Tried the Manasquan River today and came up with this shark tooth which seems a little different than the makos, mackerel and goblin sharks I usually stumble upon. Any idea what species it may be?

Local Florida fossil-hunters are familiar with this chunky matrix rock. It is commonly called "Gardner Matrix" or "Micro-Matrix". The material in this post was recovered from an exposure close to the boat ramp at the Gardner locality on the Peace River. (Bone Valley formation, Hawthorn group, Hardee county, Miocene). With most of us locked down due to the pandemic, I have plenty of time to sort through this loosely-consolidated and fossiliferous matrix. It's like fossil-hunting from your back porch. On my last few trips to Gardner, I loaded down my kayak with chunks of this matrix. On one trip, the nose of the kayak was dipping into the water and I was almost too overloaded to paddle back. LOL. This matrix represents an ancient Miocene sea floor. It is made up of tiny pebbles, shells, shell fragments, sand, bone bits (usually cetacean), and shark teeth. Most of the fossils have nice coloration with blue tones being common. I have gotten lucky and found a 2-inch megalodon in this same material, but that is quite rare and has only happened twice to me (one time the tooth was poorly preserved and crumbled apart on me). There are generally two types of this matrix. One is very friable and breaks apart easily with just a light tap of the hammer. You can even crumble it with your hands. The other type is harder and more solid with a orange-tan, iron-rich cementing mechanism going on. This latter type benefits from being wetted with a garden hose while breaking it apart. You can sift this material through a 1/4" and then 1/8" mesh screen to get the little stuff from it. Detail-oriented (and patient) folks can further sift it through a window screen to get the TINY fossils out. Personally, I don't have that level of patience and tiny tiny tiny micro-fossils are not really my thing. So, I sort it through a 1/4" screen and then discard the remnants into the garden. This material is phosphate-rich, so it's good for your plants. I busted up a chunk yesterday and took some photos. This particular chunk had a bunch of tiny shark teeth embedded in it. You can see one of the teeth poking out of the surface. This particular chunk was not very generous. It gave up about a dozen small teeth and a medium-sized chunk of bone or tusk - the latter of which I still need to snap a photo of, but I don't think it's identifiable. I know some of this matrix material has been sold or traded around this forum over the years, so I am curious if anyone else has been searching through it lately to satisfy their fossil-hunting urges during quarantine/lockdown. Miocene sea floor. You can see the chunk of bone hidden inside this piece. Nice little tooth with blue coloration peeking out of this chunk. A little careful work and he's free. Lots of little teeth in this chunk, but no big ones yet.... I'll break up some more material today and update this thread with my finds. Wish me luck! I want that meg!

I found these in Miocene lake bed limestone in central Arizona. Palm, reeds and stromatolites have been found in same layer nearby. I see no radial laminations that may indicate that these are algal growths. What are these round cap like structures? @paleoflor All the ones that I have found are round and 3 to 4 cm across. They are all shaped like spheres with the bottom 55 to 60% “missing”. The first three photos are from the top, side and bottom views. The fourth photo is of one still in the rock. The slight gap around the sphere appears to be an empty mold of the mystery object. The last photo is my drawing of what most of the fossils look like. I have an idea of what they might be. Let’s get some other opinions before I give you mine. 1 top view 2 semi side view 3 bottom view 4 in situ 5 idealized diagram

I'm looking for pecten bivalves for my collection. I prefer material from Europe, middle miocene, Paratethys area.

Hi, longtime lurker first time poster here. I was wondering if you guys can help me ID this concretion my family found years ago near Calvert. I believe it might be a trace fossil of some kind, possibly a burrow or tunnel. I have found similar types at Westmoreland State Park. I can upload pictures from different angles if needed. Any suggestions of what it could be?

I collect fossils in already disturbed areas around Scotts Valley, CA, mostly sand quarries and road cuts. The fossilized sand dollars I've collected date to the Miocene 10-12 million and, from what I understand, most everything found in this area is similar from a chronological point of view. This region was a vast, shallow ocean back then so most of the fossils are aquatic. An intact sea cow from this era was famously collected in this region. The first fossil I posted appears to be coral. The second remains unidentified, but someone floated the idea of a worn sea urchin. Here are a few more fragments. They look like fossilized bone to me, but I'm clueless.

I thought I had a prep thread but cant find it so here we go... I asked the team which one to have a go at to enforce myself to have proper breaks while working from home.. The results were overwhelengly for "roundy" who I have now renamed Sanity. So, if every tea break results in this, I should have it knocked out in a year or so - Just digging some grooves to get the chisel into...

This leaf has burnt a hole in my brain for years. Recently when I looked I found a paper which is either the same location this leaf is from, or a very similar one. https://link.springer.com/article/10.1007/s12303-017-0004-x It lists species found as: Equisetum sp. (rhizome) Sorbus sp. Ulmus sp. Fagus antipofi Heer Pterocarya sp. Alnus arasensis Huzioka Alnus sp. (infructescence) Populus sp. Salixsp. Decodon sp. Acer sp. cf. A. nordenskioeldi Nathorts Acer sp. cf. A. rotundatum Huzioka 3 Acer sp. (samara) “Alangium” aequalifolium (Goeppert) Kryshtofovich et Borsuk Fraxinus sp. Dicotylophyllum sp. Monocotylophyllum sp. Unfortunately even with this I am unable to match this leaf! Thanks for any help

I've also added a collection photo of the other little bits and scraps I found yesterday. Thanks in advance for any help you can give me!

Hello all, I recently returned from Peace River with a few finds, including this 15 mm fossil. I believe it's a small herbivore tooth, but I'm new here so would greatly appreciate help on the ID. Thanks!

I found this interesting bone fragment at Westmoreland State Park (Virginia) on the shores of the Potomac River. (Mostly Miocene marine fauna.) It seems to be broken on one end, but not the other. One side is concave while the other is convex. A friend thought it might possibly be a rostrum fragment? Any ideas what it could be? Thanks!

Found by my buddy on a river gravel bar/bank in southern Minnesota. As I've stated in some previous posts the geology in our area is upper Cretaceous. However, the river where this specimen was found pulse floods and is like a giant gravel mixer. In the past and more recently Pleistocene fossils have been found in the river gravel deposits in my area (mammoth, bison, etc). It general it is very difficult to age by geology/context. I'm hoping ancient horse but more sets of eyes on it are better. What do you think and thanks!? Any thoughts on age? Ancient horse or not?

Pliocene/Miocene Invertebrates, Humboldt County CA.
Spoons posted a topic in Member-to-Member Fossil Trades
Hey everyone! This will be my first attempt at a trade in the TFF. Im offering a variety of fossils from the Price Creek Formation of Humboldt County, Northern California. This formation has been dated to late Miocene early Pliocene. As far as to what I’m looking for in this trade, I love all things Mollusca! Gastropods, Bivalves, Ammonites, Belemnites or Brachiopods, I’ll take them all. Invertebrates of any kind will strike my fancy though. The weirder the better. I’ve seen some Ram’s Horn Oysters that are awesome! I have no qualms about trading for these as a whole set, however shipping would be cheaper. I’m willing to ship anywhere in the United States, if your international I’m afraid that you’ll have to absorb that cost. I really appreciate all the knowledge that members have been forthcoming with sharing. Please pm me if your interested. -Nick -
I found the silicified and brecciated laminar structures in Miocene lake deposits north of Phoenix, Arizona. Could they be disturbed algal mats? I envision a drying algal mat in a lake that is disturbed by an event such as a flood, windstorm, landslide or earthquake. Compare to Kinneyia trace fossil: https://woostergeologists.scotblogs.wooster.edu/2015/10/23/woosters-fossil-maybe-of-the-week-kinneyia-ripples/ Confirmed stromatolites occur nearby in the lake sediments. Photo 1: typical wrinkled/ cracked marks in surface of laminar structures. Photo 2: typical piece of folded and brecciated laminar structures. Photo 3: detail of photo 2. Photo 4: edge of rock in photo 2. 4.5 cm field of view. Photo 5: Another piece. Photo 6: detail of photo 5. Photo 7: edge of photo 5. 3 cm field of view.

To start off, I love whale teeth. They seem to love me also. I find many of them. This one seems different and thus special. In circumference, it is a 3rd the size of my pinky. It is 57 mm (2.25 inches) in length, 7.5 mm wise, and it is all there. Note also that the tip has been shaved by an opposing tooth. and it was found in SW Florida. Is Aulophyster a possibility? Hopefully, Bobby @Boesse can provide options.

Nice weather finally. But with schools closed and people bored at home, have seen increased competition at "my" sites, but yields have been small but plentiful. Fish should be biting soon.

A friend found this bone on the shores of the Potomac River in Virginia... mostly miocene marine fauna. Closest we could find was a picture of an ocean sunfish beak from the Calvert cliffs.. but we are eager to hear what others might think? Thanks!

When I first found this tooth, I paused. Many times I have stated that horizontal banding in the Peace River means one thing--- marine mammal, likely whale. This tooth is very small, could be something like Aulophyseter, but I am no longer so sure. Decided to see if others recognize this tooth.

I am sitting at home, sorting ziplock bags of fossils collected in the last year. You know the problem. Too many fossils in the house. All these fossils came out of a Bone Valley Creek, definitely Miocene. For those of you who are fortunate enough to collect Bone Valley teeth, what is happening with the white on these teeth? Especially the Hemipristis.. A white tip. or the "bourlette" on the Tiger?

Good evening folks. I am requesting a verification/confirmation for a tooth I purchased over 10 years ago listed as Platybelodon, Miocene, Gansu, China. It measures 7cm long, 4.2cm wide and 6.3cm tall.
