Hello, a friend of mine found some kind of large fossilized creature in a cave on Sand Mountain in northeast Alabama. It was buried in red clay. The rocks containing fossilized bone are broken into many pieces; he has collected hundreds of small to medium sized pieces and there are many larger ones still at the site. Most of the creature is still there. The rocks are a sandy yellow color and unusually light weight. I washed one of them (#28) and there was a lot of tiny bubbles forming in different places, showing that the rock is porous. Three of the pieces (see pic below) he assembled into a complete joint. The creature may have been 20+ feet long, and I would guess it's a sea creature, given that the imprint of a seashell is found in one of the fossil rocks. The complete archive of images is here: http://grow.game/files/fossil-pictures-lowres-2021-05-26.zip These are pics of only 32 pieces of the hundreds he's collected. Notes on individual images: #20 appears to be some kind of iron ore. It's unusually heavy. There is another piece just like it also. Could be a clue to the geology of the site. #27 note the shell embedded on one side. #28 looks brilliant orange because it's still wet after washing some dirt off. This is the one that was bubbling in different places.

Hi all My kids and I found this piece at the NSR and saw that there were multiple bone fragments in it. Do you all think that there is a fish jaw in the lower right portion of the specimen? If so, can anyone tell from which type of fish it is? Thanks in advance! Bret

After cleaning these 2 big bois, which are whale fossils. But maybe it's possible some people know what kind they are. If not, can you refer me to someone? Thanks in advance! The biggest is about 18CM in heigth

Anyone help identify this? Its covered in gastropods or so I've been told. Is it considered a mortality plate?

Hi all, hoping I found something with these 3 pieces but thinking prob one or more are those tricky concretions I'm not too experienced with yet. Thanks for any help in advance!!!

A while back I found this fossil in Wisconsin, unfortunately I don't remember where exactly I was when I found it. So far I have been unable to easily identify it. It is about 2 inches across, and about an inch tall. I can post more pictures if needed.

Hi, i have this worn rock that i found in Calvados, Cretaceous or jurassic sediments. I was thinking it was a weathered echinoid at first but it does not really look like it. Any idea?

Hello wonderful fossil-people! If you and you're gang enjoy solving a groovy mystery, I have a post for you! This rock was found in an area of Northern Arizona that is very well know for producing lots and lots of bryozoan, brachiopod, and crinoid fossils, as well as crystals and geodes. The bit of rock in question was found in the side of what appears to be a broken geode. There is a triangular fragment of stone that does not match the material surrounding it. There is also a white discoloration encompassing the triangle that I've highlighted in green on one of the photos below. The colors in the 3rd photo are a little more true to what it looks like in real life. The geode is kind of a pink-ish color and the triangle "fossil" is a dark brown/reddish color. Given the abundance of marine fossils found in the same location, I wonder if this is also fossil. It just seems so out of place in this rock. I have oodles of bryozoan, brachiopod, & crinoids that I've found in the same location and I can share pictures of these, if it somehow helps So what do you think, fossil or random bit of stone? If it is a fossil give me your best guess as to what it might be... or even give me your worst guess. I'm not picky lol.

Hey everyone. So I have recently been fossicking around Yass, NSW, Australia, and have come across a seemingly common formation in the Devonian group both in limestone and just shale and mudstone. It occurs alongside corals, and bivalves (in that case I'm assuming it's marine) and is sometimes in large colonies, such as the ones pictured, as well as independent from one another. Does anyone have any ideas as wo what this may be. Thanks in advance,

I found this oddity today while examining some fine grained finds. This is basically soft limestone, where the rock is pretty soft and most of the calcite has been dissolved. I forgot to include a scale, but if I were to guess, it's about 1/2" across the structure (12.7mm). I plan on measuring again. There were several of these throughout the piece, but this was the most prominent. My guess is some sort of Bryozoan.

Hi guys, I found this bone cluster on the shore of the Black Sea, near the city of Balchik, Bulgaria. From the region there have been findings of Miocene cetaceans, seals and some ground megafauna. The more circular bone somewhat reminds me of an ear bone but comparing it with pictures of fossil dolphin ear bones I can't say if it really is one. So my question is if it is an ear bone and if it is, does that mean that´s a part of a skull? Any help on the identification of the fossil will be very much appreciated! Best regards!

Hi again, hoping this time I have something. From Big Brook, NJ. I cannot find anything like it on extensive research. It's not modern bone. Sorry for the US quarter as I have temp misplaced my tape measure. The black smooth area on the top in the first pic is concave but not uniformly so. In one of the photos I put a pebble in there to try to show some depth it its not noticeable. Thanks again for any help!

This piece of arkosic sandstone from the late Eocene Coldwater formation north of Santa Paula, CA, has a few marine species traces. It would be great if anyone could ID the bivalves, but what really seems different is the set of chevrons I've pointed to in the top photo. Maybe it's just two bivalves wedged together to look like one? Appreciate the help!

From the album: Delaware Fossils
Two Exogyra cancellata shells from the Cretaceous spoils of Reedy Point, Delaware. Although Exogyras typically detached themselves from their anchorage while still very small - about 2-3 cm - these two animals continued to live and grow together. The lower valve is about 10 cm on the long axis. -
Found this mineralized bone at Big Brook Nj and on researching it, it looks very similar to photos of both Plesiosaur and Mosasaur vertebrae. About 1-3/4" long. Any help greatly appreciated!

Hello everyone and thanks ahead of time for any help you can give me. I've researched this fossil I found in Big Brook NJ extensively and cannot find anything listed like it or close to anything I've seen anyone find. It's about 3/4" and completely cone shaped. Not flat on any side. The lines do not appear to spiral. Any help greatly appreciated!!

Hello, I have this tooth for a few years and I have some doubts in the right ID. Its from a Miocene (Burdigalian) formation in Portugal. Size - 4cm. I assume it's from a marine mammal right? But which species? Best Regards Vieira

Hello, I am a newbie here and hoping to get some help IDing some what I believe to be fossils I found at Murdock and the Twin Rivers beaches (both are along the strait of Juan de Fuca coastline). These beaches are well known for having lots of concretion fossils. From what I’ve heard lot of sand shrimp, clams, and sometimes even whale or other mammal bones. Pic 1 &2:I think this giant rock is a fossilized whale vertebrae... I had one other person who is a fossil expert say that but looking for second opinions. Pic 3: Smaller fossilized bone? Pic 4 &6: my biggest interesting mystery!! Is this fossilized kelp, Crinoid or something else???? Pic 5& 9: curious what the cylinder long fossils are... many of them are hollow in the middle and have calcite/quartz crystals inside. I read another persons post about those strange tubes possibly being burrow tubes for mud shrimp. I originally thought crinoid stems or kelp tubes. Thoughts? Pic 7: Just a nice example of a concretion with a claw (crab or shrimp) round in this area Pic 8: Sea slug? I have no idea... Pic 10 & 11: Again I am wondering if it is a bone (my initial reaction) or if it’s fossilized kelp? Thoughts? Thank you for any help you can provide! I am teaching my sons who I homeschool along with myself as we get more into rockhounding and fossil hunting! -Holly

Could someone recommend a good reference book on prehistoric reptiles? I'm hoping for something along the lines of The Princeton Field Guide to Dinosaurs. Specifically, I want to be able to see and research a particular animal when it is mentioned. Thanks in advance. Tom

Hello all, Some photo's of my recent fossil hunting trips in the Netherlands (Limburg). All fossils are 73-66 and/or 73-69 million years old (late late Campanian, early Maastrichtien). Mainly belemnites (belemnitella and belemnella sp.), 3 sea urchin genus Echinocorys sp. (my girlfriends top find), one horse tooth (Equus sp.) a pipe and a bone (don't know species). Also on the first photo one trace fossil (ghost shrimp/crab) and one belemnite with holes. Kind regards, Fossilsforever

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.

Unearthed in North San Antonio Texas. These are a few pictures of the larger turtle "head". I'll post a picture of where I found it and the surrounding area and "rocks"

Uncovered in North San Antonio Texas in an area I believe to have been under water that had an abundance of marine life. This is an assumed "head" I unearthed. This is a picture of the left and right side. I previously posted some assumed "flippers". I want to know what you guys think. Thanks for your time.

Uncovered in North San Antonio Texas in an area I believe to have been under water at some point and had an abundance of marine life. These appear to be back flippers of different shapes and sizes. The largest one being 14.5 inches. This suggests a rather large creature. I'm thinking marine turtles. . I will post the " flippers" first. I will post what I believe to be the heads of these turtles next. The largest having a circumference of 27 inches.
