Hey Hi Y'all, I have been searching some very fine (nano) matrix from Shark Tooth Hill. The matrix went through the window screen but not the "grease splatter" screen. I have not taken any pictures with My scope yet, but thought I would show a "teaser" to peak some interest... My finds so far. Largest pieces are about 1 millimeter.

Hey everyone! About 2 weeks ago, the VERY generous @AshHendrick gave a portion of his Aurora pile, straight from the mine! I put it around a wood frame in my yard, and have hunted it for hours almost every day. This will be an ongoing thread, I will prob not update every day, but at least weekly. This is the pile. It's bigger than it looks in this pic (about 5.5 x 5.5 feet [a little less than 2 meters i think]) What I do is I sift into the bucket, so I don't go through it twice. I dump it somewhere else. Day 1 Coral Fish vert I think this is coprolite, but I'm not sure Turtle shell Cool rock with turritella another turritella Big steinkern Sorry about the blurry pic, the only one I took of the ray teeth The shark teeth Find of the day shark tooth in matrix the shells. Appreciate ID's That's day 1. more coming

I often hear collectors identify a certain type of fish tooth as "either wahoo or barracuda", but I have never seen any photos, articles, books, etc. that show how to tell the difference between the two types of teeth. I know that there are positional variations, but beyond that, are many of the teeth very similar for both species, making them easy to misidentify? Or is there a way to easily distinguish between them? I am referring to specimens collected in the Oligocene beds of S.C. if that helps any. Photos or illustrations would be helpful.

Dear friends, I found this fossil in the desert near my city, Riyadh, Saudi Arabia. Can you kindly help me to identify it for my collection? It is 14 mm long and 8 mm high. I found many sizes. Thank you, very much.

Does anybody recognize this? I'm guessing a dermal denticle, but the elongated shape is unusual to me. Other microfauna in the matrix includes shark(cladodont) teeth, fish teeth, gastropods, goniatites, crinoid and echinoid plates and spines, ostracods, brachiopods, bryozoan, and conodonts. For scale field of view= ~1cm. Magnification 20X Magnification 40X

More Treasures from the Cretaceous Anthills - Domed Teeth
Arizona Chris posted a topic in Micro-paleontology
Hi all, As we continue to wash, sieve and go through one teaspoon at a time our gravels from the sides of giant ant hill mounds from the Twowells Tongue of the Dakota, we are finding some very exciting microfossils! As you recall, we found ourselves on the top of a large rounded hilltop a few months back with very rare limestone on its cap. Most sediment from this formation is either a yellow sandstone, or shale. The Ants did all the work - They brought up pieces of material from the depths of the usual stuff, mostly small gravel pieces and sand. But mixed in has been a plethora of microfossils. Besides the tons of giant forams I posted last time, we have hordes of shark and fish teeth. Can you imagine a red fire ant about 1/4" long carrying a perfect fossilized shark tooth out of its burrow? (yes they bite!) Here are some representative of what some us were calling "Ray or Skate teeth". IVe put them under the microscope at 10x and did a dark field illumination. Most are top up and a few bottom up so you can see both sides. They are roughly 2-3mm in size and are a bit oblong. Most are flat topped domed, but many are more pointy and spherical in shape. My thoughts are some sort of pavement crushing shark which ate molluscs? What do you think, I don't have much experience with fish teeth, but we are sure finding some beauties!

From the album: TEETH & JAWS
Here is a group of fish pharyngeal tooth-plates from a Plio-Pleistocene site in the Santa Fe River. Both freshwater and saltwater fish may have these plates, and both sorts of fossil fish are to be found in the river. More than one species may be represented in this group.

Here is a close-up of a trio of fish pharyngeal tooth-plates from a Plio-Pleistocene site in the Santa Fe River. Both freshwater and saltwater fish may have these plates, and both sorts of fossil fish are to be found in the river. More than one species may be represented in this group.

These were all found in the downstream parts of Big Brook in Monmouth County NJ. I'm quite certain that the one on the left is an Enchodus and am wondering if all three are.

In addition to a growing count of cookiecutter shark teeth (and the usual common variety of tiny shark teeth from my recent batch of cookiecutter shark micro-matrix, I've found a few other potentially noteworthy items that I'll present here for show-and-tell and possibly a bit of help with some of the IDs. First up are a collection of small bits that are either coprolitic or geologic. I've found several of these and so I've saved them while I try to determine if they are indeed trace fossils from the back side of some animal that made a unique contribution to my micro-matrix or, instead, if they are some sort of geologic geode-like concretion. Here's a photo to illustrate my confoundation: You can see from the photo above that these whitish items are lumpy and slightly elongate and a few have a trailing "tail-shaped" extension. The one in the lower right corner measures out at approximately 6 x 6 x 9 mm. The item in the upper left is lumpy on the backside like the others but the side shown is broken and shows the interior with what appear to be calcite type crystals. I don't know enough about coprolites to know if a hollow crystalline interior precludes these from being coprolites or not. Any experts on this subject are welcome and encouraged to weigh in. Cheers. -Ken

Not to long ago, forum member Caldigger sent me a box of Shark Tooth Hill bonebed material. I finally finished going through it and photographing them today. I only took pictures of the best ones, and I have a lot of other partials. I managed to take these pictures with an extremely simple setup: I cut a hole in the bottom of a clear plastic cup, stuck the bottom of my microscope's lens through it, and voila Feel free to correct me in any wrong identifications. Here are some Squalus to start us off: I think they are S. occidentalis. Here are some basking shark teeth, Cetorhinus: Carcharhinus sp.: Some dermal denticles: Tiger shark tooth, Galeocerdo aduncus: Continued in next post.

Recently I traded with another forum member, jcbshark. In exchange for my fossils he sent some gravel from his local river. This river is rich in cookie cutter shark teeth, which I am pretty sure are rare in most places. Anyway, I searched the material and found a lot of nice shark and fish teeth, including four complete cookie cutters and two crowns. I also found what looks like a piece of a ray barb. I hope you like these pictures, 'cause I had to take like a million to get these ones. at least you can see these! most of them ended up looking either like tiny smudge on the camera lens, or just solid black. Don't know why it does that. Anyway, here are the best ones. Cookie cutter shark teeth: I love that red and blue striped crown on the bottom. Ray barb: Whale shark tooth? This one was especially hard to photograph, as it is more 3D and isn't flat like most shark teeth. More pictures later! (EDIT: The pictures are being ridiculous... To view these three, you will have to check my other post.)

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 site once again and reviewed pics of a basking shark tooth. I have never actually found one or seen one in person, so I guess I'm just looking for confirmation on this one. Any ideas?

I got some Lee Creek material, and I was sifting through it when I found these. I think these are barracuda teeth. Pungo River formation.
