From the album: Pisces
Basking shark. Not sure about this id, but it's the closest I could come up with. 7mm. From the Miocene Burdigalian at Billafingen, Baden-Wuerttemberg. -
Took another trip to one of my Miocene Burdigalian sites on my bike again today and I was just wondering if this set of teeth might come from a Notorynchus cepedianus shark.

Astoria Formation Fossils From Oregon Coast
RainBoKatchr posted a topic in General Fossil Discussion
I have been an avid collector of Astoria Formation fossils from the Oregon coast for a number of years, and plan on putting up a web page that shows every known invertebrate species from the Newportian stage of the Astoria formation (plus as many vertebrate and plant species as possible). In my collection I am still short by a dozen or so invertebrate species out of the nearly-100 described in the literature, although I have also found a dozen or so that AREN'T in the literature, and plan on describing and naming them if they are indeed "new" species. So I was wondering if there were any fellow collectors that have unusual stuff that they could share photos of. One of my recent finds was a conifer cone (shown below), although I don't know what genus and species it belongs to (does anybody know?).

A large male tusk a Miocene Rhinoceros has been in my possession for a couple of weeks. I am aware of a couple of businesses which specialize in restoration of fossils, megs, artifacts and the tusk owner asked me to facilitate restorations. The tusk itself is of very high quality with or without restorations. I have a small Rhino collection and I am considering negotiating a purchase price that both of us could feel good about. So here it is. A lower left tusk of Teleoceras Proterum, which was endemic to Florida 8-10 myas. You can see where the tusk was broken between the 5 & 6 inch mark and repaired sometime in the past. A top restorer could erase the mess around the repair, replace the bonding with a like colored material, and come close to making the break disappear. One of the few sources of this level of detail quality occurs in the Florida Phosphate mines. This one was found in a Polk County mine in the 1980s. To my never-ending pain, I did not start hunting until decades later. The next photo is of a T. Proterum skull found in Florida and re_assembled with (I am sure) some restoration. I have circled in red the equivalent fossil left tusk. The animal would sharpen the two lower tusks with the single roundish upper incisor. A couple of more photos. Here is detail on the tusk root. I have colored yellow a small pebble that I have not chosen to remove .. yet. Note the unbroken tiny knobs and the bluish tint to the inside of the root. Finally, a discussion of the tusk tip which could also be a candidate for restoration... So, the mahogany area of the tip has been shaved and polished by the upper incisor for most of the animal's life. Then it was broken on an angle (the grayish , white section). That new gray-white section was then shaved and polished by the upper incisor. This is similar to badly breaking a large bone an have it heal before you die. Your bones (or tusk) will always tell a story. The area next to the red line is a post fossilization "fresh" break and candidate for restoration. So, should I buy it and if I do, what level of fossilization is appropriate? I am not a big proponent of restoration. I have some time to think, and while I do, decided to share this fossil with TFF members. What is the good of having a nice fossil if you never show it to someone who might appreciate it. Enjoy. Jack

I have found a few of these over the years, but it was only recently that I looked closely enough to see that they were not broken bits of the fossil barnacles clusters that litter the beach. The shape, color and texture are actually quite different from the barnacles at this location. This one was excavated from a chunk of landslide material that also contained index fossils of the Drum Cliff Member.

From the album: Calvert Cliffs
This view of the cliffs in Calvert County, Maryland is gorgeous. I don't often see quite the vivid color range in this formation. I didn't linger, though, and I was wading in the bay to keep my distance. See those trees at the top of the 40 ft +/- cliff? The ones with the roots hanging over the edge? Those aren't going to be at the top of the cliff for long. At this point, they are probably only still there out of sheer habit. We did her a landslide the night we arrived, the spoils of which are in some of the following images in this album. I was on a trip earlier in the year, at a different part of the cliffs, when someone did get hit in the head by a bit of falling clay. Lucky for her, it wasn't a big chunk or from very high up. She *only* had a concussion. If ever you are close to the cliffs like this, watch and listen to where you are at all times. Run like crazy if you hear anything falling! DO NOT TOUCH THE CLIFFS! DO NOT STAND ON THE TOP EDGE OF THE CLIFFS! That prize Meg tooth isn't worth your life. -

Collected loose on the beach in St. Leonard, Maryland middle Miocene Choptank Formation Drum Cliff Member Chesapectin nefrens is an index fossil for the Drum Cliff Member of the Choptank Formation, meaning that whatever chunk of matrix one may find fallen out of the cliffs, the precise layer is known so that other fossils in the same block can be identified. These are a very common find at St. Leonard and other places, but I particularly liked the coloration on this one!© Heather JM Siple 2018

Excavated from matrix in the Chesapeake Bay, about 10 feet off of the beach at low tide. View is external on both valves, but hard outer coating has been lost to decay. Valves are pearlescent.

Most bone fragments I find are sticks or chunks; this one is just downright strange. I've not seen a shape like this before. I was wondering if someone could ID what exactly could this be! Thank you!

I haven't visited Flags Pond in ages, as it's not been a very good site for me, fossil-wise. Still, I had a free Friday on July 27, and with the kids in tow, I headed to Flags. It's is a good beach play-wise for the kids, and I hoped the beach would be in good shape after all the rain we've gotten recently. The path to the beach was accessible, the beach itself was in good condition, and there were quite a few people visiting alongside us. Despite the crowds, I walked away with quite a few first finds, including my first odontocete and what I think is my first Cosmopolitodus hastalis. I also found tooth fragments for what could be a large tooth (or maybe I'm just dreaming!). There were tons of bone fragments, ray teeth, and coral pieces washing up onshore as well, and my older kid was thrilled to find some all on his own!

Excavated from landslide material approximately 1/2 mile nw of Matoaka beach access. Found 4 that week. Two survived excavation. This is the only one discovered intact.

Going through the stuff in my bucket that had dried out from my last trip, found more stuff that I can only guess what they might be. The first three are of a tiny disc with holes along the periphery. The next two are of three pieces of a flat discoid "rock", that was more fragile than i thought, looks like from something alive. Last two seem too light for bone, so I'm guessing sponges? Probably some of you will know (penny = 0.75 inches or 19 mm in diameter): Thanks!

I was was catching strippers and drinking gin in Cape Cod a week ago, lower Vermont Sunday and Monday, ate cod in a restaurant on Long Island Sound Tuesday, spent Wednesday in Connecticut, on a plane home Thursday, out hunting fossils yesterday. Did not find much. 10 small shark teeth and a few worn bones. A whiskey bottle from the the 30s or 40s. It was brutal, lots of bugs, 95 degrees, high humidity... Loved every second of it. Had lunch with a good friend, went back to his place to take photos of fossils he found 30 years ago in BV phosphate mines: So think Florida Bone Valley, Miocene, 10-25 myas. I am just going to select individual photos. I have more but sizes limits in a single thread slow me down. A few of these I believe I know the species, but for the 1st day will encourage guesses from those who do not know or are not sure. Enjoy EDITED: Most Identifications added on July 30th Fossil #1: Fossil #2 IDENTIFIED as Large kentriodontid-grade dolphin tooth Fossil #3 IDENTIFIED as true Seal Cervical vertebrae Fossil #4 Fossil #5 IDENTIFIED as true Seal Axis vertebrae Fossil #7 IDENTIFIED as true Seal sacrum bone Fossil #8 IDENTIFIED as Rostral node shark snout. Fossil #9 Indentations on BOTH sides.... IDENTIFIED as symphyseal portion of a mandible where the lateral edges have fallen away - this is from a Large kentriodontid-grade dolphin. I will be thinking about these, looking at the internet fossil sites, checking with fossil identification friends.... Just sharing with my friends at TFF. These are miocene. Out of 9 fossils, maybe I would find 2 or 3 in the mostly Pleistocene Peace River. Jack

After heavy rains for the past week, was hoping stuff would be re-arranged in my creek and new stuff would be visible. The reverse happened; my favorite spots were silted and sanded in. Much of the creek bed had changed water flow, and hardly any of the usual shells were visible just sand everywhere. Good to be hunting again. Most of the frogs were gone (probably eaten) but saw a few fearless ones. So did some digging and screening; nothing big, a bonito nose, a small skate stinger, vertebrae, some broken cow shark teeth, lots of drum teeth, three or four angelshark teeth, and rare (for me) a small rough tiger shark tooth. More rain predicted for the next week, more exploring for me.

This specimen was made incredibly soft by the surrounding matrix. The thin veneer of glossy coloration has worn away, but can be seen on this specimen, which came from the same 2 ft x 1ft x 1ft block of matrix that fell out of the cliff into the bay. Half a dozen of these were collected from that and one other small, adjacent block that day, along with more than two dozen other species. Layer originally designated Shattuck Zone 18. Donated to the Delaware Museum of Natural History.

This specimen shows the original sheen and probably original coloration of the shell. It popped out of the matrix as you see it and required almost not cleaning. This specimen was stabilized, but stabilization did not change the appearance at all. Excavated from a chunk of matrix fallen from the cliffs into the Chesapeake Bay. Donated to the Delaware Museum of Natural History.

Sometimes you just get lucky. This geoduck (pronounced gooey-duck) was sitting with its mate in living state, filled with matrix, under a pile of landslide rubble at the water's edge. The exteriors of both shells were almost completely clean of matrix. Most other specimens were badly cracked in the matrix and would never have survived the fall. This shell was donated to the Delaware Museum of Natural History.

This was carved carefully from a block of matrix that fell out of the cliffs into the bay. Of the dozens that I found, this was one of the few that did not completely fall apart what it was separated from the surrounding sand. Though thicker than many shells in the same chunk of sand, they are extremely soft in this location and incredibly fragile. Donated to the Delaware Museum of Natural History.

Hello, I made a trip to Calvert Cliffs (Miocene) recently and found this interesting jaw segment with four teeth. It looks like some sort of fish to me, but I was wondering if anyone with more knowledge on this topic could tell me exactly what fish it is. Thanks, Evan EDIT: here are the measurements... Jaw... Length: 49mm, Height (including teeth): 27mm, Width: 10mm... Now for a single tooth... height: 11mm-13mm (depending on the tooth), Length: 6mm, Width: 4mm P.S. I tried to post additional pictures but the forum said I could only post 3.95 mb. the photo I origionally posted was 3 mb. I will try to attatch more photos in the comments.
