  1. So, I had planned a long trip for this year and built a vehicle for it. However due to some health issues I had to cancel. However I still had the time off from work and the weather here in Omaha was not good for recovery. so I got some help packing up the new to me fossil hunting Jeep and headed west to San Diego. Plenty of time to burn and a vehicle with AC helped, so I took a long and inefficient route to SD where the VA has a better cardiovascular clinic. As I could only drive for a few hours a day and due to heat and wildfire smoke, I took stopped frequently and
  2. I had a bit of spare time today so I thought I'd prep a trilobite or two from my trip around the Confusion and House Ranges of Utah. (See trip report here) I had found this guy in someone else's throwaway pile probably after it came out chipped and subsequently scraped. I didn't think it was worth leaving out in the elements so I brought it home. Here's a before picture. After 4 hours of swapping between dental picks, wire brushes, toothpicks, and various Dremel attachments here is my final product. It's not perfect at all bu

    Stumped: Gastropods from Dugway Utah

    So, there’s a very bright, yellow-white exposure of a very soft sediment in the Dugway Geode Beds near Site B. I cannot find anything about any fossils from the beds proper. Im guessing these are in the Lake Bonneville Pleistocene era. Have been unable to find any details on these guys and sadly have no clear data on the various members exposed in the area due to the famed geodes. All suggestions welcome!
  5. I would like to show you all some items I have termed "elongates", so as not to hint as to what they may be. They could be a number of things, but they all form elongated strips. I have grouped them into several different types, based on structure. Interestingly, some of these combine different structures or all of the above, so these may all be the same kind of thing. Some of them extend short, and some of them are very long, taking all kinds of twists and turns. They all show the same structural features whether they are almost microscopic (taken at 250x) or quite visible to the naked e

    Navajo Sandstone trace fossil?

    I saw this potential fossil in the Jurassic age Navajo Sandstone in Zion National Park in Utah. I'm sorry that there is only one picture with no scale. I was hurrying down the precarious Angel's Landing trail with a long line of people behind me, so I only had time for a quick picture. The feature is probably about ~12 inches long, and I believe that it is situated on the plane of a cross-bed in a dune structure (example of the cross-bedded sandstone is also pictured). This feature might just be some sort of iron precipitation, but it looked so similar to an invertebrate trace fossil that I am
  7. I picked this little nugget up quite a few years ago, during my early infatuation with coprolites. All I know about it is that it was found near Price, Utah. I have siderite "formations" from around the world. This is the only one I've seen that looks like it has an inclusion (or should I say the cast of an inclusion). There has long been a debate as to whether siderite rocks such as these are coprolites, casts of voids (fecal and otherwise, or iron-rich mud extrusions (what I like to call "Earth poop"). My questions are: 1. Does anyone happen to recognize what formation this might
  8. Allosaurus

    Utah Vertebrae

    So I sorta impulse purchased these 4 little vertebrae from a rock shop (they were cheap, and looked like nice teaching specimens). They are from Utah, but have no further provenance than that. I am fully aware that complete identification of them is impossible without locality, but it would be great to even just get them down to a family. And heck if someone might have an idea on what formation they could have come from I'm all ears.

    Jasperized Petrified Wood?

    I have a decent collection of petrified wood I've found here in Utah mainly Triassic Chinle, Jurassic Morrison, and Cretaceous Cedar Mountain Formations. This one has me a little stumped though and I am mainly looking to see if anyone has seen something similar to this. I'm about 80% sure it's jasperized petrified wood. Possibly an old rotting log. This was found near Park City, Utah in Keetley volcanic strata. The locality is not from the ash deposits that produced the nice Silver Creek Junction petrified wood (now extinct under commercial developments) but more likely from the violent lahar
  10. Here are images of the 6 honeycomb pattern patches found in my Wheeler Formation collection. First image: 1 mm long Second image: 1mm long Third image: 1.5 mm long One image missing - couldn't get to focus. Fourth and Fifth images: 2.5 mm long. These are facing images of each other - original fossilized and impression - same specimen. I tried my very best, but images are still a little fuzzy, despite higher magnification.

    Utah - Dinos (Raptor + ?)

    Hello All! Found a pocket of dino in the Moab area of Utah. I'm confident one is a raptor, but I may be wrong. The other I am not sure about. For reference, they were right around the corner from each other in the same pocket. Just a note - these are WAY off the beaten path in an area very few people would be able to get to. Quite frankly I was surprised to find them in this material as opposed to conglomerate like most of my other finds. Thanks in advance for your help! Raptor (?) - The whole thing was there down to the tail, but I am still wor
  13. I keep finding partially fossilized or mineralized bones in our yard. We're about two miles from the mouth of Weber canyon Davis County Utah. Found some mineralized snail shells in the same area as the bones. We know that before highway 84 was built, our house would have been on the edge of the river. Any help identifying would be greatly appreciated.
  14. Hello, I'm taking my son (9 years) on a 6 day road trip from Evergreen, Colorado to anywhere in Utah. We're avid fossil hunters and spend a lot of time looking in Colorado. We're going to do a trip to Utah and i'm building out the itinerary now. At this point, we're entirely flexible. That said, since it's just a few days, I was thinking about focusing on the Moab area and then heading back home through Telluride. Would love your ideas for places we should go or stop along the way. Thank you in advance, we really appreciate it!! Dan

    Vernal road trip

    This is probably going to be a long post, so I hope you're bored! This is an area I have wanted to visit since I was a little kid and first wanted to be a Paleontologist. Unfortunately, this area was a long way from my family's normal vacationing route so I never made it. One of my other past-times is running. I got into running half marathons and then decided I wanted to run one in every state. I was supposed to come last year, but, well, covid sucked the fun out of everything. Anyway, Vernal Utah (known as dinosaurland and home to the Dinosaur National Monument) hosts an annu

    Trilobite ID Help

    Hi everyone, I have some trilobites I need help with identification on. I acquired these several years ago, so I am not entirely sure where these trilobites were found and can only suspect. The first is a trilobite that I believe is from Morocco. It is around 6 cm in length and 3 cm in width. The other two are Agnostid trilobites that I believe are from Utah. I was wondering if it was possible to limit each down to a genus. The darker one is 6 mm in length with a thorax around 3 mm wide. The lighter one is 7 mm in length with a thorax around 3.5 mm wide.

    Elrathia kingii?

    I recently purchased a 40lb box of shale from U-Dig Fossils in Utah. Mid-Cambrian, Wheeler Shale Formation, House Range, Millard County, Utah. This morning after work, I split a smallish piece & one side had an odd dent, the other had an indistinct, slightly raised shape that sort of looked like a trilobite, so I started trying to find out if it was. This was the result. Using dental picks, a needle in a small pin vice, a # 428 Dremel wire brush (by hand) & another small, round nylon brush (Dremel) in another pic vice... and lots of patience. I think it's most of an Elrathia Kingii min

    Caramel colored petrified "wood".

    I recently found this fossilized example on the surface of the desert in east central Utah, Emery county, on the road to chimney rock. The caramel color isn't typical of the petrified wood that I've found before and I'm wondering if this might be another plant such as a palm, fern, cycad, or something else. Growth rings are present but are not particularly strong. The "sap" inside appears to have turned into a different type of mineral. The light green highlights on the surface are lichens and are not part of the stone. Any ideas as to what type of plant this is? Thanks.
  24. Is this a skull of a baby raptor or is it just a rock? I just want to be sure before i take next step.
