I have a tooth I found in some Lee Creek matrix a couple of weeks ago that is stumping me. As soon as I found it my first thought was Anomotodon, what the heck. Then while doing some research I found where a specimen labeled as Anomotodon cravenensis was ID'd by Case (1980) Here are a few pictures, any thoughts on this. Is this what I have? Any other thoughts on ID? EDIT ... the scale is in mm

Help With Id Of Small Fish Teeth And Possible Basking Shark Tooth
fossilover posted a topic in Fossil ID
All of these teeth have been pulled from reject material taken from the PCS Mine in Aurora, NC. In one of the pictures are a bunch of slender, pointy fish(?) teeth that I keep finding in my micro material. These teeth range anywhere from just a few mm long to about 10 mm. I cannot find anything remotely close to a close match. I have even searched the elasmo site with no luck. The other tooth was found in the same material. At first I thought it was whale shark, but upon comparing them to this tooth the profile just looks too different. I think I got a positive ID when I searched the elasmo -
I started seiving again last week and found this amoungst the bits and pieces. It is from central australia and is albian in age . Found in a marine sediment. I will appoligise for the photo in advance but I havent got a macro camera so I have used the macro setting and added some shots from a digital microscope to show some detail. The scale on the grid paper is 1mm and the fossil is symetrical in shape. Thanks Mike

Greetings All; Thanks in no small part to the help I've gotten here on the forums, I managed to get my fossil dig / identification class off the ground. So far we've had around 400 kids sorting through gravel from Florida and North Carolina, identifying and keeping what they find. I've been stumped by a recent find, however -- a bilatterally symetrical, roughly t-shaped thing about 4mm X 4mm. It's from the Aurora Mine in North Carolina. To me the material looks a little like urchin test, but as the shape is so peculiar I am by no means sure. The scale in the background is 5mm X 5mm. Any

Ok, I have posted this tooth in the past, but I am still wanting to be sure. I believe this is a Galeocerdo aduncus, It was found in Lee Creek spoil material. The thing is it is only 4cm wide at the root and 3cm slant length. Common sense for that size would say Tope shark, however the mesial side of the crown has fine serrations and the nutrient groove while there is not large and pronounced, and it does not divide the root. Please everyone, weigh in on this. The tooth in question, I believe Tiger Shark (Galeocerdo aduncus) : lingual view labial view A definite Tope Shark (Galeorhinus
