  1. 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
  2. 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.
  3. Utahs top Paleontologist Jim Kirkland posted this chart on the dinosaur fauna in his state. Pretty amazing diversity

    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.
  5. 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?
  6. 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!
  7. 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?
  8. 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.

  10. 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?
  11. 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

  13. 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. Kingdom: Animalia Phylum: Arthropoda Class: †Trilobita Order: †Ptychopariida Family: †Alokistocaridae Genus: †Elrathia
  14. Utah Ammonite Help

    I found what appears to be a small (1 cm) ammonite in Green River, Utah back in 1993. Anyone have any idea what genus it is? I don't know the geologic horizon I found it in but looking at a geologic map of the San Rafael desert, it's probably Cretaceous. I do remember it's from the East bank of the Green River, near the Old Highway Elgin Road. Matrix appears to be limestone if that helps (reacts vigorously to acid). Thanks for the help.
  15. Utah Peronopsis/Agnostid trilobite ID

    I found a few lists of trilobite species from Utah, but am having trouble finding any information on telling the Agnostid species apart. Looking for some sort of papers, book, illustrations, pictures or something that can help me make sense of the differences between, say, Baltagnostus eurypyx, Itagnostus interstricta, Peronopsis interstricta, and etc. Thanks!
  16. Hello Fossikers! I am going to be in Torrey Utah and surrounding area in mid September and would love to go hunting somewhere....any suggestions? I'm not at all familiar with the area so any info would be most appreciated! Thanks!!
  17. U-Dig

    Had an awesome day digging at U-Dig with @FossilSloth So the hound and the sloth hung out today and we pounded rocks from sun up to sun down. I found the largest Asaphiscus wheeleri I've ever seen and Justin scored a good number of Elrathia kingii. The find of the day a was massive Asaphiscus wheeleri. The trunk is full of Utah trilobites to prep this winter. Had an awesome day. Exhausted yet determined to find some more. The U-Dig season closes soon and I already miss this place. Justin and I holding up some of our finds. It's always fun meeting up with another forum member. Justin hauled off seven buckets full of trilobites, sponges, and brachiopods! One of Justin's buckets. I see an Elrathia kingii multiplate! Another Elrathia kingii awaiting preparation. Really going to miss this place. Sunset over the ancient sea ways. Up close of the day maker. Another angle. I'll post more trilobites as I prep them out. Found a myriad of Perenopsis and will post those later. The site manager showed us a secret spot full of them. Here is a video of all the neat trilobites we found in between one of the Shale slabs: That's all for now folks!
  18. Pennsylvanian \ Permian Tooth ?

    Think this is a tooth fragment. Found in the Rico Formation near Potash, UT which is just outside of Moab, UT. 1 1/4" x 1/2".

    Perenopsis multi-plate from U-Dig. @Kane an old timer to the site showed me were to find these and after a few hours I found a couple with 5+. I said I'd get you another one, but perhaps I could up the stakes for another E. rana. Stay tuned!

  23. ALGAE ?

    This was sent to me in a sort of starter pack of fossils from the United States about 40 years ago. It doesn't look like any algae or stromatolites I have seen from this site. Any ideas anyone? More pics to follow.
  24. A Short Trip For Jurassic Limestone

    When our Plan A was killed we had to go to Plan B. Plan A was to visit a couple of old mines and sample the mine dumps for pyrite crystals and to try my hand at gold panning some of the tailings a little. This couldn't happen as there was some sort of bike race going up and down the canyon the mines were at the top of. Not wanting to waste the drive over there, we decided to visit the nearby limestone outcrops and viola! Pentacrinus crinoids! More pics
  25. The apparent demise of the best California, Utah and Nevada area paleontology website is premature. Inyo.coffeecup.com (created by a former TFF member) is up and running. Check out his great write ups with pictures about trips to many sites many now under protection by state and Federal governments. http://inyo.coffeecup.com/site/cf/carfieldtrip.html#fossilspages Download his fieldtrip guide: http://inyo.coffeecup.com/site/fieldtripbook.pdf Here are two of my favorites sites: Red Rock Canyon State Park in the California Mohave desert http://inyo.coffeecup.com/site/redrock/redrockfossils.html and see the magnificent silicified insects from the Miocene lake deposits near Barstow, CA http://inyo.coffeecup.com/site/barstowfossils/barstowfossils.html Thanks to TFF member @John for alerting us that his wonderful website was down. In a related matter, I would hate to see Inyo.coffeecup.com dissapear if the creator is incapacitated or runs out of money to support the site. Besides The Internet Archive AKA The Wayback Machine, I wonder if any institutions would be willing to archive a version for posterity. Books are archived in libraries; where should websites be saved? I wonder if The Fossil Forum would be willing to archeive copies of significant paleontology websites. Have we made plans to carry on and archive The Fossil Forum in case disaster strikes? Maybe geology libraries and paleontology departments at colleges/universities should store and archeive quality paleontological websites. Sometimes quality websites such as Mindat.org (minerals and occasion fossils) find institutions to preserve and support their continued operations. Mindat has Hudson Institute of Mineralogy, a 501(c)(3) not-for-profit organization. Has The Fossil Forum ever considered forming a 501(c)(3) not-for-profit organization to support our activities or finding an institution to partner with? As an added bonus donations to TFF would be tax deductable. Cheers, John
