I found this long cylinder sticking out of the creek wall few weeks ago. I had no choice , but to break it from the rock. Ended up in several pieces. I'm not quiet sure 100 percent what this is. I searched the forum, but can't figure out other than Rudist.

I have come across several tiny bivalves and gastropods while digging marine fossils out of sandstone boulders, they range in size from about less than 1mm to about 10mm. I was wondering, do all of these small specimen grow into the larger ones? Also, I can plenty photos of present day small specimen but I can not seem to find many photos of prehistoric small bivalves and gastropods, anyone have any links to tiny prehistoric shells???

These things are very small and difficult to find but I came across a stone that was littered with hundreds of forams and these spicules. I don't recall seeing anything that look like a sponge so I'm very curious as to why there were so many of these spicules being found in this stone that was found in a desert.

Sieved through some matrix the other day and found this little specimen that I thought worth sharing. The scale is in .5 mm so specimen is 4 mm long so fairly small This is a toe bone from a bird about 100 million years old. It is unusual but the bias towards toe bones from this area is high go figure. The matrix this came out of is marine. Enjoy Mike

Have been prepping out a few bits and pieces encased in matrix to see if anything interesting. This is from the Toolebuc formation in Central Queensland Australia. The formation is Albian about 100 million years old. My best guess is this is a skull piece (partial quadrate) the bit the jaw hinges on from a marine reptile. There appears to be three teeth socket points looking at what I assume to be the bottom. The problem with that idea is they are only 5 to 10 mm deep and too close to the hinge point. The specimen is only a partial bone but hoping complete enough for someone to recognise to the general species from photos. Thanks for all feedback in advance. I may need to retake some photos from slightly different angles. Mike

Just wondering if this is a fossil and of it is, what do you think it might be? Sorry I didn't have a ruler when taking pics. My thumb is on the pics and it's about an inch or a little less across. This was found in a limestone riverbed near Justin, Texas (North Central Texas). We have found many other smaller marine fossils (actually casts I think - I am not an expert by any means) that I am pretty sure are from the Cretaceous Period in the same area. I have more pictures that are higher resolution, but I can't upload them here due to the size restrictions. Thanks in advance for any info or ideas that you might have.

Greetings fellow fossil enthusiasts! I don't know what this thing is. I've shown it to several other fossil guys in Houston and they don't know what it is either. I think it's from a fish of some sort, other than that I have no idea. I found it in Hogtown Creek in Gainesville so it's probably Late Miocene-Pliocene. Scale bar is in Millimeters. Any help is greatly appreciated.

I found this in southern Indiana. It is from the Ordovician period (Dillsboro formation). I initially grabbed this for the mollusk located in the bottom right corner (it is a mollusk, right?), but am more curious about the thing jutting out of the left. Is this just a concretion? Any help would be appreciated.

I took a trip to Southern Indiana to do some fossil hunting (they are an elusive creature). I am now just cleaning some of them up and saw this one and it piqued my curiosity. It is from the Ordovician period (Dillsboro formation). Can anyone help me out? Sorry for the use of a quarter, it was all I had. Thank you.

Hello everyone! I am back to ask for opinions again on an unusual find in north eastern indiana. It has a few different things going on and i will do my best to take decent pictures for you to see. First let me say the rock in its entirety is around 3 inch (76 mm) in length. 1 inch (25 mm) tall and 2.5 inches (63 mm) wide. The "teeth" are roughly 1/4 inch wide.

Found very little yesterday. This is somewhat unique as are all earbones. Found in a Bone Valley area with no Pleistocene material but with pre_equus horse teeth. At first, I thought "baleen whale", but it is too small. Asking @Harry Pristis and @Boesse to evaluate, but encourage all comments and suggestions. Jack

Hello, so next week i will be o vacation on an island in Greece and i was wondering if its possible to find shark teeth there and how to, i dont know a lot about searching for fossils and if sharks lived there to create them in the first place but i am willing to try so if you could suggest places that fossils could possibly be found like specific places in beaches, mountains or anything you have in mind i would be really thankful. Thanks

I'm sure that the one long fossil is part of a crab leg but I can't seem to find anything on the web like it, all of the crab fossils I find appear to be your typical size crab such as the blue crab. This look like it would come from a very large crab. Came across what looked like other leg parts that appeared to be at least 6-8 inches. That second smaller piece, I don't have a clue. There's not much there to go on, just hoping that maybe someone will recognize the pattern on it and know what it belongs to. These were dug out of sandstone in which the bivalves and gastropods have been dated to about 2.5 million years old.

I came across these while digging bivalves and gastropods out of sandstone boulders. They look like some sort of worm-like specimen sitting on top of what appears to be a large snail fossil. I can't seem to find photos of anything that looks like these. Just hoping someone out there might know for sure what these are. Thanks

Hi, I'm new to fossil hunting and found some of these at Beltzville State Park on the lake bank in Pennsylvania. They are from the Devonian Period. I've looked on the state website but can't seem to find anything specific that resembles this one. I found one picture by chance online of someone that had something resembling it and they said it was a Rugose Coral Mold. Does anyone know that to be? Thanks in advance for any help!!

Dug this small fossil out of a sandstone boulder that was littered with bivalves and gastropod. A lot of the fossils found in the sandstone date back to the Pliocene so I can only assume it is from that period also. Thanks

Good afternoon (for those in EST), I found this while hunting for marine fossils and was wondering if someone could identify this for me. This was found in South Bend Indiana and is approximately 9cm long. It doesn't look like the typical crinoid or sponge to me. Whatever it is, it doesn't seem to be very rare as I found a lot of these. It could be geologic but something about the way it is laid out makes me think otherwise. Thank you for your help.

I have read that land worm fossil are extremely rare but how about marine worm fossils? Are marine worm fossils as rare as land worms and has anyone every seen photos or heard of a marine worm that might have a calcium-like outer shell?? Thanks

Recently I’ve found some strange fossils from an area in Simi Valley (Southern California). I had thought there were only shells, but turns out there is vertebrate material! Among other fragments, I found a couple big whale vertebrae as well as this piece here that I am unsure about. I’ve seen some mentions of fossils from smaller marine mammals like dolphins and pinnipeds, maybe it’s one of those? Unfortunately there only one end present, so I’m not expecting to get anything too specific. The formation is about 5 million to 11 thousand years more. Hopefully I can get some more interesting things from that spot. Thanks!

Here is a limestone reef rock from Tucki Mountain in Death Valley. The strata is vertical. There was a band of reef rock several hundred feet across. Lots of crinoids but it's the sponge / archaeocyathan fossils that I'd like to know about. This is the first time I've done this, so I'm not sure how the answers arrive... Thanks very much! Dick

This piece was found at the Del Mar Formation in San Diego. It looks like there might be a bone in the middle (see close up). I’m a complete novice at this, so any information is valuable. Do you think it might be bone?

Hi, here is a bunch of tiny beauties from Texas (Lake Bridgeport). If somebody can help ID the gastropods at 1:40 and a crinoid at 4:20, it would be much appreciated.

Found on a parking lot in southern Poland. The flints in the area can be either Late Jurassic or Late Cretaceous-Paleogene in age. The most common fossils are sponges, but ichnofossils, brachiopods, bivalves, echinoids, bryozoans and dasyclads also occur. Any idea on this one?

Hi all I found this at Post Oak Creek in Sherman, TX, this weekend. I'm unsure of what it is--maybe part of a crustacean (quarter for reference). There are two "sockets" on either side of the flat portion. Any help with an ID would be much appreciated (a fossilized shrimp part has been floated). Thanks!
