  1. I try to identify any fossils on my own before I post it on here, that's how I learn! Anyway, I found these three shark teeth while pre-washing the matrices from Kiowa Formation (Location: Ellsworth county, Kansas. Age: Albian). A couple of them came loose during pre-washing and I found another one still in the matrix. Tooth #1: Is this tooth from Meristodonoides sp.? The views are from front and back of this tooth. Approximately 2mm long. Tooth #2: Is this also from Meristodonoides sp.? Approximately 3mm long. Tooth #3: Is this from Leptostyrax sp.? Front and back views of this tooth. Approximately 6mm long.
  2. Fish tooth #2?

    I named this topic as Fish tooth #2? because this fossil is very similar to my another fossil in a previous topic a while ago. Nobody really have any consensus on what it is and I thought it might be a fish tooth. I hope I will be lucky this time to have someone identify it for me with confidence. Located in Ellsworth county, Kansas, age of Albian, and from Kiowa Formation. It's approximately 4mm long. I know identifying specimens from Kiowa Formation can be a real pain since it's so little researched! lol...
  3. ID this ?dino?

    ·Big Brook, NJ, USA ·Panned fr brook bottom w marl+ ·Miocene form. overlaps Late Cretaceous? .Attach: images of 2 fossils .(found pre-2020) I assume these (3+1) fossils may be from the "same" species, two diff. animals? No outstanding horizontal/diagonal "veins" from the prominent central ridges. Rookie request to ID b4 summer trip to c Dr. Parris, NJ St. Museum, Trenton. Thx
  4. I found these that resembles burrow or root cast in Ellsworth county, Kansas, USA from my previous trip. The formation these came from are most likely Kiowa formation/Kiowa Shale and the age is Albian. Here's the link to my previous trip. I'm just catching up with the prepping and sorting my fossils from my previous trips. I am wondering if it is some sort of ichnofossils. Is it burrow, root cast, or something else? Also, is it possible for it to be from geological origin rather than a true ichnofossil? This one is the largest I found. The center is poorly cemented sandstone and can be easily brushed off with a toothbrush while the outside layer is hard. Notice the winkles around the interior bend. The measurement is in inches (I know I need to get a metric system badly, my apologies!)
  5. A spiny Brachiopod

    I found this spiny brachiopod in my boxes but thre are no more label in the bag,i think it's probably from the States the other side is not very nice but a spiny brachiopod is not very common,someone could help ?Thanks!

  7. The past two weeks I have made three trips to hunt for fossils, particularly from Kiowa formation/Kiowa shale here in Kansas. The first trip were local: the outcrop in my hometown, Salina. The next two trips were in Ellsworth county, Kansas; which, is only about 30 miles/48 km away from Salina. My first trip to the local outcrop were not productive: I knew it is relatively non-fossiliferous and never found any fossils there despite of growing up in this town and visiting this area all of my life. It wasn't until two weeks ago (March 25th, 2020) that I have found my first fossil from there and I'm pretty certain it's planolites burrows. The second and third trips in Ellsworth county were quite productive! I have found mostly plant and shellfish fossils but also found few trace, vertebrae and tooth fossils. The area where I found these would be underwater when the reservoir level is high. I have so much to do the basic prep for the next several weeks... My first trip to the local outcrop in Salina, Kansas, and found a fossil containing planolites-like burrows.

  10. Interesting fossil

    I found this very interesting fossil yesterday and I do not know what it is. Found it in Ellsworth County by Kanopolis reservoir. It's from Kiowa formation/Kiowa Shale and age is Albian. Dimension is 5/16 inches wide and 3/8 inches long or about 8 mm wide and 9.5mm long. I have never seen anything like this before and I hope somebody else have an idea what it came from!
  11. Fish tooth?

    I found this matrix containing something that reminds me of the fossilized fish tooth pictures that I have seen around on here. When I noticed this, I chipped this matrix section off of a larger shell hash plate containing mostly Turritella sp. and bivalves. Its original location is in Ellsworth county, Kansas at Kanopolis reservoir. Age of this matrix is Albian and it is from Kiowa formation-Longford Member. Length of this 'tooth' is about .25 inches/6.5 mm. Can anyone identify what it is? It is currently soaking in a bowl of water, I hope to remove more of the matrix off to get a better look at it. Do you have any advice/tips on how to do it without breaking the 'tooth'? As you can see it, it's very small and I have nearly no experience in prepping the fossils beyond the washing and brushing with toothbrush.

  15. I live in the Northeast of the USA. I found this bone out in the forest yesterday and I’m having trouble identifying it due to its size. As shown in the photos, the bone looks very scratched up, probably chewed on, and both joints on each end have been snapped off. The bone was cracked down the middle, then fell off my counter which split it in half. I don’t have a metric ruler, but 12 inches is about 30 centimeters. If it had the joints I think it would be closer to 15 inches, or 38 centimeters. I was thinking it was a white tail deer tibia or possibly a femur (I was leaning more towards tibia due to the curvature) but everything I saw said that deer tibias and femurs aren’t more than 10-11 inches even with the joints. I know it’s pretty broken up, but guesses from anyone?? Thanks! (Can’t upload all the photos due to file size so I will comment with more)
  16. Hello! I am an MPhil student studying plesiosaurs, I am really struggling to locate Cretaceous aged specimens. Since I am based in the UK, most of the museum collections contain Jurassic age fossils so you can image I have an abundance of these! I thought it would be best to ask on the fossil forum since people from all over the world use this. Does anyone know of any museums in Europe or the US that contain large marine reptile collections that might contain a lot of plesiosaurs?
  17. Antiquatonia maybe? (Brachiopod)

    I think this is the genus Antiquatonia, but I’m looking for some confirmation. I found this back in April, going through my finds and trying to ID. Found in Limestone. Glenshaw Formation (Conemaugh Group)

  22. Carboniferous Limestone

    This piece of limestone looked like sea shells (clams or brachiopods) at first glance. However it’s one bumpy continuous surface. Any idea? The rock would be around 305 million years old. The rock broke easily along this surface which made it easy to see. Shells typically show white preserved Agagonite on them as well. No such preservation on this surface. Rock from Western Pennsylvania, United States. The surface is wet. Ruler is in inches.
