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!

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 not sure. Any thoughts on what it could be?

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 mostly stayed in hotel. However, it was cooler in the higher altitudes with much lower humidity so… Stopped at Fossil Mountain to camp. Couldn’t do much on the mountain itself where the good stuff is at, but enjoyed a cooler evening and morning. Didn’t get any fossils worth reporting, but was nice spot to relax. From there I stopped at Crystal Peak and scored a few pygs in a wash near the road.

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.

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 eye (taken at 40 or 50x). Each square shown in the scales is 5mm x 5mm. The difference in structural types could be due to weathering down from complex to simple. They could be tracks, feeding tracks or parts of burrows. They could be cruziana, though I have never found anything resembling the "cruziana" I have seen described in numerous illustrations and photos labeled as such. One would think there would be such things in the Wheeler Formation, what with all the trilobites and other fauna there. In the renderings I have seen, cruziana look like TWO of the circular elongates, directly side-by-side, not single strips that I see. First, we have the circular elongates. They look as if something had been feeding in a circular pattern, but all along moving in one direction while doing so. Check out rhizocorallium.

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 working on pulling those pics of my other device. ' Mystery-O-Saurs

Hello all, I was raised in Vernal Utah (dinasaur land) and have been collecting fossils my entire life. My siblings and I would find dinosaur bones across the street from our house and thought everyone had dinosaurs in their yard. Lol. I went to BYU Idaho and majored in Geology. I transferred to Casper College and was studying extractive resource technology and mud logging, but didn't finish due to a realization that fossils are my hobby, not a career choice....and I'm terrible at mathematics. Hahaha I love fossils, gems and minerals and am excited to learn from this group and see some neat finds.

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.

Hello, I'm from Evergreen Colorado. I found my first triceratops bones when I was 8 years old near Boulder and i've been looking ever since. Now that I have a young son, i'm getting back into the hunt. I'm having harder time finding fossil sites now days compared to when I was younger, seems like everything is private property these days. I'm looking for new places to check out and exciting journeys to take my son on and ways to educate him on our ancient world. I look forward to getting to know everyone here. Thank you!

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

Any ideas what this could be? I found it by a dried up river bed outside of St.George Utah. There was a lot small pieces of petrified wood close by.

A new super cool ootaxon of eggs and very different that what we are familiar with is presented in this paper : Stillatuberoolithus storrsi from the Kaiparowits Fm of Utah. Eggs are tiny at around 18mm and " the exact identity of the egg producer is unknown, the eggshell microstructure and small size is consistent with a small-bodied avian or non-avian theropod" Paper: https://www.nature.com/articles/s41598-021-89472-1#disqus_thread @-Andy- @HamptonsDoc

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 annual dino-themed half-marathon. I mean, come on, how can I NOT run this race??! So, my shift at the fire dept ended at 7am this morning, and at 7:01 I was on the road in Oklahoma. I have to say, being a fossil hunter sucks as you drive! Driving up the Kansas 281, just shy of I-70 there is a very nice uplift with lots of cuts and looks to be a lot of shale. I wanted to stop and inspect some interesting road cuts, but I had zero time to waste. So I drove past fossil lake, onto I -70 towards Colorado. I waved hello as I passed by the Sternberg in Hays, and I spotted a sign for another museum (the Fick or Frick, I cant remember) so I will have to go back and visit when I have more time. Of course lots nice chalky outcrops visible driving through that part of Kansas, an so many wonderful fossils buried. The bad part about driving through this part of the country is that every mile looks pretty much the same. Hour after hour of the same flat plains and wind turbines. I made my only stop for fuel in Limon. 500 miles and only about halfway there. I finally caught sight of the Rockies about 100 miles east of Denver. I always love mountains, and catching the first glimpse on a trip is always special for me. Dont know why, just always love it. But then I had to drive through Denver. I hate Denver. North/south or east/west it doesnt matter. Driving there is always horrible. Then You have I-70 through the mountains. Lovely. Beautiful. Majestic. Hair raising. You have 200 miles of road that twists and turns, sometimes very sharply, packed with drivers. Some want to drive 80, some want to drive 50, and then the semi trucks which can barely drive 30. Then mix in construction every 10 miles. I'm just glad I wasnt pulling my camper this trip! On a side note, dont go to Vail. I pulled off into that town to try to stop for a pee break. WRONG! Never driving through there again. The interesting thing about this road, is that most of the middle is the volcanic/granite/iron/gold/etc mountains. Then as you drive, you come around a bend and suddenly you are surrounded by massive sedimentary cliffs. Without consulting a geological map, I think it was probably Morrison formation, at least part of it. Then things flatten out and get boring until I reached Rifle. As soon as I got north of Rifle on hwy 13, its just dino hunting drool inspiring formations. All the way up to Dinosaur Colorado and of course continuing on to Vernal. Just mile after mile of hills, cuts, valleys, washes, and mountains of sedimentary layer I want to climb and explore. Finally though, after just short of 14 hours of non-stop driving I arrived. Dog tired but too wired to sleep at the moment. Race isnt for a couple days, so tomorrow will be prospecting for sea-life and seeing some local sights. After Saturday's race, I'll go hunt some more before heading back home for another 14 hours marathon drive. I'll post pics and report on some hopefully productive digging!

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. Any help is appreciated. Thanks! IMG_5098.HEIC IMG_5100.HEIC IMG_5102.HEIC IMG_5104.HEIC IMG_5108.HEIC IMG_5109 2.HEIC IMG_5111.HEIC Whoops! I just realized I attached the first trilobite's images as files instead. I'll try to upload them as images instead in a reply.

Interesting article with extraordinary claim. https://www.washingtonpost.com/climate-environment/2021/04/19/grand-staircase-tyrannosaur/ Link to the paper: https://peerj.com/articles/11013/

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 minus the cheeks (of course) measuring 1.5 cm in length. It isn't the cleanest & I have a bit more to do, but I wanted to "show it off" as it were. And see if I got the I.D right. Not the greatest quality pic, but I've also been up for almost 24 hours, so it may just be my imagination (pic quality or that I actually took a pic).

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.

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.

Hey all, I bought this trilobite from a seller today and was wondering if anyone could help me ID it. I'm pretty sure its from Utah, and I think it's an Elrathia, but I just want to get some other thoughts or opinions. In the bottom left there seems to be part of an agnostid, but I could be wrong. The seller said that they didn't know where it came from unfortunately.

Today is my 50th birthday so I wanted to select my fifty favorite fossil finds to present. But....because I am obsessive, I couldn't settle on just 50. So here's 150. My favorite 150 fossil finds. And there's still more - but then it would be 250 or 555...I don't know. Anyways, enjoy. Mostly Texas, some from Utah, Florida, North Carolina, New York and England (denoted by the state initials or UK). Almost all were found by me, except about 4 which were gifted to me. I did actually narrow it down to 50...initially. But then I had to do pages for the rest of them because I didn't want them to feel left out....
