    What is this?

    Found this laying on the surface of a flat sandy area in southern Maine. I'm not sure what it is.
  2. All of these are from the Winterset Limestone Formation and dated to the Pennsylvanian period Found in Missouri I found this in a rock that was completely covered in these structures and had many layers to them Here are a few I decided to take home with me Natural color in daylight (measurements are in the last photo of this specimen): Specimen #2

    Pointy Spiral Shell

    Helotes, Tx Part of this shell was sticking out of a chunk of sediment. I used a water pick to clear the rest of it. In trying to determine what kind of shell it is, I’ve found several that are similar, but none with the shell spiral as tight. The closest thing that I could find is below. This doesn’t seem correct considering my location. Placostylus porphyrostomus is a species of large air-breathing land snail, a pulmonate gastropod mollusk in the family Bothriembryontidae. This species is endemic to New Caledonia.
  4. I have pulled all of the dark sediment. Below it is more of the sediment that I’ve been finding. On the top of it is a white powdery substance. Is this just efflorescence? It’s also on the bottom side of some of the darker sediment.

    Working sediment

    What is the best way to work sediment pieces without completely destroying everything? There are two spots in my backyard that my dog constantly digs at. Both of them are in different ares of my concrete porch, within about six feet of each other. Below is a piece that I removed recently.

    Sediment with Rock on top

    Below is a piece of sediment that I pulled from my yard here in San Antonio, Tx. I’m just not 100% sure on what type of rock this is sitting on top of the sediment.

    Vegetation question

    San Antonio, Tx How long will vegetation in sediment stay alive? I’ve had this piece of sediment that I found here at my house set aside for about two months.

    Sediment coloring

    San Antonio, Tx I was curious as to what would cause a difference in sediment coloring? This piece isn’t like the other hardened sediment pieces I’ve found in my yard. The others are more brown or tan in color.
  9. San Antonio, Tx Do limestone and/or sediment formations tend to repeat a formation in similar shapes and sizes? The one on the top left appears to be a clay bottle.

    Sediment ?

    Is this just fossil mud with worm holes?
  11. My father found this in the mid 70s in Eastern NM off the side of a road after a rain storm. He thinks it washed out from the ground. It is larger than a fist and very dense. The white is paint my dad accidentally got on it. Looks like a rope tied around it and cross crossed; 2 areas look knotted. I wondered if it is a petrified drinking apparatus. Any ideas?

    Newbie looking for ID help

    I am fortunate to have moved to the Bighorn Basin in Northern Wyoming with all of the awesome geologic structures and fossils. I work in healthcare but love learning about all things science. Wyoming is awesome...where else can your son's 8th grade class take a field trip to dig up trilobites (and bring them home) and walk in dinosaur footprints. Anyways, saw this structure in sediment rock in the northern bighorn basin. The rock layer is just below the red chugwater dirt layer (I think). There are multiple coin sized fossilized shells and softball sized coral pieces. This str

    Any ideas of what this is?

    I found this yesterday in a field in Southern Central Minnesota. The field borders a prairie pothole lake. I also found a small shell impression in a sedimentary rock there in the past. In the photos there are 2 like impressions that continue around the piece. Appreciate your thoughts. Thank you.

    Bones maybe

    Ok here are some interresting finds, I suspect they are fossils, suspiciously looking like bones, some occasions there's indication of merrel. Location: edge of Moni formation, 3km from sea, 3-5million years old. Under the very end of a series of limestone slabs, in a layer of mud. All in a 2 square meter radious, attaching also some I could not remove from there. diameters vary from 5mm to 35mm and the longest is 20cm. Near by I found also oyster parts and other bivalves and a couple of plant shaped white material embeded in stone. here we go: 1) all together

    Pleistocene

    Hello all! It's been a while since I've been on the forum but I'm back with a question that has been nagging at me. Where does one search for Pleistocene fossils in Nova Scotia? Most of the fossils in my collection are composed of shale and depict leaves and sticks. Not that there's anything wrong with them, it's just that my the Pleistocene epoch has really caught my interest these last few weeks. My internet research hasn't provided any fruit so I thought I would bring my question to this wonderful community of fossil experts and hunters. I know that mastodon and other Pleistocene fossils ha

    miscellaneous non biogenic tracks

    I love this little gem by a man who knows all about ichnofossils. Wish it were a slightly longer piece. Good documentation of the marine influence (waves,e.g.)on the upper layer of sediment . Enjoyable!! TiltingSed Geol 288.pdf edit: so it's basically about non-biogenic ichnites,but in a lot of marine environments the trackmaker( in the cases documented in this article passively being moved about) will be an organism,of course.

    help with ID please

    hi all, a member of my local fossil club is wondering if the specimen he found in the bottom of a dam in Calgary, Alberta, Canada, might be a fossil, or just a mineral. The specimen is about 3 inches round. Sorry, but the 2 photos i have are only of a standard quality. cheers, kevin
