A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Hi all! I was hoping I could get some assistance identifying some fragments that lie around two small bones that are visible. It seems that whatever the shell like pieces are, that they do wrap around whatever is encased inside the rest of the rock as they also appear on the underside. It looks as if it actually wraps around the fossil, almost like skin since it does contour around. Underneath the fragments are a porous, almost spongy tissue substance between the fragment and the actual bones. Thanks in advanced! I've been searching nonstop online and have not been able to tell what they were.

6" Fossil found at about 9000-10,000 elevation late July 2023. From Summit County, near Alpine Acres. What is it!
Gordon Johnston posted a topic in Fossil ID
A family friend found this recently in the forested mountains near Oakley, Utah, by Alpine Acres. It stumps me. Would appreciate any help identifying it. It was near a bunch of marine shells. I am putting in a couple photos of the 6" fossil, a couple of the seashells he also found there, and a photo of what I think is a concretion. Many thanks, Gordon

Hi friends! I recently took an 8000 miles road trip across the western US and got to visit a lot of rock shops and roadside sellers (the selling out of their yard folks always have the best stuff). I bought these from a guy near Zion, he didn't know what they were. Any ideas?

Next to my laptop at home is a 3X5 card with a list of 6 fossil hunt destinations in random order. With less than a work shift on Happy Friday, I thought about that list and knew there was 4 hours of daylight available if I left work at 3PM. And a close by destination could leave me up to 2 hours of at least scouting said destination. So that was the plan. Leave at 3 and drive east of Salt Lake City to a certain named canyon famous for its red agatized Horn Coral. I did some research and due diligence on the site and discovered the status of the land - US Forestry Land -Unita - Wasatch- Cache National Forest. And that also there is a current mining claim attached to that site - basically the entire top of two hills. Which gives the mineral rights to the Claim Stakeholder. My excursion then became a no dig scenario. So no pick, shovel or rock hammer went up the hill with me. Speaking of hills, it tops out at 8,000 feet above sea level at the summit. That is exactly the point at which AMS ( acute mountain sickness ) kicks my fanny. I've summited several 11K footers here and like clockwork, I pass that 8K foot line and the nausea starts, but I won't go into the details. AMS is cured by going down the mountain. It took me an hour to summit and arrive at the site and the descent was 30 minutes with some trail running in there. It had just rained and despite nylon gaiters, the trail bushes soaked me from mid thigh down. My La Sportiva full ankle hikers have never been so wet - I hike the desert or clear mountain trails. My Marmot pants were quick dry but not the boots. Oh well. I had know idea what to expect except from what I read and saw on FossilDad's thread about his adventure with his daughter to this site. What they found last year must have been the last handful of pieces to be found. However there was a gift from the Fossil Fairy the moment I summited. There in from of me was a full horn coral just laying there. No mistaking the little curved funnel and pattern on the top. Is it red? I don't know. It's still in the bag yet to be cleaned. The time allotted was just under 2 hours to search the exposed areas. Several opinions formed as I wandered looking for something I was not familiar with. Everything was gray, not much red of anything showing. Very, very few if any cylindrical Horn Coral shapes. Here and there were bits of red agate chunks and coral chunks. I picked up both and kept the latter. I scoured 75% of the summit area including the more recent pits found all over, the debris piles, the larger taling piles from a bulldozer and pretty much flipped a bunch of rocks. I was hoping also to find something in the matrix. I did...all busted up stuff. Opinions were randomly formed. "This place is a mess". Pull tabs were everywhere - " A lotta people have been here for many decades." 1975 was the last year of pull tabs. Yet there they lay. That many years and more and that many people - "This site is picked over". At least as far as surface finds go. Digging violates the Mining Claim rules, I do believe. Another opinion arose -"Check the box, Steve" "This is no longer a viable site without digging". "The only way I would go back is with the owner giving me written permission to dig." That's how I saw it. A great excursion all and all. The cows were friendly, I saw two Elk skeletons on the way up, I found some goodies, no injuries...but my knees are stinging a bit, The very first whole Horn Coral specimen was the cherry on top and I got it right when I summited. No AMS, surprised me. I slipped on a cowpie while trail running down. Glissading a cow pie. Now that's something I can check the box on. Didn't fall either. Here's a pic or three. More tomorrow when I clean the goodies a bit. One piece looked like a chicken bone, not horn coral but some kind of coral, I think. And finally a rock for my mountain climbing summit collection - Location, altitude and date are written on them and in the case they go. Steve Washed out recently from a pile is my guess. Maybe, maybe not coral. Not Red Horn Coral... Two for sure! A bowl of unknowns. The target practice shed on the summit. The aftermath. Probably 25% cow pie coating.

A good number of Dinosaur collectors, on this Forum, have Acrocanthosaurus on their wish list and its one of the holy grail of teeth to acquire. I saw this post by Jim Kirkland and thought I would increase the drool factor. He does not state what formation it came from but have to believe its the Cedar Mountain Formation.. Enjoy His comment "Acrocanthosaurus serrations are so fine you can barely see them"

I found these two rocks in BLM land around the Ding and Dang slot canyons, which are close to Goblin Valley state park in Utah. I believe that they are both some sort of fossilized bacterial colony, but I'm not sure. The two possible fossils are made of different types of sandstone, as seen in the deferent shade of color. The larger one: The smaller one: Additionally, the smaller one has a barely visible mineral layer (gypsum?) running through it, seen below. Could anyone please help me identify these two possible fossils?

My friend found this awesome fossil in Utah. Can anyone discern what it is?! It's pretty big

My 1st attempt at asking advice got locked because I mentioned specific sites. Sorry! (Mods please delete that one if possible). But I'm not even looking for advice about WHERE to go. That's already decided. We are going to a trilobite quarry in Utah and a Green River Formation site in Wyoming. We've never done this before and are driving a LONG way, so I want to be as prepared as possible. So if anyone has any helpful advice for first-timers so we can make the most of our one chance, we'd love to hear it. Thanks in advance!

My wife and I will be making our first trip out to Utah (U-dig, trilobites) and Wyoming (American Fossil, GRF fish, etc.) later this month and are very excited to finally experience these places. If anyone has any advice for first-timers we'd love to hear it. Thanks in advance!

I found this near Logan utah, I have another “bone” fossil I found there that I would like to post also. A hater told me it was natural who looked at it in person. I just want to know. I am a proud rock hound. This seems odd to me. I found several horn coral fossils and sea life proof near by. This would have been near a lake bonneville shore at some point. The surrounding seems very sedimentary while the inside seems agatized. Following what looks to be an actual foot and not a print seems you can see the actual outline of how a toe was curled into the mud. There looks to be a total of 3 toes but doesn’t look to be all forward facing by Dino prints I’ve seen so maybe big bird or just the way it laid to rest. I need help please!

I was finally able to make it down to Delta to go to the U-Dig Quarry and have all my mudbug dreams come true. While the husband and I didn't make any huge or groundbreaking finds, we did come home with about two Home Depot buckets full of loose trilobites, mortality plates, and big chunks of shale ready to be split. I decided to try my hand at prepping some of the loose bugs using a stainless steel brush and a dremel. The first victim: before And after. I'll admit that I was nervous that the brush would scratch up the trilobite, but it seemed to come out pretty okay. So I tried it again. Before. After. I can't wait to clean up everything else, and I can't wait to get back out there and hunt some more! I just wish this wildfire smoke would subside... Happy hunting, everyone!

Hi from Utah! Looking forward to learning from everyone here.
luokiteltu posted a topic in Member Introductions
Hey guys! Just starting to go down the rabbit hole of fossil hunting and prep after my first fossil hunting trip out in the desert of Utah. Found some neat fossils (Hemirhodon Amplipyge, Olenoides Superbus, and a few others) in the Marjum formation. Who knew you could just go out and find fossils! I just got myself a little sand blasting setup, and I'm trying to learn how to use it. Would appreciate any advice you guys have on how to clean these fossils or learning how to use a sand blasting setup!

Forum member’s new book on Four Corners region includes stories of its paleontology
Sagebrush Steve posted a topic in Members' News & Diversions
I’ve been retired for a few years and needed an excuse to get back out to one of my favorite places, the Four Corners region of the American Southwest, so I decided to write a book about it. That way I could tell my wife “I need to get out to Canyonlands to collect information for my next chapter, see you in a week or so, bye….” It’s taken a couple of years (an unexpected challenge during the pandemic era), but the book has just been published. Titled “The Slickrock Desert: Journeys of Discovery in an Endangered American Wilderness,” it uses stories of my personal journeys over the last 40 years to introduce the reader to the region’s history, natural history, geology, paleontology, and what we know of its earliest inhabitants. Paleontology is only one of many topics in the book, but I do include several stories of recent interest in a couple of the chapters. One chapter tells the story of Dr. Alan Titus, at the time the paleontologist for Grand Staircase-Escalante National Monument. In what he has called "the find of a lifetime," he somewhat accidentally discovered a whole family of fossilized tyrannosaurs jumbled together at a site now known as the “Rainbows and Unicorns Quarry.” Dr. Titus and his colleagues have put together a convincing story of how this quarry suggests that tyrannosaurs hunted in packs, which would have been a terrifying proposition for the herbivores of the day. I had the opportunity to interview Dr. Titus, who corrected some of the information I had read in the trade press that wasn’t quite right. I also share the story of Dr. Martin Lockley, generally considered the world’s expert on dinosaur trackways. He’s not only an expert on the trackways of the American Southwest, he’s also a recognized expert on trackways throughout the world. In 2020 the Republic of Korea awarded him their Presidential Citation for his many contributions to research on trackways in that country. The book is intended as a general introduction to the Four Corners region and covers many topics, so I can’t delve deeply into any of them. But given that the Four Corners region is rich in paleontology I thought I’d share this with forum members. It’s available in all the usual places. If you have any questions send me a PM. Here’s a picture of the cover. Thanks!
