HI all, Hope everyone has been ok in this crazy year. We were able to self isolate (by about 20 miles) this summer and visited our favourite spot for a bit of fossil hunting near Princeton in South-West B.C. Canada. Our site is near the ghost town of Blakeburn, which can be a neat diversion when you need to take a break from staring at rocks all day. Here are pics of some of the finds from 2020. Pics aren't the best, finds are very small - my hubby has very sharp eyes!! Enjoy!

ID requested: Eocene micro shark tooth from Oosterzele (Belgium)
ziggycardon posted a topic in Fossil ID
Hi everyone! A couple of weeks ago I aqcuired some microfossil samples, one of which was a sample from the Lede Zand, Lede Formation, Oosterzele, Belgium (Eocene, Lutetian, 44 mya). The sample is very rich in Foraminifera & shell fragments, but I also managed to find a tiny shark tooth. While I already searched at belgiansharkteeth.be I can't seem to find a match, perhaps due to it being so small. So I was wondering if anyone here might be able to help me out, I would be very gratefull. Thank you in advance!.thumb.jpg.c822a1b609beda096d066fe3ca36dc9b.jpg)

Hi everyone. Today I had this surface find on a Brazos River mound. Striated face looked like wood, but turned around and looked similar to bone(?). The cross section is whitish. [LxWxT] 1.250” x 0.500” x 0.125”. Could it be a scale/scute or actually wood? Thank you.

I recently found this 9mm by 7mm specimen in matrix from the Eocene Nanjemoy Formatiion of Virginia. I think it is a piece of a Chimaera tooth plate. However, in collecting the Nanjemoy Formation in Virginia for over twenty years I have never found a Chimaera tooth plate or a fragment of one. For that reason I don't want to rule out a coral fragment. However, I haven't found a piece of coral in this formation before either. For comparison, a Chimaera tooth plate (25mm by 16mm) from the Paleocene Aquia Formation of Maryland: What do you think (especially the invertebrate/coral experts)? Marco Sr.

Here's a part counterpart of a leaf I split from the shales of the Allenby Formation at a road cut north west of Princeton, BC. This is the main collection site along the road that runs along the eastern shore of the Tullameen River. Has anybody seen a similar leaf and been able to identify it from Paleocene or Eocene deposits? The veins remind me of Tsukada sp. but this leaf is much narrower. I've also considered a species of Betula (Beech) but again either the leaves are too wide or the serrated edges are larger than what's indicated on this leaf. I'm down to a species of Alnus (Alder) but still can't nail it down. Being a vertebrate guy I need a little help here please.

I have already posted pictures of this partial jaw in a topic “The most rare fossil on your collection” in “Member Collections”. However, I would like to start a thread here in “Partners in Paleontology - Member Contributions to Science” so I can discuss any updates with this partial jaw. I found this partial jaw ( 3mm by 3mm by 1mm) in February 2019 in matrix from the Eocene, Nanjemoy Formation, Potapaco B Member in Virginia. Below are pictures that I took of the partial jaw: I sent these pictures and then the specimen itself to Dr. Ken Rose who is a Johns Hopkins University emeritus and who is associated with the Smithsonian Institution. From looking at the pictures Ken had originally thought that the specimen might be from a hedgehog. However, after receiving and seeing the specimen itself, I got the following statement in an e-mail from Ken “I’ve had a chance to look at your jaw, and it turns out to be significant. It’s not a hedgehog. This is the first primate jaw I know of from the east coast. By all means search the concentrate for any other pieces that could relate to it (premolars would be especially useful)”. This is an example demonstrating that even very good pictures may not be adequate to get an accurate ID of a specimen. Because of the rarity of the specimen I donated it to the Smithsonian Institution. This fossil actually caused the USGS and Dr. Weems to relook at the age of the Eocene Potapaco B Member of the Nanjemoy Formation in Virginia where it was found. I sent matrix samples to the USGS from the hole where the specimen was found and they confirmed that the layer was the Potapaco B Member of the Nanjemoy Formation by looking at the dinoflagellates in the matrix samples. However, Dr. Rose determined that the features of the specimen where much more primitive than the published NP11 date of that layer suggested. So Dr. Weems looked back at all of the research and core samples on the Nanjemoy Formation and determined that the Potapaco B Member of the Nanjemoy Formation was actually about a million years older than previously reported and was in the top of NP10 versus in NP 11. So the age of the specimen was tentatively determined to be 54 to 54.5 Ma. A paper would have been published this spring/summer but Covid-19 stopped everything cold. The Dr. Rose's lab was closed and he wasn't able to compare primate specimens from museum collections because the museums were closed. However progress has been made recently and comparisons with other fossil primate specimens have been completed and a paper is in preparation (first draft is almost done). Figures have been drafted, but there is a problem with the resolution of the scanned images of the jaw, so the jaw may have to be rescanned which requires sending it back to North Carolina. However, optimistically Dr. Rose will submit the paper by the end of this year. I can't say anything about the ID of the specimen until the paper is released. Below is a figure showing representative lower dentitions of Omomyid primates from researchgate.net: Below are pictures showing an artist conception of what an Omomyid primate looked like (alamy stock photo) and a representative Omomyid skull both from Wikipedia.org: Marco Sr.

Some examples of hyperdeveloped corallites in genera belonging to the Stylophoridae family. Certain specialists have come to describe them as aberrant or anomalous. In my modest opinion overdeveloped is a more appropriate qualifier. I hope you find them interesting or at least curious. Cheers.

My youngest son had to go to Denver to pick up a piece of equipment for his business, and like me, he decided to go the round about way and do some fossil hunting along the way. Him and his buddy went to Bonanza and spent 3 days looking and digging around. It took them awhile, he said they didnt find much of anything the first day, just wasting time digging holes, but then ran into a layer that had some decent stuff in it and kept following that layer for about 30 or 40 feet. They also found some insects and one very cool flower. I wish I took a photo of that. I will post more as i get some of this stuff prepped out. RB Here is a cute little leaf. If you look closely you can see where I prepped out the tips of three places and then I prepped out the stem. Came out purty dang good! It still has to be cut with the water saw but just about done. I will be posting more but have to prep it out first.

I found this mystery fossil at the Castle Hayne Quarry near Wilmington, North Carolina over 15 years ago. It was in limestone of the Eocene age Castle Hayne Fm. It consists of parallel shallow indentations that have grayish looking coatings in the bottom of them. I have had suggestions that it was a plant impression, soft coral, and bryozoan. I don't know what fossil forum to have it identified when nobody is sure if it's plant or animal. Any suggestions? The long direction of the specimen is about 3 inches by two or two and a half inches. 7.5 cm by 6 cm

I’m lucky enough to live within walking distance to lots of fossils at Maslin Beach South Australia. The sites in this area are in coastal cliffs of limestone from the Eocene to Oligocene. I’ve found quite a lot of actual marine fossils here but this one I’m not sure about so it would be fun to get an answer from experts! I found this specimen in an exposed cliff face. It looks a lot like bone to me but I guess it could be a really interesting rock Thanks! Aarosaur

Real or fake? rare fish from the US Eocene.
mardopa posted a topic in Is It Real? How to Recognize Fossil Fabrications
True or fake? And what species is it? I have this rare fish from the US Eocene. It has color and a lacquer applied. The rock is authentic and I have passed a flame over the fish and it does not melt, it is not resin. But I still have doubts.

I found this tooth while prepping some of my fossils from the American Fossil quarry near Kemmerer, WY. This is actually in the same plate as a partial stingray that I've been trying to piece back together! I didn't even know the tooth was there until today, weeks after our trip to the quarry! It is very hard, shiny, and completely 3-dimensional. Has some ridges running longitudinally from the base (visible in picture), but these fade out and the top half is very smooth. No serrations. 1cm long, 2-3mm wide. Some quick googling makes me think Crocodile Tooth - there is a picture on FossilsForSale.com that is pretty much identical, and is listed as a crocodile.

My wife and I went on a 7500+ mile ramble to break out of our COVID doldrums. Due to the virus we had to change up many of our original plans... which conversely added a number of additional fossil hunting locals as they allowed us to mostly avoid our fellow humans and maintain social distancing by many many miles. As part of our trip preparations my wife sewed us a number of masks, including a whole series of fossil hunting masks for me. Originally we were supposed to stay in Chicago, but we elected to avoid staying in the city, so we only got to do a drive by We started the trip with a bonus dig, meeting up with fellow forum member @minnbuckeye for a guided Ordovician hunt in Fennimore, Wisconsin (THANKS MIKE!) Unfortunately I neglected to take pics of the site so I will only be able to share a farm pic we passed on the way. Mike was a gracious host who kicked off the visit with a gift of several fossil samples from his home turf As with all of the fossils from this trip, all finds are as they arrived back home, no prep. Some of our finds from Fennimore:

Rains started in ernest today, river hunts will probably be on hold until Spring. Hit another site yesterday in hopes of finding some cetacean goodies or anything worthy of packing out. Found a fish nodule, Aturia fragment with nice color, clams and enough glendonite to cover my neighbors driveway.

This was found today in the shingle at Fort Victoria on the Isle of Wight and the geology is Solent Group so Late Eocene to Early Oligocene. I am aware that lizard jaws have been found here as well as snake vertebrae but this does not look like snake to me so wondered if it might be lizard? Any help to identify would be very much appreciated. Cheers Martyn

Well, I'm in my new habitat out here in Colorado, and while I miss dearly a good paddle on the river and my fossil hunts in the mud and sand, I had to make a trip out to our local spot at the Florissant Fossil Quarry. The kids seemed to dig smashing shale (it lasted about an hour), and the technique actually yielded our first decent leaf fossil. The shale smasher .. in disguise !! Dad, wanted to take a lighter approach and we did come home with a large bag of shale and some plant and insect specimens. I'll post some of those in this thread, eventually when I scan them. Splitting the shale you will often come upon Reaaaaly tiny insects that my failing vision has a hard time catching. This winged insect (a mosquito ?!) had bits on each side of the rock so I scanned and composited him in Photoshop. Didn't turn out too bad. I'll let you know what else I find. Raw Scans: Composite: Cheers, Brett

Hi all, I was wondering if anyone could help me with this tooth... first, I was wondering if anyone could I.D it, it appears to have a cusp, so I’d say no to megalodon, so I’d guess either an Angustidens or Auriculatus... second, I was wondering if you guys think this is just a worn tooth that was in the river for a while, or if it was digested, I saw one for sale that looked similar and said it was digested, so it got me wondering, and I figured it was worth it to at least check on the forum. TIA!

Anyone provide help with an ID on this vertebra? Try as I might, as a serious amateur I've hit the limits of my abilities and could use the collective wisdom. Assumption is that this is a vertebra. Found on the beach on Amelia Island, Florida. I find fossils there routinely and live there part of the year. I find this Forum invaluable to gain knowledge.

At Florissant Colorado (dated to the Eocene) my family and I found these fossils and I would like to I D them to know what I found. I didn’t have a 12 inch/30 centimeter ruler so I used my six inch to make a ruler on a piece of paper it is accurate I promise. 1. 2. 3. 4. 5. 6. 7.
