Hello guys. Recently I have posted couple of pictures of possible stromatolites specimen I have found. I visited the same location today and I have found a couple of more specimens which look like some kind of stromatolites. Any help would be appreciated.

Hello! Here are several photos of a fossilized colony of some sort of worm, or so it appears to me. Please excuse the remnants of clear nail polish I used years ago to increase contrast before I knew better. I came across this in Santa Paula canyon about 2 miles northwest of highway 150 where it turns west at Thomas Aquinas College, Santa Paula, CA. It had washed down decades ago from probably a Matilija Formation exposure. The matrix grain seems quite fine and the rock is very heavy. Although I've been up and down the creek countless times, I've never seen the source bed. Eocene oysters, clams and echinoderms have been collected in the canyon. Thanks for your help.

Hi guys, I thought I’d start a thread for what is in my opinion, one of the most under appreciated group of marine vertebrate fossils. Anyway, to provide some info on these ratfish and why I find them so interesting, primarily I am drawn in by their rarity. Unlike sharks, that shed their teeth on a regular basis, these fish have one set for life! Anyway, enough talk, more fossils, I will start with some very uncommon jurassic ones, if anyone has any, please add to the thread

This tooth was collected from one of the Monmouth County, NJ, mixed Miocene/Eocene sites. The curved shape makes me want this to be a Parotodus benedeni, but it could just be a weirdo Odontaspis, Carcharias, or one of the other more common types of sharks. Would love to hear what you all think.

Tube-shaped marine fossil/junk/artifact from Brazos feeder
jtangandgorditi1994 posted a topic in Fossil ID
Found this on the surface in a Brazos River feeder creek near Houston. It was not near any known exposure, but the Brazos itself transport marine Eocene and Paleocene from up north. It also erodes out Pleistocene bone pretty often. The bank of this feeder creek was sandy with clay underneath. One end of the cross section appears to show something organic within. When looking in from the empty end, the cavity wall is rough but doesn't look like bone-porous. Lick test of the outer surface is positive, noticeably, which makes me think this is marine. Overall, the segment is 1" in (outer) diameter and 1" long. I am still novice at fossil hunting, but this is entirely unfamiliar to me. I would guess baculite or horn coral, but only the because of the shape Any ideas appreciated!!!

Hi everyone, I wanted to confirm the identity of one of the leaves I found in Florissant, CO back in 2017. At one point or another I saw the genus Cedrelospermum pop up on here or instagram associated with a leaf which caught my eye in its similarity to my own. I would be interested in seeing your opinions. compared to images I found elsewhere online

Found this little thing a few years ago in a stream where Eocene Manasquan Formation is exposed (although I can't entirely rule out Kirkwood Fm). The four possibilities that I see are 1) ray tail spine barb, 2) fish fin spine, 3) crab claw pincer, or 4) jaw. This doesn't look like any of the ray barbs or crustacean pincers that I have collected so I am leaning towards 2 or 4. While the color/texture looks similar to the Eocene material from this site, it could be modern. What do y'all think?

Hi there folks, I would like to get identified this internal model of a gasteropod from the Possagno marl formation, upper Eocene, NE Italy (specimen max dimension is 11 cm). Amaurellina angustata is my best guess but I'm definitely not sure. Thanks for the help, Daniele

I went out on a fossil hunt last Thursday to one of the streams I like to hunt at. It was only around 28 degrees F when I arrived so I didn't have the highest hopes. I ended up having my best day both quality and quantity wise! I found my first New Jersey hemi as well as my first tiger shark tooth. Also found a really nice sized sand tiger as well as one that would have been a monster if it was whole. Hope you guys enjoy!!

ID requested: Eocene micro shark teeth from Tielt Formation, Egem (Belgium)
ziggycardon posted a topic in Fossil ID
Hi everyone, yesterday I recieved a lot of shark teeth, 20 of which came from the Egem Clay, Tielt Formation, Egem, Belgium that date back to the Ypresian, Eocene. The teeth are very small sized so I tried a macro lens to take pictures (I apologize for the not always clear images), and I believe most belong to Physogaleus secundus. But I wanted to share my thoughts on the ID's of the teeth and see what your imput would be as I am not an expect on Eocene shark teeth. Tooth 1: Physogaleus secundus Tooth 2: Physogaleus secundus Tooth 3: Physogaleus secundus Tooth 4 Physogaleus secundus Tooth 5: Physogaleus secundus Tooth 6: Physogaleus secundus or Galeocerdo? Tooth 7: Physogaleus secundus Tooth 8: Physogaleus secundus Tooth 9: Physogaleus secundus Tooth 10: Physogaleus secundus Tooth 11: Abdounia minutissima or Scyliorhinus sp.? Tooth 12: Physogaleus secundus Tooth 13: Physogaleus secundus Tooth 14: Physogaleus secundus Tooth 15: Physogaleus secundus Tooth 16: Physogaleus secundus Tooth 17: Physogaleus secundus? Not sure, looks a little different in morphology then the rest. Tooth 18: Physogaleus secundus Thank you in advance!.jpg.67e619d62e895cd6ee29733d4625a1a0.jpg)

My youngest son found this many years ago. When he found it, (lifting big slabs of rock) it was very appearent that is was going to fall apart. I picked up my little 2oz bottle of super glue and was going to glue it up so that it had a better chance of making the trip home? Well, that didnt work so good. I put the tip of the bottle, ( I use those little needle tips) where I wanted to put glue. It wasnt comeing out so I squeezed harder. Big mistake! The tip popped off and the glue came out like a river! Frigin glue everywhere!!! Anyways, the kid was snoopin in some boxes and totes I have in one of my garages and ran into this piece again. About 5 hours later, it came out somewhat decent? I know most folks are gunna love this but seeing it up close and personal I get really picky. I still have bad memories of all the glue! These are some kind of sycamore seed pods from the Green River Formation This is how it came out of the tote. After about 5 hours of air scribe work and lots of concentration A close up of the multi seed pods

Hey everyone! I've visited this site a number of times over the years and finally decided to make an account. I am a fossil hunter from New Jersey. I mainly hunt Cretaceous age fossils but also occasionally hunt Eocene/ Miocene age specimens as well. Looking forward to getting to know you all!

So I have found a significant "load" of mostly bivalves in a very deep water mudstone. This mudstone is very hard, when it fractures it is a lot like obsidian, extremely sharp and extremely hard. The specimen in this image is 3 x 5mm. The calcium shell has very little identifiable structures, yet the cast part seems "fair" crisp. If the shell was removed perhaps shell parts would be shown in the cast for ID. Would you remove the shell (if so how? acidic acid?). Any ideas on how to soften this mudstone, it is as hard but not as brittle as any shale I have seen. G picks don't see to do anything but an 8 pound sledge works:( Imaging done with a Panasonic G9 and Olympus 60mm macro lens using focus stacking.

5 days late my scope arrives late yesterday. Put it together before bed time:) I had read here I believe that you could adapt the triocular camera adapter by using a .96" EP holder. I did but I got rid of the AM supplied connector and used a .96 (with electric tape) to 1 1/4" adapter. Using the snout (1 1/4") that came with my Astro 224 camera it works. Downside is very high Power. However when I am not removing tiny Eocene invertebrates the high power images can be useful (although I do have a regular macro setup for bigger finds). Here is how I got the attached 5 image stack. I use SharpCap to capture single snaps to a folder (Using PNG/color). Then place them in Photoshop in layers, and then align and focus stack. Will be useful in helping to identify the species of snail that this is. I put a .5 inexpensive reduce on the 224 to get usable scale (it is going to be great for real micro fossils and water life in my creek. Snail in image is 2mm long, so while big for a micro fossil I think it still can be called one:)! Not using the 224 that much since I got the larger sensor 294, so its new use will find it atop a microscope instead of a telescope:)I captured the image out to ShapeCap (astronomy software) on my desk using the 50" 4K Tv to view. All in all very happy with the setup. 3x-10x is perfect for digging the small guys out of matrix, high mag's for shell features for species ID.

Need some ID help on this one. Eocene, Keasey Formation, and an inclusion or something inside a concretion. Size of the whole piece is 12 x 15 cm, weighs about 6 pounds. Image 1 - Mollusk on top of something that has included into the matrix #2 is a close up of the mollusk and surrounding area Closeup of the inclusion material More images to follow.

I found both of these on the Potomac in a unique site with Paleocene Eocene AND Miocene exposures. I was not able to identify them, does anyone know what they could be?

I think I've found my "home" here. I have well over 50 pieces (a couple are large - 10-25 pounds) of formation that I've collected over the last three months to "investigate". Mostly sandstone and what I think is deep water mudstone (thought it was shale at first but no layering). Will try the Hydrogen Peroxide to dissolve the sandstones but am at a loss for the mudstones. the mudstones are extremely hard but contain lots of micro deep water (>200 meters) fossils. Any advice? I've included an image in the what I think is a softer mudstone higher up in the Keasy. This is juvenile Dentalium agassizi (20mm in Length) I believe but after a 30 year break I've just gotten back into the game and may be erroneous in my ID. Interesting point is that specimens of Dentalium agassizi were used as the "wampum" of the North American Pacific Coast tribes (have a long PDF on it if any one is interested (Phd thesis I found).

Hi folks, I was looking through some of my older fossils (by which I mean the ones I've had the longest, not the oldest in terms of geologic time) and I was happy to see this guy again. This is Eocene shale from the John Day Fossil Beds in Oregon, acquired back in the day when they did guided tours of the Painted Hills and let you keep some stuff. I've long assumed it to be the impression of a nut of some kind. Was wondering if anyone else had some thoughts on it? The impression of interest is small, probably about 1 inch in diameter.

.These fossils are from Romania. They look like crustaceans ichnofossils. If these Eocene or Oligocene fossils are really traces of crustaceans then what genus did make them? If you think that you can identify them write your opinion here. Thank you very much.

I'd help please. The vendor showed me her monitor screen, showing the hard to read journal entries from the 1950's 1960's. The name shown seems like it should be spelled Astrhelia, not finding what singleyi means? Pictures of Astrhelia palmata Fossilized Coral is a good match. Eocene Claiborne Formation. Stone City, Texas Age range: 33.9 to 11.608 Ma 11 mm long.
