[edit: TLDR: DD1-DD13 are denticles. Everything else is likely not.] Here are the candidate shark dermal denticles from my Peace River micro matrix sort (grid lines are 1mm): • DD1-DD13: quite certain in the ID, but can the species be identified? • DD14-DD19: Less confident about these more idiosyncratic specimens. DD16 might just be very worn, or possibly just a lookalike piece of phosphate. might DD17 be a steinkern? Its ridges seem shaped like the other denticles, but the material appears different. Additional idiosyncratic specimens, two orientations each. I am uncertain if they are denticles: • DD20 seems to have ridges, but texture is rough • DD24 has a promising profile, but ridges aren't obvious • DD23 has a rough "base," visible in the lower shot, and overall conical form. What do y'all think?

Hello everyone! I took my daughter and 6 year old granddaughter on a “girls only road-trip” to Hanna Park in Jacksonville, Florida for some relaxation time. We did a lot of beach combing and I found some great fossils. I’ve been able to identify the majority of my haul, but need some ID assistance with a few remaining items. I have a some potential dermal denticles and scutes, and a piece of unknown bone. The bone is is very thin, less than 3 mm. I also have two TINY teeth; one may be a barracuda. I believe the other may be a shark but I haven’t been able to link it to a species. As always, any assistance is greatly appreciated! Thank you

What did Petrodus sharks look like? (Are they known only from denticles?)
Gramps posted a topic in General Fossil Discussion
All, I have been finding a few dermal denticles in Northeast Oklahoma Pennsylvanian shales. Based on published reports and images from our area, I believe these are Petrodus. I’ve attached an image of two denticles I found yesterday. I’ve been looking for images of the entire shark because I’m curious about the animal’s overall appearance; however, I’m only finding images of the denticles. Do scientists know what these sharks looked like, and if so, does anyone know of resources containing overall images? Best wishes.

Hello! Is it possible to identify this scale? May be to order, or family, or genus? Max size: ~ 0,5 mm. There is some relief on the sides of denticle (see arrow). Age: Eocene (Ypresian or Lutetian). Location: Ukraine. Thanks in advance!

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

From the album: Post Oak Creek
To find denticles, you need to go to the finest grain size. This beautiful one could be shark, but I'm not certain.-

Here is another unusual find from the Cookie Cutter matrix. Years ago I found a similar on from a different location. Is it possible to narrow this down to shark or ray?
