ebrocklds Posted August 13, 2007 Share Posted August 13, 2007 here is my latest find. i discovered it while preparing a fossil alligator skull from morocco. i know that shark teeth are common in the phospate mines but this one is unusual due to its size. it is the smallest tooth i have seen. if anyone can id it for me that would be great. also if you have other small teeth / fossils i would love to see the pics. i will post a few more small things later. brock Link to comment Share on other sites More sharing options...
jkfoam Posted August 13, 2007 Share Posted August 13, 2007 Brock, Thats great. What a tooth. Sorry I can't help on the ID though. There are people here that can probably help on the ID. I'm into microfossils. They are my favorites. And I thought I had a small shrk tooth. JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...
ebrocklds Posted August 13, 2007 Author Share Posted August 13, 2007 here are a few more tiny fossils first a dinosaur piece. although it measures over 1 inch it is tiny for a camarasaur claw. it is pictured with another claw that is average sized or just below. next is an elrathia kingii trilobite. believe it or not i have seen them almost half this size. lastly i have a unknown piece from the pennsylvanian limestones. i think it is some sort of fish tooth but i am not sure any help would be very appreciated. enjoy Link to comment Share on other sites More sharing options...
Gatorman Posted August 13, 2007 Share Posted August 13, 2007 That is a beautiful tooth and the trilobite is amazing I've never seen one that small. Link to comment Share on other sites More sharing options...
jkfoam Posted August 13, 2007 Share Posted August 13, 2007 Brock, That small Pennsylvanian tooth looks like a Conodont tooth to me. Conodonts are usually discussed in the last chapter of introductory paleontology text books. (By the time the Prof gets to this chapter the whole class is begging someone to shoot them) Conodonts, have, in the past, been considered to be parts of fish, worms, cephalops, snails or crustaceans. Take your pick. Last I heard they were considered to be parts of a Lamprey type critter. The most interesting thing about them is that they are composed of phosphate and in Arkansas they are the source of the phosphate for the mineral wavellite and varacite. I always use this to bug my mineral collector friends asking them where would they be if it were'nt for fossils. LOL. Oh, back to the tooth. It may be genus Gnathodus JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...
ebrocklds Posted August 13, 2007 Author Share Posted August 13, 2007 jk i am sure that it is not a conodont. it is way too big. i forgot to include the picture with a penny for scale. so here it is. i have found other fish teeth from this same locality. they are very similar to lung fish teeth i have collected in the morrison fm. this one however is similar to some eocene? shark teeth i found in south america a few years ago. here are a few pics. i don't know what this is either for sure but i am always open to suggestions Link to comment Share on other sites More sharing options...

MOROPUS Posted October 4, 2007 Share Posted October 4, 2007 the last tooth you show, looks a lot to an Acrodus shark teeth,but I think this were no Penssilvanian...or yes, because were I live (Spain, Europe), appeared on Triassic.Perhaps in U.S.A appears earlier!! :shark: Link to comment Share on other sites More sharing options...
