  1. Hi everyone, I've been hesitant to post this fossil on here for a while as I didn't know if I wanted to hear a response which would contradict what I had hoped this would be. However, I recognize that to maintain a reliable and accurate collection I would have to properly identify what I found. The fossil in question is a possible partial egg that I found last year in the White River formation of Wyoming (Late Eocene/Early Oligocene) w/PaleoProspectors. This formation is known to produce fossil bird and reptile eggs (in fact, someone found a large, complete egg on this ranch the week before I was out there) so I knew that there was a possibility. When I found it most of the inside still contained sediment, which I have since gently scraped away to the best of my abilities. It has an odd dent in the top and no obvious pores, but the overall shape and the apparent shell make me think this is an egg. It is 8 mm tall and about 10 mm in diameter. I want to know what you all think. I would especially like to hear the opinions of @CBchiefski @jpc @MarcoSr @Auspex@Troodon Interior of the egg before I cleaned out the matrix. After I scraped away the matrix. Here's two views of the top.
  2. Today I went with Dr. Steve Nicklas and others from PaleoProspectors to a private ranch outside of Lusk, WY to help them excavate some Titanothere fossils from a bone bed they had discovered earlier this season ahead of the guests arriving for this week of fossil hunting. It was a hot and humid day (for Wyoming) and being in the white river formation where the white exposures reflect the light back towards you, it only made things hotter. But we dealt with the temperatures and got some awesome fossils out of the ground. I also got to keeps some fossils I found that weren't associated with the working area. Here are some pics-
  3. White River fm. Mammal Teeth

    Hey everyone, I found these teeth in the White River fm of eastern Wyoming last summer and wanted to see what people on the forum thought they were. 1st is what I believe to be an oreodont tooth (possibly Merycoidodon). It's .8 cm wide and 1.5 cm from root to crown. 2nd I believe may be a Poebrotherium tooth but I'm unsure. It's about .5 cm wide and .9 cm long. 3rd may be from a Leptomeryx but I'm not sure. It's about .4 cm wide and .9 cm long.
  4. Wanted to Confirm this ID

    Hi all! I found this jaw section in Wyoming's White River fm. last year and was told it was likely from a dog (hesperocyon potentially). I wanted to confirm it with some of the people on the forum as there's not a lot left on it aside from part of a tooth, hopefully someone can affirm my hope that this piece actually belongs to a canid.
  5. Oligocene Nibbler?

    I want to confirm that this bone fragment has the evidence of gnawing from a rodent or other mammal on it and if it's a common occurrence or not. Found this summer in the White River fm of eastern Wyoming. Here's both sides of the fossil-
