Found this small oddity while breaking apart limestone. The pitted appearance was interesting. The pits also seem to extend the whole way through. They also appear to wrap at a 90 degree angle on the side that isn't broken. The broken side reveals how they go through. I chipped away a little at the matrix, but didn't go too tough to keep from breaking it. Whole specimen with scale: (stacked photo) Showing outside 90 degree wrapped edge with same appearance: (stacked photo) Broken edge showing channels going through the width. Ad

I acquired these two slices of something from a rockhound couple in our club. They could not remember what they are or where they came from, but they could be from Arizona or somewhere in the Southwest US as they spend their winters in Arizona and always come back with stuff from collecting and wheeling and dealing down there. The bigger piece especially looks like oncolites to me, but I have been fooled before. Does anyone recognize either of these, and more importantly where they might be from? (If I can figure out the location I'll have a better chance of tracking down the ID/age.)

So I’m at a point where I think it’d be best to just show you the entire thing that I’m currently looking at, aside from the tons of pieces that I’ve set aside all around this pit I’ve got now. I don’t expect this to sway anyones opinions but it’s very likely the last post I’m going to leave until I can finish cleaning around the edges of it—whatever it is, or isn’t, potentially. So I guess I’m asking now, is this also typical for limestone? Again, I’m on the far northwest edge of San Antonio, pretty much on the helotes hill country city limit—just a couple of miles east from government canyon

Construction site in Prosper, TX. The only rocks of good size in the native site soil are these big limestone nodules. I think they are cephalopods. Thoughts? Thx, fowells

Jurassic/Cretaceous fossils? (sponge/bryozoan/crinoid)
IsaacTheFossilMan posted a topic in Fossil ID
My better half has just rediscovered some of her old fossils from years ago - as such, she does not know the provenance, though based on the matrix and preservation, I believe them to be Cotswoldian in origin - Jurassic, Inferior/Greater Oolite. These two in particular absolutely had us stumped - This is number one - I originally thought disarticulated crinoid, but the 'branching' pattern in picture 2 threw me off a lot, going to bryozoans and all sorts, bouncing around til' I decided, maybe, not a fossil? But then again, it displays the glow from calcite: -

Mud fossil from large cluster formation of limestone seem like is a blade of grass growing on to see pictures
Austin2000 posted a topic in Fossil ID
I'm not joking about this but these these I thought were like regular fossils I picked them up and they like they didn't feel right I had gloves on rubber gloves you know the ones workman's gloves and if I put them in a different bag and when I got home I picked them up and I put them in water the vinegar and stuff and they got like really slimy and I just put them on the side and I got him in the steel Tupperware container and another tupperware container with muriatic acid and the other one you know so in case they do get out whatever I don't know I know it sounds funny but it is what it is -
A friend asked me to look at this fossil he discovered at the base of a limestone bluff in NE Iowa it is a Native American winter camp and cave complex. Have found trilobite and marine fossils in the area. It looks remarkably like a tall molar or short bone but a couple hundred million years too old. Does anybody recognize this? My best guess is that is a stalk of a plant precursor?

Fossils from Magoito, Portugal (Cretaceous limestone cliffs)
tobie-lisbon93 posted a topic in Fossil ID
First trip fossil hunting. Mix of vertibrate fossil, unidentified trace fossils, and pretty rocks (hard to tell from from the photo). Second batch is from Caparica, Miocene, including shark teeth (probably maku). Anyone want to help ID some? -

Hi. Everyone thanks. Need some advice on some large 40+ lb clusters of fossilferious agate

Hello everyone and thank you for letting me join the forum I believe I had joined before and I couldn't find my account for some reason it's been some years so I guess it got deleted and also I'm using my phone because back in January the apartment building I lived in burnt down and I'm staying at this motel which happens to be on a gold mine for fossils Well my question is this on the formations of the fossils in the limestone mainly the hotter limestone which is probably the older one like the green and the greenish blue and the gray I have several large pieces that look like the -
Found this in the rocks used to repair our road. Larger and narrower than any of the brachiopods I've found so far. Is it even a brachiopod at all? I assume the rock originated in the same formation as what I've found around the railroad tracks and in my driveway gravel, which I've been told came from the Slade Formation (Mississippian).

Found in little creek around town, late Ordovician period in Southern Ontario, absolutely stumped on what it is. Any ideas are welcome, thanks in advance! Sorry for the low quality photos, these are the best I could get, fossil is 1cm (Long) with little groves.

This is perfectly circular in cross section. I am fairly sure this is a Tentaculitoid, but I've never really identified one before. These are somewhat rare where I fossil hunt. I've seen a few bits and pieces stuffed inside of gastropod shells. This one was fairly long, with at least another 1 cm of material broken off when I cut it out of the parent rock. It is mostly white in color, but that is more shell preservation at this site rather than an important attribute. Most of the Tentaculitoids in books I've seen have ribbed ornament, whereas this has lengthwise ribs. C

Could someone help with I'd please? I found 2 of these balls weighing about 64 grams and a little larger in the wooded area on my property in Kentucky, buried and sticking up about half out of ground. I had to heat with butane 12 times and drop into ice water to even crack one. there are sparkly spots you can barely see inside of the one. Any help would be appreciated.

Hello. this one I found as part of fill on a dirt road in Illinois near the Mazon Creek area as I was looking for concretions. Part of the fossil was covered by a "hood" of limestone that I ground off with my dremel tool. I think this actually saved it from being really torn up on the road.

Hi all, I found this chalcedony geode on the Nordmany coastline. After later inspection i found these 'stalks' all over the geode, i assume it's a plant fossil. Could anybody tell me exactly what it is? They are quite small, the one in the second picture is 1 cm long. Thanks in advance!

Solnhofen Dragonfly - What is real?
DarasFossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, My Dad and I purchased a really beautiful Solnhofen dragonfly resembling something very similar to this (not my picture), which has these really prominent eyes and legs on it. Is this naturally preserved or likely painted on, and if so, does this affect the quality and value? Seller is reputable and I know paint is common with the Solnhofen just so you can see them for display which I don't mind but just curious what is likely real and what is not... Ours is a big boy at over 7". -
Howdy! I found a beautiful pseudorthoceras last week and last night I noticed a tiny white organism on the rock. It looks like several "Vs" strung together. Fossil is 0.5 cm, is from the Glenshaw Formation and likely Brush Creek Limestone. I have no idea what this thing is. Thanks for the help.

Found this fossil in Co. Dublin, Ireland. According to my research it belongs to the genus merocanites, and if that is correct it seems to be rare-ish? Can anyone confirm? Thanks!
