Working on a Hyracodon Skull, still have some work to do, but here is the progress so far. What do you guys think?
-
Got this jaw/skull piece at a shop recently that was labeled Hyracodon. I don't think it looks like Hyracodon, but I don't know what it could be. Any ideas?

Adventures in the White River Badlands of Colorado
Opabinia Blues posted a topic in Fossil Hunting Trips
I just got back from an amazing and very fruitful week of fossil collecting on the White River Formation in northeastern Colorado. The White River Formation is a very easy and fun rock unit to collect vertebrate fossils on. The White River Formation was deposited during the very latest Eocene and the early Oligocene, though the faunal diversity in the areas I was collecting on suggest it was laid down during the Orellan North American Land Mammal Age, which centers on around 33 million years ago during the Rupelian age of the Oligocene Epoch. I am very lucky to have a grand uncle Gary (no biological relationship to me, is a close family friend who we’ve called “uncle” since I was a toddler) who is a cattle rancher up in northeastern Colorado, and he happens to have a pretty good amount of White River exposure on his property, in addition to some of the neighboring ranches of which Gary knows the owners and helped me to secure permission to collect on a few of them. He really is a great guy and is a real life true American cowboy. He has an interest in natural history and was eager to hear all about the fossils and geology of the area, though has never had the formal education or done the research to learn much about what’s out there. This is the second fossil collecting trip I’ve made to the ranch, though the first one where I’ve stayed for more than one night. The place truly is an amazing trove of fossil treasures and I can’t wait to tell you all about my week! In this thread I’ll make one post for each day (so as to not hit the picture limit too soon). Once I have the fossils prepped I’ll give updates here as well. Day 1, Sunday: My first day at the ranch began, ironically, at my own house. I had packed up the Jeep the night before with my field bag, two coolers filled with seven day’s worth of food, a suitcase full of clothes, and other such supplies for my fossil safari. I left my home early in the morning, took I-76 east to Fort Morgan, and then headed north to the ranch, in total about a 2.5 hour drive. The rest of the morning and early afternoon I spent visiting with and going over logistics with Gary and his wife and settling in at the ranch house I would be staying at, a property that used to be the home of another rancher before Gary acquired the property in 2002. They still maintain the house and it has both electricity and running water, so it makes a fantastic guest house and a place to stay when they’re doing work over on that side of their land. In the evening after I had made myself a quick dinner I decided I wanted to head down to a very productive exposure I had collected on last September for the evening. There was a partial oreodont skeleton that I had discovered eroding out of the hill the last time I was up there, and I wanted to see if there were any more bones there that had eroded out and I could collect. I picked up a few more bones from the feet and ankles that had been exposed in the last eight months and decided to take a scenic route back to my vehicle. A photo of the area of exposure I was in Sunday evening. This piece of badland will become very important throughout the rest of the week... On my walk back I walked over a ridge that I had apparently never been over, becase on a flat wash I noticed a pile of bone fragments. I approached the pile assuming that it would be yet another exploded tortoise shell that are so common in the area. As I got closer however, I was delightfully surprised to see the distinctive black color of fossil enamel, and a bit of digging revealed an eroded Subhyracodon jaw section, along with several loose teeth that I presume had come from the same section of jaw. This find, along with an oreodont jaw section I found later on while walking back to the Jeep that night, would be but a foreshadow of the big finds I would make later in the week. Two photos of the Subhyracodon jaw section as it was found in the field. The jaw section and some teeth after I had cleaned them up a little bit at home this afternoon.- 24 replies

I got this broken up jaw recently and finished putting it together (and some cleaning) today. I still have a little matrix to remove, but it's already good looking Its from the White River Formation in Wyoming. I'm not 100% certain on ID but I'd pretty sure it can be called Subhyracodon sp.

Hello I'm a newbie fossil collector (and newly active member) who happens to several interesting fossils for a decent price from our favorite auctions sites 1st is are Knightia. The seller claims that they are not restored or enhanced 2nd set are 4 Spinosaurus teeth. The seller claims that cracks have been repaired, but no restoration or composition has been made (Pictures 2-9 of teeth in pairs) 3rd is a Lycoptera which the seller claims is not restored or enhanced 4th are plates of Elrathia Trilobites from Wheeler Formation 5th are Fossil Ferns from Llewellyn Formation 6th is a Hyracodon jaw fragment I would like to ask if the sellers' description of the items are accurate and/or if they are restored, enhanced or composites. Cheers!

Hello TFF. This was brought to me today with no location info. It looks like Oligocene White River Group. Person who brought it in said it was collected by his grandparents who took trips to S. Dakota, etc. It is pretty "beat up". My first thought was Hyracodon from the White River Group. It's not Oreodont. Teeth are heavily eroded. The matrix is more reddish than anything I have collected in Nebraska, so maybe it's from S. Dakota? Thoughts? @Nimravis, @jpc (darn blurry pics. I even used a copy stand and timer...)

From the album: Jerry's Really Old Stuff
Mandible and articulated vertebrae from the White River Formation Douglas, Wyoming. The hyracodon was an early ancestor of the rhino which lived during the Oligocene era, sometimes called the "running rhino". The animal was about the size of a cow and one of the larger animals of it's time when most animals were very small.-
