take a pic using my scanner and it didn't turn out very good. I'll try again with the camera. The cutting edge definitely has fine serrations. Thanks for the update on the tiger shark genus change. I read the article but haven't yet caught on simply because I'm lazy and don't feel like changing all of my labels yet . But I guess I need to catch up to the times. That said, I have to make some other changes too because I found out that I have more than one type of thresher shark, and also some H. gigas teeth that I didn't realize that I had. One of them is a lower sympyseal tooth, but only half. Man, I'd like to get a whole one of them! It seems that each time I pull a box of teeth out and go through them I find something new, kinda like going on a new trip but much much more local, LOL.

Fat Boy Posted November 6, 2008 Author Share Posted November 6, 2008 and your sure its not just from feeding? Absolutely. Dang it, my last set of pics didn't turn out any better. I'll try again tonight. Plus, I've got another report to post with pics (Paleocene site). Kevin Wilson Link to comment Share on other sites More sharing options...
Fat Boy Posted November 7, 2008 Author Share Posted November 7, 2008 OK, finally, I have some better pics. I had to adjust the settings on my camera to get better resolution.
