Upper Carboniferous (Duckmantian) Fish/shark tooth from coal measures. N. Wales.
Skatetom posted a topic in Fossil ID
Hi people! I'm a PhD student studying a Duckmantian fossil forest in North Wales. I have found these phosphatic fish/shark? teeth and scales I need an ID on. I suspect they are Adamantina Foliacea (Cuny and Stemmerik 2018) but that is a marine shark and this sequence is almost certainly completely freshwater and thought to be an upland swamp. I'm currently doing isotope work on the nodules and plant fossils and that appears to be confirming this is a completely freshwater system. Anyone have any ideas? You'll have to click on the images again once you've opened them to zoom in! Sorry for the poor quality! Thanks, Tom -
Just found this very small, what looks to me like a dermal plate or scute. It is about 5/8 inches long and 3/8 inches wide. Width could have been reduced by chipping. It came from a Florida beach near Jensen Florida. Looks to me something like a gator scute, but not exactly. If gator, it must have been a baby, but I'm thinking maybe something else. Thanks much.

When hunting the Peace River, I find some - many Ray dermals of this general form (not quite as pristine as these phosphate mine versions: I have been finding more of the little "buttons" recently, maybe 5-10 a hunting day. When in the productive areas, I find lots of these which I always thought of base plates for attaching bottom of Ray spines. The I ran into something that I have definitely NOT seen previously. Less than the size of a penny. So, what is this and , am I moving back or forward in time comparing this new arrival with older stuff? Usual suspects: @Harry Pristis, @siteseer, @MarcoSr @sixgill pete@Al Dente @cowsharks

Originally from the Midwest, I've been hunting for fossils for about 50 years and found about two "fossilized sea shells". And this was not from a lack of trying! I moved to Summerville, SC about three years ago for a job that included lots of travel. Now that travel is finished and meeting new friends in the area, I have connected with some kids that stumbled onto something that I think is big! Had I grown up in Summerville, I probably would have change my career to paleontology instead of Electrical Engineering. I am amazed at the finds here in my home town. I have taken my wife and kids including their friends to a spot that allows them to find Shark teeth (at a minimum) within 2 minutes of arriving to an area. My dilemma, I would like to know what these type of "dermal denticles" are. For every 20 shark teeth I find, I find one of these. Please refer to the attached pics. Thanks Matt
