Hi all, A friend of mine found these in a quarry in Limburg, near Maastricht, many years ago. The exact location is unknown, but it was found in very bright, loose sand (maybe that rings a bell). I suspect they are concretions, but I am not sure. Any info and insights are welcome! Thanks!

I joined today just to figure out what I’ve found out back today. Found in Johnson County Missouri. Does also seem to be hollow as I can hear something shaking around inside. Is about 3” in diameter. Would greatly appreciate your thoughts!! Thank you all!

Texas Cretaceous: Nearly complete mummified body, or random concretion?
Kenna in Texas posted a topic in Fossil ID
Good morning, I hope this is interesting. I found what I suspect is the fossil of a reptile or dinosaur that was torn open and then mummified prior to fossilization. Knowing the odds of this are vanishingly small, I will let the photos speak for themselves. I see soft tissue structures that align with reptilian anatomy but your mileage may vary. This was found in Grayson county Texas just south of Lake Texarkana. Multiple rock groups are exposed in a small area here, including Denton Clay, Weno Limestone, & Grayson Marl, all of which are from the Cretaceous. Thanks in advance for any and all responses. Kenna PS: Some of you have posted some remarkable material for new members - guides to eggs, teeth, and how to post ID requests - amazing stuff. It is appreciated!- 11 replies

I went fossil hunting out near the nearby creek today, since i had some free time. Here’s what i found: while i’m sure this first one is a concretion, i wanna know what yall think! Here’s the second one, which interested me way more- first one is 5cm, second one is 9 and a half centimeters: if you look closely- you can see weird markings on the second fossil that look almost like a tire track. Let me know what yall think that is.

Before I get stoned to death for posting this here (lame pun intended)…let me just say that I honestly have no clue what I’m looking at here but I am not suggesting, nor am I of the mind—that it’s a fossil, but it was just so strange lookin’ that I couldn’t help my curiosity, so here I am asking for opinions on what caused this to form and what it’s composed of most likely (if anything other than limestone, that is…. (-__-). location- far nw San Antonio, tx , just outside the foothills of the hillcountry (helotes, tx) Again, I do want to apologize if this belongs in a strictly geological forum somewhere, I’d have probably posted it there instead, had I been aware of one existing which was similar to this platform but exclusively for weird ugly rock identification help (lol). Thanks in advance.

Hello all- im new here but have been following this group for a while now. Hoping you can help me figure out what this HEAVY rock/ fossil is? I found it on my property up here in Northern California. As mentioned above it is very heavy compared to rock that are similar in size. It also has no rough edges. Thanks in advance!!!

Good afternoon, This egg shaped rock was found on the surface of a reclaimed quarry in Alberta. Any thoughts on what it may be? Considering it was found at a gravel quarry my initial thoughts were that it was a rock that was somehow shaped during excavation and or screening. The colours and the jagged eggshell type patterns have me wondering though...? Apologies for the imperial measurements for scale. For reference the egg is approximately 90 mm (9cm) in length. Thanks for the help.

A friend found this stone west of the Missouri in SD. It's now in my possession. There's one very visible spiral shell and what I believe are fragments of more scattered throughout, plus some bonus crystalline spots and something funky going on next to them (pic 4). I have no idea when it dates to, but another rock found nearby is probably Ordovician. However, according to the friend, they were all deposited there by the river more recently and were near the surface, so context is pretty lacking. As you can see, the rock itself is pretty weird too, especially on the back. Answers to any of my questions (what the fossils are, how old it is, what is going on with the rock) would be greatly appreciated. Thanks!

Currently excavating my backyard. We're digging through about 2m of rock (yes it's very expensive lol). I went outside to have a look at the rock and see if I spotted anything interesting. I'm currently studying paleontology/geology at Uni. Anyway I was wondering what people thought of this. It's colour pattern and shape drew me to have a closer look. Am I looking at a concretion? Something else? Just curious. The rocks will be removed and broken up in a few days so last chance to see if anything interesting in them. Found in the Hunter Valley NSW Australia. The area is known for Permian rocks/fossils, though the sites are about 15 minute drives from here. Thanks

Another piece found in the badlands of Alberta. Could it be a cactus ? Or just a interesting looking concretion? Any help identifying much appreciated. Thanks !

Hi guys, Today I have questions about my 2 rocks. They were found somewhere between Coonamble NSW Australia and Darwin NT Australia only about 3400kms so gosh knows the geological information my thoughts are I most likely picked them up between either Mt ISA and Winton Queensland or Katherine and Darwin NT but it was about 12yrs ago so I really can't remember what came from where except 3 other "special" ones that I can't locate at the moment because obviously I put them "somewhere very safe" First rock is pale grey and contains heaps of little quartz type crystals I don't really know what else to say other than should I crack it open? Second rock is more interesting to me as it is a harder rock encased in a calcite type material with a couple of little crystals in both hard and softer rock, my question on this one is should I try to dig a little deeper through the calcite material and see what the harder rock actually looks like? Kind regards Tara

Yankeetown, Fl. find: Peanut shaped object. Double concretion?
Shirley Fireball posted a topic in Fossil ID
While I was looking for sea biscuits in Yankeetown, I found this. At first I thought it was an actual peanut. Lol I tried doing some research on it but can't really find that much information about what it actually is. So I'm hoping y'all will have some more suggestions or details. The closest I've found online is it being a double concretion. It's relatively small compared to similar ones I've found online. It's a little over 3cm long and less than 2cm wide. Not magnetic. Thank you for any and all help!- 3 replies

Picked up the below a few months ago. Initially I thought it may just be a concretion. After a second look I noticed holes on the stem portion that reminded me of a prior find. The old find, rare for Florida, was an extinct baleen whale ear bone (Parioetobalaena). While I don't see this as an exact match I thought it was worthy of posting and seeking additional opinions. I am hoping Dr Boessenecker @Boesse will have time to take a look and comment. The specimen measures - 30mm x 36mm x 23mm Or in inches = 1 3/8" x 1 1/2" x 7/8" The blue ruler in the photos is mm and the pink inches.

Hello, I recently found this, (Cretaceous). I think it is a small concretion of a very curious shape, but because of its shape, it also makes me think of an internal brachiopod mold. What do you think ? @Tidgy's Dad

I found this in eastern Montana in a wash bed. There were many concretion looks different, irregular surface on top and it is a continuous spiral from top to bottom. Almost looks like poop (coprolite) but it is heavy. How would you go about looking at its interior? Hammer? Scribe? I know people split some of them but I have neve done that.

Hi everyone. I would like your opinion of if this is a dinosaur egg or something else, like a Concretion. I found it several years ago about an hour south of Williston North Dakota. I know the area is known for having cannon ball Concretions but it is also known for an area rich with fossils and petrified wood. I have spent countless hours researching and looking through photos of both Dino eggs and Concretions etc. but have never found anything that looks exactly like this. The closest looking thing I have found to it was actually Dino eggs in the natural history museum in New York. I found it near a clay deposit, there were three groups of the egg like formations. Total number of all of them were about 18-34 (it’s been a long time soon don’t recall exactly how many but I only took one). Most of them were cracked all around (like a mosaic) and this one was in the best shape. Also it had what I believe to be clay surrounding the outside which we chipped off to reveal this (we didn’t know what we were doing, and the thought it might be an actual Dino egg at first was unbelievable). Also it’s very heavy. I’ve gone back and forth over the years if it is a Dino egg or not and would love y’all’s opinion. Am happy to take more photos upon request. I am new to the community, happy to be apart of it and looking forward to any response. Thanks again Shane

My friend found this egg in Ventura County, California (in the United States) about 20-25 years ago. She said the missing outer piece just happened this year. She doesn't know what happened or who broke it. I tried to look up photos of fossilized eggs, but none looked right. It *could* be a concretion, but I'm no geologist. Any idea? It's roughly 8 inches long and a tad over 5 inches wide at its widest point. Thank you!

New to the forum and I've had this for about a year now and thought I'd toss it out there to see if anyone else finds it interesting. Unfortunately I don't have a lot of info on this. I found it at an estate sale and it was fairly low price so I thought I'd take a risk and grab it because I've never seen anything like it. Was told the owner originally got it in a shop in Utah and was told it was an egg. It had been in a fire (you can see scorch marks on the top, where there looks to be the spine) but pretty well intact. I don't see any obvious hard shell but I do notice flaking of what looks like sedimentary layers on the back side so I think it might be a concretion. Either way thought it was interesting and maybe I am just seeing things but one part sure looks like a rib cage
