Hey there! This is my first post on The Fossil Forum. I don't have a lot of knowledge about fossils, but I sure do know how to find them. Hopefully these aren't too obvious and boring, but I'm incredibly curious anyway. I found these near Sheep Bridge north of Phoenix, Arizona. Here the Verde river has cut through deep layers of ancient lava, sandstone, mudstone, etc. I was exploring for crystals up on a steep hill along the river's canyon walls when I came across a whole lot of these things. They are very fragile and I didn't want to break apart some of the 2-3 foot wide boulders of them so as to preserve them for others to find. Anyway, my understanding is that this area was once a sea floor, so I'm assuming they are some type of coral, anemone or something similar. The fossils are composed mostly of the same sediment which encases them, so I suppose they must be trace fossils, but please correct me if I am wrong. Other not-so-filled-in ones even had crystals and other minerals lining the cavity. As well, I looked at a geological map of Arizona and the area I was exploring is composed of the following... Late to Middle Miocene Basaltic Rocks (8-16 Ma): Mostly dark, mesa-forming basalt deposited as lava flows. Pliocene to Middle Miocene Deposits (2-16 Ma): Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. There are a couple photos of some ball shaped objects which were very easy to knock apart from the surrounding stone. I have no idea what those could be. The rest of the photos are of the coral looking objects. Some of them, if still intact, were nearly 24 inches long, but I left those behind and only took smaller samples. Please note how the "head" of the corals appears to flare out and is larger than the rest of the stem. Finally, some of them appear to have a little node sticking out of the "head," but I suspect that may be due to weathering as these are very fragile fossils. Thank you all so much for your interest and help and I look forward to learning more!

Hello, can anyone please help me with this Barnacle. Is this old? Do you have any idea of the age of this or if a fossil even or just a dead barnacle shell. Its about 2 inches the shell its self and about 1 1/2 depth. It was found in Oregon, United States (Pacific Ocean Beach)

Hi! I found this piece of sandstone in South Wales last week. Are they ammonites?
-
Found this piece of sandstone in Sullivan Co., PA. It comes from either the Huntley Mtn. Fm. (Mississippian/Devonian) or the Burgoon Ss. (Mississippian). What could have made these concentric rings? They go through the rock perpendicular to bedding. It's odd that the center is mostly round but further out is more square. Could it be a tree fossil? That is the only thing I can think of.

Hello everyone, I have a question regarding stabilising sandstone to keep it from crumbling. Last year I found and extracted a dinosaur footprint from a block on the beach at Whitby, Yorkshire UK. The footprint is of an Aalenian age therapod from approximately 170 million years ago. The print itself measures 20cm from the base to the tip of the centre claw mark. I am hoping to get the block it is in cut down into a slab in order to frame it but now that it is dry the sandstone is very loose and crumbly. I am looking for something that will add strength to the stone and prevent crumbling without significantly changing the colour of the stone or adding a shiny finish as I would like the finished piece to remain as close as possible to how it was, just stronger. I was hoping somebody would have an idea what would be best to soak the block with in order to keep it from falling apart. Any and all suggestions are greatly appreciated. Thank you, Benton Walters

Hello All! I am new here, recommended to visit this site, for help Identifying what I found, by someone named The Fossil Guy, who I found on Facebook by following the site Fossilera. My name is Hollie and I am from Long Island, New York. The object in question that I need help identifying was found by myself about ten years ago on the north shore of Long Island in a town called Lloyd Harbor and on the beach. Long Island was formed by a glacier 13,000 ago and is a terminal moraine. The north shore beaches are very rocky with large glacial rocks everywhere and the south shore beaches are all sand. I was told by the fossil guy that my piece is an imprint of a mollusk or worm in sandstone. I am hopeful you all can give me an idea to what it may be. Thank you and happy holidays!!

Found in Tuscarawas county, Ohio, USA. I found along a shallow stream bed that cuts deeply through a rocky gorge. Nearby is a large fossilized tree branch and I have found other Fossil there as well. The material is sandstone and I noticed it's starting to deteriorate. The size of the overall specimen is 152 mm in length.

I found a few of these fossils the other day and cant figure out what it is. Let me know your thoughts. The triangle is flat and you can see corners poking out when looked at from different angles.

Please tell me those are fish!!! (One of my dream find fossils)Found this near downtown Lockhart believe it or not, I’m a little protective over the spot cuz I COULD get super specific on this one and it’s not very off the beaten path ...lol

Greetings, everyone. I spent the other day on the east side of Ventura County breaking open sedimentary rocks. I'm not experienced enough with that sort of material to positively ID it but I think it was siltstone. There was a leaf and something else on both sides of one of the rocks. I've been having a hard time figuring out what the "something else" is. It measures about 35 by 14 millimeters. I took a few pictures of both sides under different lighting conditions to help bring out some of the finer details. It comes from the Modelo Formation (Miocene). Thanks ahead of time for any help in figuring out what it is. Here are pictures of the first side: Some pictures of the second side:

I found this sandstone slab on our property in south west Colorado, near Placerville, and was struck by the spider like creature especially. There also seems to be a mollusk nearby this creature. But its legs would have been so fragile, hard to imagine how it could be a fossil. But it doesn't seem like just a random shape to me. Any thoughts? I had to reduce the pictures quite a bit to fit size requirements here.

Hi I am needing help with identifying my fossil that I have found in Uneeda, which is located in Boone County West Virginia. This is my first try at this so be patient with me please. I've just took an interest in fossils about six months ago . Please help. Thanks!!!!

Found these imprints in the island of Rhodes (Greece). The age of the cediment according to geological maps of the area is upper Pliocene to lower Pleistocene. The units on the scale are cm. I wonder if my assumptions about pine cones are correct (even considered cycad cones) having read about pine cone specimens being found on the island. Would be really happy if someone could pinpoint the species from the shape of indentations - in the first image which is the most detailed there appears to be a small hole in the center of what I suppose are the cone scales. This can also be seen in the second image, though the structure is in worse shape probably due to being exposed for a long time.

There may be soft tissue you can't see in that "dud" concretion
winnph posted a topic in General Fossil Discussion
This is a really interesting article on imaging techniques used on concretions: https://www.palaeontologyonline.com/articles/2013/patterns-in-palaeontology-exceptional-preservation-of-fossils-in-concretions/- 5 replies

I set my 8 year old to work with a rubber mallet and old screwdriver on a landscape boulder in a SE Seattle neighborhood where the bedrock is the Blakeley formation, and where the homeowner was pretty sure their boulders were local bedrock. This was his favorite find, I said it looks like a bit of leaf/seed pod/wood to me. Anyone have thoughts about what it is? It measures almost exactly 1.0 cm x 0.5 cm.

This round concretion was given to me. It was found in Garland Texas in some woods. I have tried to ID the type of starfish but it split when I cracked open the concretion. There looks to be parts of more than one here as there are too many legs for one. I'm thinking the lighter spot of crystals is one that didn't form properly or the crystals destroyed the body. Also there is a tiny hole that looks like that was how the minerals replaced the bodies after they died. Well all 3 are in now thanks to Kane. The 3rd one is lower down. Thank you.

Red Flag on "Medusoid" fossils from the Ediacaran of Namibia
connorp posted a topic in Is It Real? How to Recognize Fossil Fabrications
For those interested in Ediacaran fossils, you may have seen a lot of supposed medusoids coming out of sandstones/quartzites in Namibia. They are usually labeled as unidentified medusoids, but sometimes as the enigmatic genus Namacalathus to command a higher price. At first glance, some specimens do bear resemblance to a top-down cross section of Namacalathus (such as the specimen below), however note that Namacalathus are preserved as calcite skeletons, not as molds in sandstone. A thread discussing these was posted several years ago, without a definitive conclusion. As far as I can find, there have been no published articles on these so called fossils, and perhaps rightly so. After a recent trip to the Field Museum, I am fairly confident that all of these specimens are simply the result of weathering in sandstone. Here is the specimen at the Field Museum that piqued my interest. A quick scan of our favorite auction site will reveal a number of nearly identical specimens listed as medusoid fossils. These holes are likely what are known as tafoni, defined by Wikipedia as "small (less than 1 cm (0.39 in)) to large (greater than 1 meter (3.3 ft)) cave-like features that develop in either natural or manmade, vertical to steeply sloping, exposures of granular rock (i.e., granite, sandstone) with smooth concave walls, and often round rims and openings." They have various methods of formation, but the more "Namacalathus"-looking specimens look (at least to me) to be the result of iron nodules rusting out. They may also be several tafoni that overlapped. Here is an image of tafoni in sandstone from Namibia. (image credit Wikipedia) Regardless of the exact process of formation, I am confident in saying that these are not fossils. There are plenty of other Ediacaran fossils out there for purchase, and given the high price tag these pseudofossils seem to command, I hope this post helps collectors avoid wasting money.

from Brazos River west of Houston Texas in a sandstone cast? I am not holding my breath on this one could this be a partial track?
-
I found this fossil a few weeks ago. It was in a creek bed that flows during the wet season but has pools in the dry. I know the creek has sandstone, but it also looks like it has limestone and possibly slate. There is also a lot of rocks containing rust. This fossil appears to be stained with it. I am located in Western Kentucky near Hopkinsville. One side looks like it is ribs. The other side is smooth and one part is unusually round. There are pockets that appear to be filled with sediment that has solidified into rock. I've added pictures from all sides and others with measurements. I will add them as replies since the files are too large. I wish I had more, but this is all I have.

Cheboygan Michigan they look like brains, I find them from baseball to basketball sizes. I broke one up with a sledge hammer, the center gets more dense. The out side seems to house shells?
