Out today with a couple of friends to a Miocene site. Very few Pleistocene fossils found here. I have found similar toebones before. I believe that this is a proximal phalanx from a small cat. It is 31.75 mm (1.25 Inch) in length.

Dominican Amber (La Toca Fm., 20.43-13.65 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Opposing view of same specimen from associated image, weighing 10.0g and measuring (mm) 40x31x20; note the rough, unaltered (i.e., unbroken, natural) exterior of the specimen. Most dominican amber is transparent to translucent, yet this specimen is more akin in appearance to the "butterscotch" variety of Baltic amber; I have not determined if the turbidity is due to microscopic air bubbles, or organic inclusions, though it is most likely the former. This type of dominican amber is sometimes seen as a thin layer/flow overlying transparent material, but this specimen is mostly whole, and it's unaltered exterior does not indicate to its having overlain any previous flows. I uncovered this piece while cleaning a 2kg lot of mine-direct material (La Cumbre Mine).© Kaegen Lau

Dominican Amber (La Toca Fm., 20.43-13.65 Ma)

Small run of amber from the La Cumbre Mine, weighing 2.4g, and measuring (mm) 37x13x8. It consists of numerous successive flows, and contains several small single-phase bubbles; as this specimen does, several others I have (from the same 2kg lot) from this locality also display an interesting "schiller" effect when adjusted in-hand (light reflects off of the flow lines' surface). Biological inclusions are a possibility with this specimen, though I will need to prepare it to confirm this.© Kaegen Lau

Dominican Amber (La Toca Fm., 20.43-13.65 Ma)

Dominican amber from the La Cumbre Mine, from the Cordillera Septentrional. Most pieces range from 5-10g in weight, with at least one containing a large two-phase inclusion (enhydro). Material from this mine frequently presents exterior crusts/aggregates of pyrite (iron sulfide); these were likely formed in a reducing, marine/lacustrine environment, where marine sediments, organic detritus, volcanic material (i.e., ash), and sulfate-reducing bacteria helped to provide the sulfides and iron needed.© Kaegen Lau

The specimen was found at Ernst Quarries, Temblor formation, round mountain silt. This reminds me of a ray plate except the plate is somewhat wedge shaped, with very thin teeth (?). One longer “tooth” remains in the matrix. Sorry I couldn’t clean it up better, while attempting to do so, it popped out of the matrix. I hope to glue it back in place to complete the prep, but the risk of further damage may change my mind. This prep has revealed multiple specimens, changing the plan and approach again and again. Nice problem to have,right? The last photo shows one of three larger specimens in the original matrix. I will seek additional IDs and prep advice in separate posts.

Hello all! Like my other finds, this was found in northeastern Nebraska in a creek that runs through both the valentine and ash hollow formations, which are Miocene, as well as some Pleistocene rock. I’m stumped on this one- some animals pieces I’ve found in the creek include bison, rhino, tortoise, horse…but the modern cow gets thrown in there a lot. This is fairly mineralized… anyone have any idea?

Is it a fossilized claw/claw core? If yes, is it possible to ID the species?
hahnewald posted a topic in Fossil ID
Hello to all, I encountered this piece among a gravel bed at low tide on a beach along the West coast of South Africa, close to Cape Town. A location where fossilized shark teeth, marine mammal bones and vertebrae from the Miocene are found alongside Pleistocene fossils like horse teeth and mammoth tooth fragments. Unfortunately, this piece is not very well preserved owing to the relentless waters of the Cape. I'd be thrilled to know if anybody could assist with an ID, and if so, point to any diagnostic features. Scale bar is in cm. Thanks to anyone having a look.

Out today with a couple of friends to a Miocene site. Very few Pleistocene fossils found here. I have found similar fossils at both Miocene and Pliocene sites.

I found this vertebra sitting in the creek, washed down I guess. It is 4" long, and roughly 3" wide (at "top" and "bottom") and heavy for its size. Sides look like they may have had "wings" that were clipped off? Two pairs of closely set protuberances in the center of one "face" with almost diagonal depressions on the side. Two pale depressions at one end of the other face, with black depressions to the side above (below?) where the wings attach. Dried for over a week. Used to see a lot of big verts in the creek thirty years ago, this one is the only one I've found recently. Makes a nice paperweight. Anyone with any idea what part of the spine this came from? Thanks for any help! Sides first two photos, protuberance face next, then depression face, the a few held:

Normally, I am pretty quick to recognize and toss bone fragments. An unusual texture stops the toss. Here are a couple of finds from last week. Fossil #1 Fossil #2

I am mostly anchored to home for the next week, sorting some finds from last month. My process is to pick up almost everything I see, in case it might be a rare fossil (or fossil fragment) that I just do not recognize. I have always thrown back, donated, gifted 80% of what I bring home and that have become critical to keep my "collection" at a level that my spouse will allow. In fact , now I am closer to 95%.... So, with most of the finds already eliminated: There is a few great finds here, that I am able to ID myself. The ones in blue are those I will probably add to my collections. Everything else goes. Any corrections of my IDs are appreciated. I am trying for an Identification on the Whale petrosal. Even whether it is Baleen or Toothed. Realize that I likely need @Boesse to see this.

Two separate trips (Stratford hall and Douglas Point)
Fossil_Adult posted a topic in Fossil Hunting Trips
I hit the Potomac yesterday after a long hiatus for some Paleocene sharks teeth. I also decided to include a few of my finds from the recent Stratford hall trip, which was pretty decent. I always go to Douglas point for my Paleocene teeth because it’s just a good area and I almost always come back with a complete otodus. This time, that didn’t happen, though I did find a few broketodus teeth so meh. But I did come back with some good stuff, including a monster croc tooth, and a gigantic goblin sharks tooth. I also got a fish jaw with a lot of teeth in it and some other nice stuff, in addition to what I think is either a tortoise or turtle leg spur, which I thought was a large worntodus on first glance. On the Stratford trip, I got some cool Snaggles (not pictured below) some makos, and a drum fish jaw with two teeth on the side that came right out the clay. 6 people walked right by it! Plain as day I don’t even know how they could not have spotted it the thing was very obviously exposed! Anyways, here’s all the spoils.

Thanks for looking.... I have put this piece in the junk pile twice, But I keep pulling it out. Found in SW Oregon, Western Cascades, Miocene, Little Buttes Volcanics. Measures about 30mm by 25mm, Here is a link to the site it was found, in fossil hunting trips. The piece was already split open on the ground and I did not look for other pieces, Because it looked like a stain?

Hello all, I made two drawings (and edited both of them) of a O. Megalodon (Otodus Megalodon) shark. The first one is a pencil drawing (black-white) on a original white background (made it coloured, blue). The second one is a Megalodon smelling whales. Enjoy! Perhaps other people can post here their Megalodon drawings/paintings. Kind regards, Ruben

My first thought was bison on this tooth but it just looks a little different than the rest of my collection. Possibly camel? North Central Nebraska, miocene. @Harry Pristis length-APL= 42mm width- TRW= 35mm

Some of my recent finds. Four ray stinger pieces, a dozen drum teeth. Four angel shark teeth (just to the left of the vert piece). Unusual for me, two small tiger shark teeth (i think the small part of these teeth must break off often); scanned most of the small teeth I found. Broken cowshark and parasymphyseal sand tiger. And a bunch of sand tiger and grey shark teeth.

I found this tooth in Greens Mill Run in Greenville, NC. I’m leaning towards croc due to the size of the dental cavity relative to the size of the tooth, but perhaps it is a mosasaur. It has one carina on the anterior side of the tooth, none on the posterior side. Also, if it is croc, is there a way to identify whether it’s Cretaceous or Pliocene? Or if either croc or mosasaur, perhaps genus ID? Thanks!!!

I visited my favorite shark tooth site just north of the Lake of Constance again recently and just wanted to show off a few finds. If anyone notices that I've made any mistakes with my ids then please let me know. Araloselachus cuspidatus The next two I would call Carcharodon (Cosmopolotidus) hastalis, although I know that some still lump these under Isurus. Carcharhinus priscus And the next two I've identified as Odontaspis molassica.

These fossils were purchased by me from a friend who had received them 30yrs ago. In the box they were in was a paper that read "Miocene, Calvert Cliffs, MD. Though some have argued that they are Florida fossils...I found id's for all but a couple from: "Vokes, H.E., 1957, Miocene fossils of Maryland: Maryland Geological Survey Bulletin 20, 85 p". I was wondering if anyone could id the two left...the single fossil photos? Thanks Greg
