  4. Well I finally had the opportunity to head out to Millard Co. with my Geology professor, the esteemed Forest Gahn. He is one of the worlds leading experts in Echinoderms and he specializes in Crinoids. The guy goes diving a lot to study Echinoderms in their natural habitat and he's managed to keep some Crinoids thriving in a tank at BYU in Rexburg, Idaho. Here's some pictures of the trip to some special Geology and Paleontology sights in south western Utah. I had a blast. Students sitting on the edge of Fossil Mountain, one of the richest Ordovician deposits in the world learning about it's geology from Forest Gahn. The major fossiliferous formations are the Juab and Kanosh Shale formations. In a remnant of the last ice age lake, Lake Bonneville forest scopes up a handful of algae and cyanobacteria rich mud along with Playa (dried up lake). This is an extinct marine animal known as a Graptolite discovered at a nearby Ordovician road cut in Millard Co. UT. No trip is complete without trilobites. Here's a large Asaphiscus wheeleri molt from U-Dig near Delta, UT. This Native American arrowhead was recovered in Millard CO Utah during one of our hikes. My professor claims its origins may be from the Shoshone Tribe. Forest teaches students about the Cambrian marine fauna at U-Dig near Delta, UT. Forest shows students the fossilized remains of a Stromatolite (just above his knee) colony alongside the Lake Bonneville Playa (dried lake) near Notch Peak UT. Here is the view of Fossil Mountain in Millard CO, UT at sunrise. At dusk on the first night we camped at the dunes of Little Sahara which are composed of ancient sand deposits from the Sevier River dumping into Lake Bonneville. Perhaps one of my favorite parts of the trip was being let into the collections archive room at the BYU museum of paleontology in Provo, UT. A lot of the dinosaurs in the collections here are from the Saints and Sinners Quarry in Colorado. Lots of neat therapods including a near complete Allosaurus.
  5. Was hiking across the Colorado River from Dead Horse Point/Canyonlands a few years back and found this. Looks porous and cemented in a siliceous rock. Any ideas? Thanks!
  6. A very rare new discovery: The North Carolina Museum of Natural Sciences reported today that a clutch of oviraptorosaur eggs was found in the San Rafael Swell of Utah. It was a first for the North American continent since these ars typically found in Asia.

  7. Here's a mystery fossil from the Lower Ordovician Fillmore Formation of Utah. My initial impression is it must be a graptolite, but I've never seen any graptolites from this formation with this structure and I can't find any graptolites in my research that look like this. The other thing that's throwing me off is the "rod" running down the middle is preserved actually fairly 3d where every graptolite I've seen is preserved as just a flat film. For reference the specimen is about 2" tall including the middle section still covered in matrix. Any ideas?

  11. Visited the Natural History Museum in Salt Lake this past week. They have a good display of Dinosaurs and Fossils. The first thing you see when you enter is the Lab. There are workers prepping fossils and they have some displays to see. They also have a monitor to show what they are seeing under the microscopes.
  12. Bone ?

    I thought about this as an example of bone from the Morrison formation, but realized that I'm not positive that it is bone. It was found southwest of the ghost town of Cisco, UT. Our target site that day was the old Cactus Rat uranium mine. It seemed harmless since the area was already quite disturbed. By the way I do store it in lead flashing.
  13. Utahs top Paleontologist Jim Kirkland posted this chart on the dinosaur fauna in his state. Pretty amazing diversity
  14. Museum of Ancient Life

    I am currently spending some time in Salt Lake doing some snow skiing. Not much snow sad to say. I made a trip The Museum of Ancient Life in Lehi Utah and thought I would share some of the specimens that they have on display. It's a nice play with about 60 Dinosaurs on display. They also have a lot of small fossils from the Utah and surrounding states. The nice thing is that a lot are hands on displays and are up close and personal. You really get a good representation of their size. First thing one sees upon entering. You are encouraged to touch. Shot of the guys working on a current project. Outside the lab is a jacketed specimen. And yes you can touch.

    Well, i thought I'd show my primitive prepping skills. This is all rather unnecessary as Tony @ynothas already done this thread here and probably better and the pieces shown were kindly donated to me as well. So treat this as a repeat of what Tony does better. Hey ho. So these are the three pieces that Kind Tony sent me. 1. Notice this Elrathia kingii (1.2 cm long) has a break on the anterior margin (cause of death?) .and an upside down Itagnostus interstrictus (5.5 mm) above it and a piece of another to the right of it. 2. This Elrathia (1.8 cm long) has another ones cephalon stuck to its cephalon and some serious damage on the right side pleura. 3. This one is upside down in the matrix. (2.3 cm long) All my prepping was done balancing the specimens on my knee and using a jeweller's loupe to see and a board pin to do the actual prepping. Some water and saliva were also involved, but that was all. First I carefully cleaned as much of the matrix off the first two specimens as i could using the pin and then dug around the third piece so I could 'pop' it out of the matrix. Then I dug all around the other two specimens with the pin and popped them out of the matrix. Here is the third one popped out and with a bit of prep already completed. Sorry for the dreadful photo, but wifey and her camera phone weren't about so i started prepping and then took this photo with my computer as i was impatient to continue. When it was first popped only a tiny bit of the glabella was showing clear of matrix. Here i have popped the Itagnostus before popping the Elrathia.
  16. Link to fossil sites in Utah

    Here is a link that may be helpful to those looking to explore and find fossil sites in Utah. https://ugspub.nr.utah.gov/publications/misc_pubs/MP-95-4.pdf
  17. I am in the Salt lake area for a few weeks doing some skiing and working the boat show. I have got out and hunted a few areas that were listed in a publication but found them mostly picked over. I did find an Ammonite, a small shell and some star shaped Crinoids. Are there any places that you members would suggest hunt around the area? When I leave I plan on stopping in Price to tour the museum there and some of the local area there. Are there any areas that can be suggested to look at in that area as well as along I-70 heading east towards Colorado?
  18. Please help ID Possible Altiocculus

    I found this little guy at U-Dig in Utah, and put him in my “junk pile”. When I took a close look, it appears to be more narrow than your usual Elrathia, with more body segments. Could this be an Altiocculus?
  19. Vernal Utah Visit

    I will be in Vernal Utah in July and I have a free day. Are there any fossil sites open to the public? Or specific museums/sights to see? I know Dinosaur national monument is very close. Any replies or suggestions are greatly appreciated!
  20. Utah Fossil Hunt

    When fossil hunting near Moab, UT this weekend. There was quite a bit of snow in the Moab area this weekend, so I was not expecting to find anything. Luckily, this area was in the Sun and all the the snow was melted off. Found many Brachiopods, crinoid stems, and a small partial trilobite. (I have not been able to take a good photograph of the Trilobite because it is so small, abt 3/8") Attached are photos of the best Brachiopod. It is approx 2" across. I found a slightly large one, but it is still covered in a lot of matrix and needs to be prepped. Fossils are from the Permian Rico Formation about 17 miles down the Potash Road (Hwy 279) South of Moab, UT. Does anyone know of a good reference for fossils in this formation.

  22. U-dig Trilos

    I got a nice delivery of shale from udig for Christmas, i've just been in the freezing cold splitting and having fun. Here are my finds. I'll post better and more clear pictures when they dry. I washed them and put them infront of the radiator to dry, is that a good thing?
  23. Utah's Oldest Dinosaur Fossil

    Found this in the Forums Facebook pages its a paper that describes a sacrum from the Chinle formation of Utah. The Dinosaur Triassic record in Utah is pretty slim and this discovery helps increase their knowledge base. We've recently had posts on Triassic teeth and although this paper does not help us in that area it provides more information on late Triassic dinosaurs of the American west. https://www.utahgeology.org/openjournal/index.php/GIW/article/view/22

  25. Ethrathia Trilobite.JPG

    From the album MY FOSSIL Collection - Dpaul7

    Elrathia Trilobite fossil Utah, USA Middle Cambrian 501,000,000-530,000,000 million years Elrathia is a genus of ptychopariid trilobite species that lived during the Middle Cambrian of Utah, and possibly British Columbia. E. kingii is one of the most common trilobite fossils in the USA locally found in extremely high concentrations within the Wheeler Formation in the U.S. state of Utah. E. kingii has been considered the most recognizable trilobite. Commercial quarries extract E. kingii in prolific numbers, with just one commercial collector estimating 1.5 million specimens extracted in a 20-year career. 1950 specimens of Elrathia are known from the Greater Phyllopod bed, where they comprise 3.7% of the community.
