From the album: Missouri Plant Fossils
Roughly 2.3 cm Long -
Yesterday: fossil hunting with my girlfriend in Limburg. Many Cretaceous limestones and good fossil specimens! Including a really big and complete Pycnodonte vesicularis (Lamarck, 1806). My second biggest Pycnodonte. Many belemnites (including a real cool black one!), two pieces (including a big one) from the same genus (Pycnodonte) and one sea urchin Echinocorys sp. or Echinocorys scutata (Leske, 1778). Also one recent cow/bovid tooth and a piece of vase. The two photo's on the right are from another (earlier) trip (fossils are on the ground in a field. Finds: one sea urchin Cardiaster granuloses (Goldfuss, 1829) and one belemnite (many more belemnites were found). Genus Belemnitella or Belemnella (Pachybelemnella) sp.)

Only one I've ever found like this. What it is exactly, I don't know. Found in a load of limestone road base, likely from a local mine.

From what I've learned crinoids aren't from around here, prob from way upstream fill rock. Here being Dallas creekbed in Eagle Ford shale. Its so unique with the patterns, almost looks carved, just guessing part of a crinoid because of the cylinder shape. What the heck is it?

Thanks beforehand. My young granddaughters (8 and 5 yo) have went fossil hunting in their backyard around Lake Cumberland in Kentucky and as I am not experienced in identification and cleaning techniques I appreciate all help given to identify several examples of what we collected.

Found this on gravel bank in creek close to DFW, in a narrow band of Alluvium smack dab in middle of Fluviatile terrace deposits. I'm not sure what to make of it, appreciate input!

This little thingy was in Mississippian Redwall limestone in central Arizona. It was in a section of the Redwall with very few other fossils. It's about 10mm long and 7mm wide. What do you think?

I'm looking for assistance identifying a large fossil that was in with skids of limestone rockery from the Niagara Escarpment. I have uploaded a series of pictures to Flickr https://flic.kr/s/aHsmTVvrFN and attached one image. It looks like a type of coral. There is lots of texture on the surface. When opened up, it is full of long columns. Thanks.

Hi, I hope this is ok to post! Whilst out on a walk we came across the attached fossil. Whilst I appreciate it doesn't seem much, its quite distinct and any help to identify it - and help educate the small hands which has been carefully cleaning it - would be very much appreciated. I might have some explaining to do that it isn't a t-rex We are located in Derbyshire, United Kingdom. If anybody has good references for teaching kids (6 year old and 3 year old) about fossils it would be great to have them.

Hi. Found among the huge limestone layer at the Caney River in central Washington County, northeastern Oklahoma. Pennsylvanian. It's a little closer to Kansas than to Tulsa. A few miles east of the Osage Hills (or Rolling Hills of the Osage, depending on the which map).

So, in trying to identify my local limestone for sure, I've gotten the need to try to extract conodonts, and I'd for sure like to see other microfossils. I know this has been discussed here before, but I was wondering what might be the correct or tried and tested method for home, using obtainable chemicals. The last thread I found was talking about lab processes and clouds of white smoke. I've heard different things from using acids (Vinegar), Hydrogen Peroxide (3% limit at Walmart), to Kerosene. Also a need for sieves, filters, etc. Curious for a guide or advice for effective home methods. - Clint

San Antonio, Tx I pulled up a piece of sediment from my yard and this came loose also. I have no idea what it is. I have another rock very similar but much larger.

Hello all, Im very new to this. Currently I'm in Czech Republic and some time ago i found my first interesting fossil in this area: https://www.google.com/maps/place/Český+kras+Protected+Landscape/@49.9290996,14.178056,13.17z/data=!4m5!3m4!1s0x470ba30d37e892c5:0xd582af42389f3a3b!8m2!3d49.9355334!4d14.1819469 I don't have any background in palaeontology and decided to get some help from enthusiasts with experience. It's one rock. The main Fossil on "top" is that Trilobites tail? What are those yellowish formations visible on the side of the rock? They stand out and have organic shapes. Are they bones?

From the album: Missouri Plant Fossils
When this came out of the earth I was shocked by how many were bundled together as I mostly find only fragmentary pieces of one specimen. The small limestone chunk on the left is a piece that came undone at the site I found this fossil at. More images of these fossils: https://imgur.com/a/KnjIeqG Correct id by Fossildude19 -
I'm having trouble learning about these fossils I'm finding!
Jared C posted a topic in General Fossil Discussion
Hi all! Perhaps this is a dumb question, but I' still new to the forum as well as the hobby itself, so I offer a teaching moment - In round rock, (just north of austin in central texas), I have a location at the base of a limestone cliff where after some gritty mining efforts I've come across an extremely dense pocket of what I've been informed are internal casts of rudists. That ID was great!, but I'm having trouble learning about what the actual organisms were like. I've tried researching quite a bit with no clear picture of what these are that I'm discovering. Also geologic maps of the area have some disagreement, so the exact spot could be Edwards limestone, eagle ford, or buda limestone. I understand (I think) that these were some variation of a mollusk but the story ends there. Discovering these would be even more magical if I had a proper understanding of what these organisms were like, looked like, and what role they played in their environment while they were living. I know these are a common fossil so many of you will have a wealth of knowledge about these. Please enlighten me, I'd love to learn! Below are some examples for reference:

Time Period: Pennsylvanian Location: Missouri Formation: Most likely Winterset limestone Hello! I am currently puzzled on weather or not this is a Conodont or some fragments from Brachiopod. I am thinking it could be broken parts of a shell or broken pieces of a Brachiopods fossilized lophophore supports from a very small specimen! I have not found any conodont specimens from this location yet as I usually do not hunt for them Images in natural file size: https://imgur.com/a/KNeqtZn

I found this in an area of North East China. The area has some volcanic history, and a lot of granite mines. I thought that I had it figured out, but am torn on what type of limestone it is, thus what era it could have formed during, thereby leaving me clueless about the small, potential fossil! Any help would be appreciated! Also, any clues on how the granite became fused to the limestone?

When cleaning up rocks I brought home today, I found this little piece that I didn't originally target. It's pentagon shape makes me believe it's for sure a fossil. I've never found anything like it, so I feel like I'm about to get an education here. Perhaps part of a crinoid? Whatever it is, I don't have the experience, yet. Also noticed the indented hole on the top. Maybe part of it, maybe not. It's way too centered I think to not be part of it. Underside. It is convex with a small raised ridge along the edge. Sideways view of the underside with scale: Front view with scale (non focus stacked) There is a porous layer on top, which is very similar to crinoids I've seen in the past. I've only ever found stems.

A firend of me sent me this pic of cobble stone he picked up on the seashore. The only thing I could tell are the gastropods. What else are there? Possible ID and age?

Me and my boyfriend went for a walk in the nearby Aristide and Silverdale area of outstanding natural beauty a few weeks ago. We are both at uni in Lancaster so have been enjoying walks in the Lake District and nearby. I wanted to visit Jack Scout as a dissertation topic I was thinking about was related to the local geology of the area. I was not expecting to find loose fossils, and was paying close attention to the limestone rocks and pavement for fossils in situ until my boyfriend came up with a ‘funny rock’ to check with me and lo and behold, an impromptu fossil hunt began. Nothing is of great quality and I have found it very hard to find much literature on the area so nothing is really identified. But it is a truly beautiful area and a fun walk. I believe these fossils are from the Park Limestone formation of Jack Scout, there is lots of Carboniferous limestone deposited around 325-360 MYA.

Can anyone help me identify these? The longest is 5 1/2”. Maybe deer antler pieces?

The photo shows several nodules embedded in Redwall Limestone (Mississippian) along highway 89a west of Jerome, Arizona. Also in this layer are crinoids, brachiopods and solitary rugose corals. I think I've read about these in the dim, dusty past, and I seem to recall that they are not fossils, but some other geological phenomenon. Any help?

Low-budget rock and fossil cutting/slicing/slabbing
FranzBernhard posted a topic in Fossil Preparation
Ok, I proved it possible to make polished slabs of substantial size (ca. 50 cm2) without any machine, purely by hand, in an acceptable time and of good quality and with things I already had, especially flat plates. Grinding and polishing media had to be bought, of course. All of this can be done on a desk in an apartment, no serious noise or dust production involved, just some sludge . Only one problem remains - you need an as flat as possible surface to start with. Such flat surfaces are usually produced with rock saws. For rock cutting, I have only experience with professional equipment. However, such rock saws are expensive, heavy, noisy etc. What are the low-cost options for the occasional saw cut? First, forget the angle grinder. Second, what about tile saws? They are cheap, around 50-60 Euro, and far less than that for a used one. Quite lightweight and portable, about 10 kg. But they are made for cutting thin tiles, maximum cutting depth is about 35 mm. I am used to "rotate" specimens on the saw blade, so this can be doubled (Attention, this rotation can be dangerous if not done properly and results also in a surface not as flat as you might desire!) I don´t have experience with a tile saw yet, has anybody of you? And has someone used such a saw in an apartment? Has anyone tried to make parallel cuts with such a saw? Other thing: What about cutting specimens already in the field? Has someone done this with low-cost equipment? Maybe you can use a tile saw with an DC/AC converter connected to your car? I think, that´s all what I like to know at the moment . Thank you! Franz Bernhard
