    An interesting rock

    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
  2. 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 !
  3. 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!

    11cm and 15cm hollow round rock

    Found 20+ intact spheres of various sizes, only broke open 2 with a 3lb sledge, the smaller one was empty, however the larger on had a 6 cm solid muddy form inside. That has since broke apart.

    Please help ID this fossil

    Any help identifying this rock fossil found at construction site near Dallas texas by a friend would be appreciated. My husband gave his friend $50 for it. I am a novice rock collector . Thank you for your assistance !

    ID Help Please

    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

    Concretion? Brachiopod?

    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

    fossil or concretion

    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.

    Hello trying to ID - concretion?

    Hello Probably concretion but seeking a second opinion. Thanks!

    Dino eggs or something else?

    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 f

    Amonite or concretion

    Hi, is this an amonite or part of a concretion sphere? I’m not sure where it was found. Many thanks

    Is it an Easter egg? On concretion?

    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!

    No clue, but interesting

    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 l
  14. Need some ID help on this one. Eocene, Keasey Formation, and an inclusion or something inside a concretion. Size of the whole piece is 12 x 15 cm, weighs about 6 pounds. Image 1 - Mollusk on top of something that has included into the matrix #2 is a close up of the mollusk and surrounding area Closeup of the inclusion material More images to follow.

    What is this?

    I found this at a house I am flipping. It is located on a hilltop of the desert with a wash on either side descending to a riverbed. There is a quarry along the riverbed where I get stone for landscaping, That stone is jagged and is colored orange-rust and white. This egg-shaped rock or specimen, however, is perfectly smooth with gray and plum coloration with a distinctive dark pattern and light spots. It is approximately 6 inches long. What do you think?

    Let's think outside the box

    Been looking at this and trying to decide how to approach it. Have at it. I can do close ups on the flats, but not the radius of the, dare I say, shell.
