Troodon Posted October 2, 2014 Share Posted October 2, 2014 The last one is on the small side and as with most of the bone we find its a little beat up.I believe this is a dorsal process of vertebra from a Champsosaurus. They are typically found disarticulated and in a preservation like yours. Link to comment Share on other sites More sharing options...
Al Dente Posted October 2, 2014 Share Posted October 2, 2014 The object in post #73 is a fish rostrum similar but different from Cylindracanthus. A picture of the broken cross section might help in the ID. The small circles in the grooves are tooth sockets. Link to comment Share on other sites More sharing options...
Mtskinner Posted October 3, 2014 Author Share Posted October 3, 2014 The object in post #73 is a fish rostrum similar but different from Cylindracanthus. A picture of the broken cross section might help in the ID. The small circles in the grooves are tooth sockets. It has a round cross section...I'll get a pic of it Link to comment Share on other sites More sharing options...
Mtskinner Posted October 3, 2014 Author Share Posted October 3, 2014 Here's one more stumper I have. It's just over the 2 inch mark and its triangular in cross section. It doesn't appear to be a tooth but if it is it's the only one I have like it. Link to comment Share on other sites More sharing options...

Mtskinner Posted October 7, 2014 Author Share Posted October 7, 2014 Is this a Plesiosaur tooth??? The tooth is 2-1/4" long and 3/4" wide at the base and is round in shape. It was found in the same creek as the rest of the items I've posted...Any thoughts/comments would be appreciated! Thanks, Terence Link to comment Share on other sites More sharing options...
Auspex Posted October 7, 2014 Share Posted October 7, 2014 Holy cow, that's huge! Plesiosaur is my first impression, but I would yield to anyone with more than my paltry experience.

Troodon Posted October 7, 2014 Share Posted October 7, 2014 A really nice plesiosaur tooth. Great locality for a variety of species. Link to comment Share on other sites More sharing options...

Mtskinner Posted October 8, 2014 Author Share Posted October 8, 2014 Thanks! It's the largest one I've seen from our area...just wish the tip was all there! Link to comment Share on other sites More sharing options...
Mtskinner Posted October 22, 2014 Author Share Posted October 22, 2014 Here's another weird item that I can't figure out. Not exactly sure it's even a tooth but looks as though it does have enamel. It's almost completely flat and is 5/8" long, 9/16" wide. Link to comment Share on other sites More sharing options...
tmaier Posted October 22, 2014 Share Posted October 22, 2014 Looks like a solitary coral. http://www.google.com/images?q=solitary+coral&btnG=Search&hl=en&gbv=1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 22, 2014 Share Posted October 22, 2014 Looks like a scute or dermal denticle to me. Maybe someone else will weigh in with some idea.

Al Dente Posted October 22, 2014 Share Posted October 22, 2014 Here's another weird item that I can't figure out. Not exactly sure it's even a tooth but looks as though it does have enamel. It's almost completely flat and is 5/8" long, 9/19" wide. It looks a lot like a Tertiary sawfish rostral tooth. Are there any deposits at the site that aren't Cretaceous?

Troodon Posted October 22, 2014 Share Posted October 22, 2014 It looks a lot like a Tertiary sawfish rostral tooth. Are there any deposits at the site that aren't Cretaceous? Boy, I had the same impression a sawfish rostral tooth. Let's hear back Mtskinner. Link to comment Share on other sites More sharing options...
Mtskinner Posted October 22, 2014 Author Share Posted October 22, 2014 It looks a lot like a Tertiary sawfish rostral tooth. Are there any deposits at the site that aren't Cretaceous? I guess it's possible...this is a picture of some of the sawfish rostral teeth we find. Are you thinking this could possibly be a split root section of a tooth, a large tooth, or a different type of all together? Link to comment Share on other sites More sharing options...
Troodon Posted October 22, 2014 Share Posted October 22, 2014 Those teeth are from a sawshark Ischyrhiza but the ones being referenced are different and Tertiary. Link to comment Share on other sites More sharing options...
Mtskinner Posted October 22, 2014 Author Share Posted October 22, 2014 This particular tooth was found along side the others...well in the same creek. The creek is located smack in the middle of the Selma group...late cretaceous. It's also the only one I've seen as well. Link to comment Share on other sites More sharing options...
Mtskinner Posted November 22, 2014 Author Share Posted November 22, 2014 Here's another one that has me stumped. It doesnt seem to fit in with the other crock or mosasaur teeth we've found in this area. The tooth is just over 2" long and 3/4" wide. It's round in shape with a faceted enamel that has no carinae on either side. Any comments will be greatly appreciated! Link to comment Share on other sites More sharing options...
Troodon Posted November 22, 2014 Share Posted November 22, 2014 I don't think crock teeth are faceted so I would rule them out. Mosasaurs teeth can be so I would lean in that direction. Let's see what others say. Boy you sure have a host of different species in your collecting areas. Nice find. Link to comment Share on other sites More sharing options...
Mtskinner Posted January 29, 2015 Author Share Posted January 29, 2015 I've got a few more that I can't quite figure out. I believe this 1st one is a piece of a turtle shell...its 2" long and 3/4" wide. Link to comment Share on other sites More sharing options...
Mtskinner Posted January 29, 2015 Author Share Posted January 29, 2015 Heres the 2nd one...I know I've seen one of these before but I just can't place it. Link to comment Share on other sites More sharing options...
Opisthotriton Posted January 29, 2015 Share Posted January 29, 2015 First one could certainly be the end of a Trionychid (soft shelled turtle) rib in excellent unabraded condition. Second one could be a heavily abraded Hybodont shark cephalic spine. Link to comment Share on other sites More sharing options...
