  1. Some type of trace fossil?

    Can someone tell me if this is some sort of trace fossil? I find them often in the clay in a creek bed that contains fossils of the upper Cretaceous period. Thank you!
  2. Dinosaur Tracks

    Thought I would share some of my Acrocanthosaurus tracks in my collection from Texas. These are from the Glen Rose Formation. Anyone who has dino tracks, please feel free to post them here on this thread too...would love to see them! The associated pair are big...both over 20 inches long.
  3. I went to a construction site near a big lake (Dian lake 滇池) at Kunming, China (Although this city is famous for Cambrian fossil) This place is going to construct some apartments. A lot of workers pass by without realizing they are trace fossil. it's geological map is: from https://www.osgeo.cn/map/m02db the location is around: from IOS's map So it suppose be from Quaternary, right? (but I am not sure if lake trace fossil can produce trace fossil like below) And I found some trace fossil: and some other stuff i am not so sure: and last picture is ripple mark If it is from the lake, that would be a nice vacation place in summer!
  4. This rock was found in the shallow water off the South East shore of Lake Michigan about 20 years ago. No idea what it could be. Any help would be appreciated.
  5. A few Ordovician unknowns

    Here are a few fossils I recently collected from the Maquoketa Group (Upper Ordovician) in northern Illinois that I'm not sure about. 1) Maybe some kind of trace fossil? 2) The two things in question here are to the left and right of the pentagonal crinoid columnal. The small fossil on the left looks like it might be part of a trilobite genal spine? And the three-pointed fossil to the bottom right I have no idea about. I feel like I've seen something similar before but can't remember.
  6. pseudo fossil, starfish

    While walking back to the car I walked over this interesting specimen. I do not know if it is a pseudo fossil most likely, feeding trace of a star fish with lots of arms most unlikely. This comes from the toolebuc formation in central Queensland and is cretaceous. The item in question is 60 mm across. Any comments appreciated. Mike
  7. Here In Washington State! I purchased an estate with a 1925 Argentina Body & Trace fossil collection from a 1924-25 Meteor expedition, the collection has been sealed since 1935 and I am just now archiving the items with photos and as much information as I have. Although I was told all of the items were collected in the same area as the meteor, the specimens span over Millions of years (Billions if going by the estimated 4.5 Billion year old Meteorite) Ammonites at 409-66Ma to Ground Cherries at 52 Ma with the fruit fossilized and a few with showings of the husk at the tops. There are over 400 pieces so I've got a lot of work to do. I look forward to your comments as well as needed help with some of the loose items that are not easily ID (I know there are other species of fruits, nuts pictured below, this is what is next for me to archive)
  8. Deep-water trace fossils

    Hello friends! Today I'm seeking your help to identify a few fossils that I've found over the years. They are trace fossils and I collected them in northern Italy, along a creek. They were not in their original setting, but nearby outcrops dated to the Cretaceous or the beginning of the Caenozoic. These deposits were formed by the action of turbidity currents, in deep waters. If you have any idea for the ID, they are more than welcome! Thank you!
  9. If any one can or would answer a question for me. I am just curious if these trace fossils are of any value?. I will be honest this is something precious to me and my younger brother that found it. It's going to be in our family for many generations to come. This is special and priceless for many reading. The first being we found it on our family property that's been our family for generation. It was located at the very creek our 15 siblings and us have played in and spent all of our Sumner day's in since we was bigg enough to sit in water. This is a special place for our family. My father played their as a child. My grandfather's and his father played there as well. So I can't explain how much that piece of stone, rock what ever else it is means to us. If any one could help i would appreciate greatly. I am not asking for any figure or any thing of that nature. I just want to know if has value aside from the value we god for it.

  11. Just wanted to share the newest addition to my collection. An anchisauripus dinosaur track fossil, collected legally in Massachusetts.
  12. Is this rock considered a fossil

    So is this rock considered a trace fossil or a fossil at all? I am asking because I have seen similar rocks identified as fossils. Thanks.
  13. Help Me Out

    After a little research I think this is coprolite. Rock on one side and something that resembles poop on the other side. See next post for reverse side. Size is 1 1/4 inch by 3/4 inch by 1/4 inch
  14. Strange Steinkern

    This is a steinkern of a fossil clam that I had purchased, the shell itself fell apart almost immediately and this was left. I just want to confirm that the things on the surface of it are some kinds of trace burrows from worms, I am not really sure but that is what they look like to me. Thank you all.
  15. Track traces?

    Found this slab at Jalama Beach, California on Saturday. It was quite different from all other blank pieces we found. Monterey Shale Formation, Miocene. Some of these prints look like bird tracks to me. Any insights?
  16. Kilkee Ireland

    Looking for help identifying what I believe are trace fossil found on the cliffs in Kilkee Ireland. The area is Upper Carboniferous if I am reading the map correctly. Any help would be appreciated.
  17. Scalarituba

    Nice example of Scalarituba found yesterday as float in NE Ohio. I would like others to confirm my identification. Thank you!
  18. Hi all, I have a pair of dino tracks. The left one is a Grallator sp. from the Connecticut River Valley. The right one is an Anomoepus scambus from Granby, Massachusetts. I've been trying to figure out their formation. I know they come from the Newark Supergroup. I would like to narrow it down. Do they come from the Portland Formation?

  20. Trace fossil? Bivalve borings?

    Okay, I had originally just thought this specimen was a 'mother nature playing games' kind of rock when I was out exploring on a day that turned out to be filled with lots of trace fossils. After some online research for Ordovician trace fossils I came across some Flickr photos for Petroxestes pera, bivalve borings, that were once called 'turkey tracks'. The particular photo panel labeled, Petroxestes pera bivalve borings on limestone hardground (Turkey Track Layer, Waynesville Formation, Upper Ordovician; Flat Fork Arm of Caesar Creek Lake, Warren County, Ohio, USA) , looks quite similar to the strange marks I found in this upper Ordovician formation here in southern NM. Any trace fossil turkey track experts willing to comment? Thank you in advance, Kato
  21. Found in my yard in Corpus Christi, TX.

    Was digging up a part of the yard with lots of chert scrapers we found and thought I saw something. Mud was wet so wasn't sure. After it dried I found these inside. Is this something or am Crazy?

  23. Unknown trace fossil burrow

    Here is a fossil shell I found on a fairly recent trip to big Brook nj, towards the right there is a burrow that looks very straight and in the end of one some kind of dark conical figure is located, not sure what it is, any help would be appreciated. Thank you.
  24. Large cone/bowl shaped trace fossils.

    Cottowood Mbr, Beattie Fm, Council Grove group, Permian. Western Greenwood County, Flint Hills, Kansas. I've found 6 of these in only in this one place. They are most likely the interior molds of the actual trace. They were discovered over a period of several months. They were found as tumbled out, not in situ. I'm inferring what's top and bottom due to some obvious features and basic physics. Some retain what appears to be an original edge around the top. The top diameters range in size from 5" to 10+", with heights from 2" to 6". These were found in an area disturbed by oilfield work where it looks bulldozed out for some purpose. Geologically, the area may have intermittently been shallow or shoreline. I've done an amateur's inventory of fossils in the immediate area and found highest numbers are of very! small bivalves.
