  1. Ordovician mystery piece. Help, please

    Found this piece in Iowa yesterday while hunting trilobites. I've never seen anything like it. The six point symmetry with it's bulbous tips are very strange. And the fact that it is very water-worn doesn't help with an ID. I'm thinking holdfast or possibe starfish. What do you guys see? Scale in mm/cm
  2. A recent trip to Coralville, Iowa provided me with these coral specimens, each unique in their own way: 1. I posted this a few weeks ago prior to removing most of the matrix from it This rugosa coral was huge!! Check out the scale. 2. The next coral might be mistaken for a mushroom: Oops, I meant this one:
  3. Iowa and Nebraska

    Not sure where to post this, but here goes: I will be travelling west on I-80 through Iowa and Nebraska and wondered if anyone could recommend any easy-access fossil hunting sites within a half-hour / 45 min, or so, off of I-80 in Iowa or Nebraska. Preferably roadcuts or other relatively easy-access sites that are public and known not to draw problems from law enforcement or locals. I'm not interested in collecting vertebrates - just invertebrates. I've never hunted either state. Also, if anyone knows whether there are any regulations against fossil hunting along roadcuts, etc., in either state. Thanks for any help / suggestions!
  4. Reptile head?

    Found in landscaping rocks around my home. my son (10 years old) is very interested in it, so I'm trying to help him identify what it is.
  5. Toe or Finger?

    Found in my rock bed by our porch. Caught my eye as a finger. Any ideas?
  6. My daughter found this in a dry creek bed in NE Iowa. Does anyone have an idea of what it could be? It's about 2.5 inches wide. Any input would be greatly appreciated! Another picture...
  7. Coral? found in Keokuk IA area

    Last fall I was out near Keokuk Iowa collecting geodes during Geodefest 2016. On a day hunt I was collecting really close to Keokuk, Iowa and Hamilton, IL and we were at a site in the Fox River. While collecting geodes I usually will find pieces of fossil corals and throw them in the bucket. I recently had a geode cracking party with a buddy last weekend finally cracking the geodes I collected and found this in a bucket from the trip. I know it was collected in the Fox River and I think the river is actually right over the Missouri border. Looks like a coral to me but wanted to see if I can get a confirmation on that or any more info. Thanks!
  8. ID for Iowa Pennsylvanian Flora Finds

    I joined my fossil club on a spring hunt in a quarry in central Iowa. The vast majority of the exposed bedrock is Devonian, and the goal for most is finding the elusive trilobites. Success was limited on this visit. I had only a dozen partials in my bucket. So after 5 hours of splitting rock, I asked the knowledgeable members about the Pennsylvanian strata that I had read about. They pointed me in the general direction ...up, up, up. they also informed me the exposures were limited to small areas deposited in a valley situation. The glaciers otherwise had removed this strata over most of the area. Sounds like I was going on a wild goose chase! To be honest, finding fossil plants was quite easy. Because of the location, I was very limited to what I could drag down. I am finding it difficult to find proper literature on this group of plant fossils, so I am hoping some help can be had!! Here are a few typical examples. They are about an inch wide: This seems to be something leaf like:
  9. Lepidodendron or coral?

    While I was looking at a recent post here on the forum trying to help someone identify a Lepidodendron tree root I realized I had found something similar to Lepidodendron bark that I had just assumed was a piece of coral since I found it near other aquatic fossils. I found is somewhere near Decorah, Iowa (I don't remember exactly where). It's a bit worn, but does anyone know what it is?
  10. A friend found this interesting rock in Johnson County, Iowa. Does anybody have an opinion on how it came to be?

  12. Ectenaspis Sp.

    From the album Fayette County Iowa

    This is a find from earlier this summer that I just got out tonight to start work on. I assumed when I collected it that it was an Isotelus Gigas and didn't give it much of an inspection. I did tonight though. Appears to actually be an Ectenaspis Sp. A Good surprise.
  13. Bumastoides ??

    I found this in a newly created quarry about the middle of the Elgin member, Maquoketa formation, upper Ordovician of Fayette County Iowa last week. I'm thinking (judging from the little indentations on what I think is a cephalon) that this is some sort of Bumastoides?? I have never found one and it seems a fair bit larger (45mm x 35mm) than what the research that I have of this area indicates. Any thoughts would be greatly appreciated! Thanks.

  17. Did I find a tooth?

    Hello all - I am new to this forum, and I hope that I provide you with the correct information - Please let me know if you need more. I found this today on a sand bar in Iowa; it caught my attention because it looks like a fossilized tooth. The rock part that represents the 'tooth' is different in color and texture than the part that represents the 'gum' area. Maybe it is just an odd looking rock, but I thought I would send it out to all of you experts to get your thoughts. Thank you to all! (this is such a neat site - I am glad that I found it; you are all SO knowledgeable)
  18. What is this fossil?

    Found this fossil at Rockford, Iowa, last week with a student group, and it didn't show up on our identification sheets. It's about the size of a quarter. Can anyone tell us what it is? Thank you.
  19. Confused by Orthocone Cephalopods

    In the driftless areas of Minnesota, Iowa, and Wisconsin I find many Orthocone Cephalopods. Each one seems to have its unique way of being preserved, some as an outer shell, others with their internal anatomy showing. A few weeks ago Raggedy Man posted a cephalopod that looked to be a siphuncle to me. Bev on the otherhand thought it was a phragmocone. No experts chimed in so a conclusion was not determined. That following weekend, I did a little collecting in Iowa. The trip was highlighted with the finding of many cephalopods. As I cleaned the findings, my mind went back to Raggedy Man's post. The more I looked at these collections, the more I wanted to understand the anatomy exposed. I think my biggest frustrations are telling siphuncles from phragmocones. Are siphuncles always smooth surfaced? Should septa be seen in any unworn phragmacone? How does one differentiate phragmacone from the external surface of a cephalopod? Finally does anyone have a good site that ID's our local Ordovician cephalopods? Thanks for any input!!!!! Now enjoy my finds. By the way, since it IS football season, I HAD to use a BUCKEYE to size my cephalopods. If anyone is unfamiliar with a buckeye, it is a little bigger than an acorn. For any of you buckeyes, OH......
  20. Central Iowa Devonian Gorge ID please

    I picked up these fossils near my home in central Iowa twenty years ago. I lived near the Saylorville Lake spillway that broke during a major flood in 1995(?) and exposed some Devonian fossils. Can someone help me with the ID please? The last three pictures are from the same fossil.
  21. Isotelus Iowensis

    Just got this Isotelus Iowensis done with prep. From the Elgin member of the Maquoketa formation (upper Ordovician) in Fayette County Iowa. He was about 12cm long. Too bad he had some damage that I am not able to repair but still a good overall representation of the species.
  22. Hi everyone! I found these fossils here in Iowa and am wondering if someone could help me out with ID. Also, could someone explain to me how the white stripe-like patterns are formed on the one rock that I am holding in the photo. The flat stone with the two circular indentations follow through to both sides (i took images of both sides). The 2nd and 3rd images show a bunch of dark ridge like structures and I am curious what those are of. The 5th and 6th photos I am wondering what the circular type fossil in the rock is of. Thanks for all your help!
  23. Please Help I.d. This Fossil?

    I found this today at the rock quarry located in Crescent, Iowa. I was busting shale when I noticed something shiny amidst the rubble, and found this. The professor on the trip (I went with my college) said she had never seen anything like it before. The shiny part reminds me of mother of pearl. The professor guessed that it may be a wasp, but she suggests that I get it identified by someone with more knowledge/experience than her. Any ideas??
