  1. I live in north central NM on the continental divide. Is it possible that there is an actual bone covered with sand sticking out of this sandstone?
  2. Maybe some type of Brachiopod, or Coral
  3. From the album WhodamanHD's Fossil collection.

    Ammonite, other than that i don't know anything about this one, I don't even remember where I got it.

    I removed a mosasaur tooth from this. Bought at a fossil store. Various bone, identity unknown unless it is associated with the mosasaur tooth.
  6. I found a really cool Calamites fossil with exquisite detail on a wet day a couple months ago, but after a week or so of keeping it indoors, the details started to fade and the colors became dull. It springs back to life when damp, but that only lasts so long and I fear that annually applying water might eventually wear the fossil. I think I've read somewhere that you can use vegetable oil to keep rocks/fossils looking saturated, but I was wondering if that might cause any structural damage or any other ill effects to a sandstone-based fossil. Thanks!
  7. My father asked me to see if i could find out what this is. Is it just a natural formation or something else? This is the only picture he sent me but I can get him to send more if needed.
  8. I am new to fossils... I found this on the rocky shore of Cabrillo Beach, San Pedro, California. The rock is a hard sandstone. Any idea about the fossils?
  9. Hi everyone, My girlfriend and I were hiking near Red Rock Canyon in Southern Nevada yesterday and came across an interesting pattern of pronounced ridges in the rock. My first thought was that they are fossilized water ripples, which have been found in the park. But on one edge the ripples stop in a very clear tapered line, which seems out of place for a shore line. I wish we had put something in the photos to get a better scale of the pattern but you can see my knee and foot in one picture. We got hooked on fossil hunting about a year ago would love to find out more about this pattern. Thank you very much for your help. -- Aaron
  10. This is roughly 5', think there's anything in the middle perhaps? Gonzales TX
  11. Hi Folks, 2nd post. I came here to see if I could get a large fossil identified, but while I was taking pics I also snapped one of this weird, possible fossil that I suspect may be petrified wood. Here it is, sorry for my poor camera ability: This was found in some suburban greenspace area near Kansas City, MO. It has a very strong "linearity" to it, as if it was once a section of log. It might be petrified wood, but I'd not be surpirsed to find out that it isn't. For one, it has the linearity I mentioned, a definite orientation to the thing. But the details of this "grain" ar not as defined as I've seen on confirmed petrified wood. It is also suspiciously lightweight and soft, like sandstone, not very dense and hard as the other petrified wood I've seen. I'm taking the chance someone can recognize it. This last bonus item is not a fossil at all, definitely a shale-like rock, also found in KS, any one know what this is? It is strongly stratified, grey, with bronze flecks in it. The point you can see in the pic is of modern manufacture. Thanks for looking!
  12. Fossilized bone segment found in creek bed in NE Alabama... Found near sandstone and chert in a dry creek. Definitely turned to stone... Could drive a nail and also sounds like rock when tapped. Will also add pics of other side and both ends.
  13. Hello, I am new to the forum and seeking some information on what I have found. This was found yesterday in Manford, Oklahoma along the Arkansas River basin. It appears to be sandstone and several layers had fossil shells. I saw this in a newer layer than the shells are in and it appears to my untrained and ignorant eye to be a snake, a lizard, some kind of serpentine fish, etc... Can anyone shed some light on this for me? If you need any more information I will do my best. Thanks!!
  14. Hi This is scale fish ? Age:Oligocene ( Krośnieński sandstone ). Location: Carpathian mountain , Beskidy , Southern Poland. In this sandstone fragments outside the plant have not heard about fish. And this piece interested me.
  15. Hi, I need help identifying whether or not what I have is a positive cast of a fossil footprint. The "footprint" itself is about 5-6 inches long and maybe 3 inches across. The stone it is sitting on feels like a sandstone, but the "footprint" is very hard rock, definitely not sandstone. Thanks!
  16. Found this embedded in sandstone in Overton County, Tennessee. Does anyone know what it is? Thanks. -Dan
  17. Haven't been out to hunt much yet, but I am planning to go out this weekend. So far I know of four general animals found on my property from the Pierre shale (baculites, gastropods, muscles, and brachiopods or bivalves) I have also found some small chunks of petrified wood laying around. but i was wondering if anyone had advice for hunting the sandstone? I am aware of layers that have well preserved fossils here, but I haven't found a very good way of exposing them.
  18. Hi all, This is more of a geology question but the attached item is sandstone. I don't think sandstone is known for fossils-us it? Anyway the attached lines in the stone intrigue me. I was told these may be from a glacier. Someone said a plow but where it was found was never plowed but on a Native American site. Anyway , are these grooved fossils, glacial or man made such as abrading?
  19. Hi, Absolute beginner here. Recently moved to Eagle Pass, TX right on the border in south Texas. Noticed some sandstone slabs dug up at a construction site next door. Started poking around the area looking for fossils. Looked at some geo surveys and found this: "Cretaceous coal-bearing units in the Sabinas folded belt include the Upper Cretaceous Olmos and San Miguel Formations. Rocks in the western part of the map area are Jurassic and Cretaceous marine limestone, sandstone, siltstone, shale, and marl, and minor gypsum and anhydrite." Some photos attached. Any information or hints appreciated. Meanwhile, I'll educate myself as much as possible from info on this forum. Thanks so much, Craig Hyatt Eagle Pass, TX USA
  20. I was gifted a crocodile skull that looks to be sandstone. I got is home and my wonderful dog knocked it off the shelf and the nose broke off. I'm looking for some ideas on fixing it . Any help would be great.
  21. Well, without going into a lengthy explanation, yes, I found this in the Arkansas River about 3 feet under the bottom rocks and what we call the NTS (Nasty Toxic ..., unfortunately my rock hound playground is also a delisted superfund site). It took months to finally get it to where it's at now. About half a year in fact of fervent brushing and gentle filing with a diamond coated pen file. Acid has also played a major role but I'm at the point now where I can't risk using more lest I melt what I'm trying to reveal. Is there any readily available household remedy I can use as a protectant of sorts that I could apply on the delicate fossil material so that I can submerge this thing back into acid? Also, would Thyiglycolic acid benefit me here in this scenario? Thanks ~Noah Benzing https://www.youtube.com/watch?v=tn1uSydlkzQ Here is a view of the underside.... I'm getting close to revealing the actual teeth (although I have unfortunately destroyed one or two so far).
  22. I found these hunting for arrowheads in northern Upshur County. They were on the surface downhill from a knoll after recent rainfall. It's a sandy "red dirt" area, with what I think are some scattered hematite and sandstone or siltstone rocks and pieces. Are they fossils? I'm new to fossil and rock hunting. This is my first post
  23. Hello! My daughter bought me a fossil for Christmas, however, she did not find out what it is or where it came from. Any leads will help. The jaw is 5". It is in sandstone. It was bought in San Antonio.
  24. Hi everyone! I'm new here, but I plan on being an active poster. Geology and paleontology are my passions. I was out at Calvert Cliffs yesterday and the erosion is in full-swing, yielding many a Chesapecten. I also came across plenty of iron sandstone concretions. Everything I have read on the web is about the Navajo concretions in Colorado which are spherical. Obviously these are not spherical and their abundance at the cliffs in all manner of shapes and sizes is intriguing. I was wondering if any of you know how these formed? My geology professor was stumped (he has a doctorate in invertebrate paleontology, not geology, so I can understand). Here are a couple in situ inasmuch as this is where they landed after eroding out of the cliff face. I realize I am guilty of a major faux pas by not including something to scale these formations. One of the photos you can see my shoe so it gives some inkling as to their size. However, I figure you have plenty of experience among you all to know exactly what it is I'm talking about so hopefully this isn't an issue. https://www.flickr.com/photos/alliecat1881/15642517576/in/photostream/ https://www.flickr.com/photos/alliecat1881/15046115813/in/photostream/ I am really looking forward to some insight!
