Good afternoon folks. I have what was identified as a Sauropod coprolite (1 of 5) from the Morrison Formation, Henry Mountains, Wayne County, Hanksville, Utah. Jurassic period (Per the seller's description). I purchased this back in 2000 and am requesting a verification so I can ensure my ID card is correct. All help is appreciated. Measurements are 8.5Cm W, 6.0Cm H, 4.5Cm D.

I'm wondering if anyone can provide a source or two on the geologic formation of "wonderstone" from Tooele County, Utah. I know it is volcanic in origin, but what formation and what geologic age? What overlies/underlies this rock? Do we know where and which volcano is responsible? Have fossils ever been found in there before? Google has not been excessively helpful in searching for this information.

A new Eocene bird species has been discovered in the Uinta Formation in the Uinta Basin of Utah. Dubbed informally as the Uintan paraortygid (yet to be formally named), this bird species lived about 44 mya and belongs to a family of extinct birds known as Paraortygidae that are related to living Galliformes (like chickens, turkeys & quails) and fossils from this group have been found in Europe, Asia, Africa & North America. The species is know from a coracoid bone. The authors state that these small ground-dwelling birds may have been competing with early mammals for resources http://www.sci-news.com/paleontology/uintan-paraortygid-08189.html https://www.mdpi.com/1424-2818/12/3/90 (Stidham, Townsend & Holroyd., 2020)

Florida - access to smaller creeks during rainy season
Mulletnsteps posted a topic in General Fossil Discussion
I'll start by saying I'm not looking for anyone's honey hole, but if you want to share please private message me. I'll be in Florida (Tampa/Venice mostly) with my family (coming from Utah) in late July/early August. Had hoped to hit up the Peace but I've heard it's no good because the water is high. I have 3 kids who love to fossil hunt and dig around for treasures so I'm disappointed that the Peace won't work out. What I want to know is if there are any safe spots in smaller creeks that I can access (legally) during that time of year and bring my kids for a few hours? Rather not do any guided trips, but would be ok to pay to access someone's land. We did the beach stuff (caspersen, manasota) last year and now looking to try our hand on a creek. Would be happy to give some tips on Utah spots in exchange for any info. Thanks. -

I just received confirmation from Professor Steven R. Manchester, Curator of Paleobotany Florida Museum of Natural History, that I do in fact have Bonanzacarpum sprungerorum! Special thanks to doushantuo's post (additions to paleocarpological knowledge:The Eocene) that restarted my identification quest and Paleoflor for encouraging me to pursue it. And TTF for giving me the venue to request identification assistance.

Good morning all. I have a fossil that was identified as "plant cross section(?) from Green river". I'm wondering if it's actually a fruit seed pod similar to Bonanzacarpum spungerorum species. It has similar form and shape. I applied a lite coat of easily removeable wax for protection.

Hello everyone, I found these oysters while driving by in Utah along Cottonwood Canyon Road. I would really appreciate any help on the species and formation they came out of. The outcrop contained a lot of black sand. Thank you. General pic:

I was recently in Park City, Utah, when I collected a few rocks from the dump of the old Thaynes Mine. I thought it was Quartzite at first, but then I did some research on the stratigraphy of the Park City District and began to doubt my assessment. From highest to lowest, the formations of the district are the Ankareh Shale, the Thaynes Limestone, the Woodside Shale, the Park City Limestone, and the Weber Quartzite. I am not certain of this, but I do not think the Thaynes Mine ever entered the Weber Quartzite. However, I did discover that the Park City Limestone contains some Quartzite inclusions, but I'm not sure if the mine even went that deep. Overall, I think that it is either Sandstone of Quartzite, but I'm not sure which, nor am I sure of the parent formation. Any input on this matter would be greatly appreciated. The specimen is a light bluish-grey, hard, fine grained, and has small pockets of carbonate residue in it.

Hello! Purchased this piece at a Gem and Mineral show. Seller had the item listed as an unknown dinosaur bone, and potentially thought part of a ceratops horn and acquired in Utah. Bottom looks almost suture like? Honestly, not sure. Got at a good price so it was worth the risk. About 5 inches tall, 3 inches wide, 2 inches thickness. Probably weighs 1-2lbs. Has been glued.

Hello! This is my first post/plea for ID help. This piece was found in the Summerville Formation in Little Egypt area outside of Hanksville, UT in the Henry Mountains (I believe Summerville Formation is middle to late Jurassic). You can see very colorful agatized portions showing through in a few places. Little Egypt is known for petrified wood (cycads, in particular), dinosaur fossils & coprolite, but there is so much misidentification of fossils in this area, so..... Thank you in advance for any help you can provide!

Hello everyone! My wife and I have been fossil hunting for a few years, so were still fairly new, but we have an amazing area at our doorstep. Hopefully we can find some amazing stuff to share with you all, and learn some things along the way.

Ammonites, Trilobites, Fossil Fish: Another Western Adventure
Jeffrey P posted a topic in Fossil Hunting Trips
Barely a month had gone by since my last trip to New Mexico and Colorado, but I already had plans for this trip in the works. Primary focus this time, which was a solo trip, was fossil collecting, visiting well known sites that have been on my radar for quite some time. I flew out to Salt Lake City and drove directly to Kemmerer, WY. My first stop there was Fossil Butte National Monument: Here is a view of the visitors center (free admission) and the surrounding barren, but awesome landscape that surrounds it:

Hello all, Before I post a ‘what is this’ query I’d like to see if I can ID seversl fimds on my own. I have a number of shells from the Mancos Shale near Moab. In terms of references I have Index Fossils of North America, and Invertebrate Fossils by Moore et al. The Index Fossils might have gotten me close but still, no cigar. Other sources I have are particular to ammonites. Can any of you suggest references I might find online that cover non-ammonite Mancos Shale fossils? Thanks, Tom

The Hunt for Jurassic Bivalves: A Short Trip
DeepTimeIsotopes posted a topic in Fossil Hunting Trips
Here is a small trip only minutes away from downtown Salt Lake City. If you would like the exact location, PM me. I hadn’t been to this site in a couple years so it took @Earth Chemistry and I a couple hours to re-discover it so here’s a little history about the area. Ok first, the structural geology in this area is quite famous as it is a large pair of synclines. From https://geology.utah.gov/wp-content/uploads/synclines.gif They were made in the Sevier Orogeny about 120 Ma to 50 Ma ago. -
I am looking to take my kids to go take for trailer lights and Utah but I'm looking for free places to do so on public land. Does anybody have any locations where I might be able to do this as a day trip?

Hi gang, I'm working fervently to prepare a post about the astounding time I had at Fossil Mountain in Utah during my fossil run back in July. (Will take me months to process and identify all these samples from four states.) I found a few partial trilobites at the upper layer of the Lehman formation, but I'm having difficulty identifying them. I freely admit I'm exceedingly weak at trilobites ID. these aren't the best pictures or even the best specimens, but I was there solo and the scree around the cliffs was pretty unstable so I erred in the side of caution. Anyway, Any suggestions much appreciated. I'll post better pictures tomorrow when I get my camera back off of my microscope at work.

I have lived in California most of my life learning how to prospect for gold and silver, decided I wanted a new adventure in my life have lived in Wyoming, Montana, and now Utah! Learning about fossils, and rockhounding! Very inexperienced but love an adventure! Brought to this forum by Misha we met on Instagram talking over trilobites, so far I have found some good things other then gold and silver, fossil fish, trilobites, fossil sea shells, a fossilized pine cone! Mostly about the adventure of finding things and working hard to get them!

Picture Heavy! On my first day in Millard County, I started out at the U-DIG quarry. I got lots of trilobites, but nothing too spectacular. (I'll share them in a separate post as there is quite a bit of prep work to do!) Honestly, I got a bit bored at the quarry. Sure, I enjoy digging fossils, but the challenge just isn't there. So after four hours, I decided to drive through Marjum Pass to Cowboy Pass. This is the view exiting Marjum Pass. (That is a truly epic drive on its own, but I didn't stop at any of the fossil sites in there!) Almost there! For those that don't know, distance and time behaves a bit strangely when solo in the desert. Finding road signs is even stranger. If you do decide to do a Millard County run, you'd better be able to use a topo map and a compass because you cant trust GPS maps and mobile phones have no service out here. I found that even the road atlas was untrustworthy. It took me three months of research to pinpoint the exact locations of the exposed Thaynes Formation areas of the Pass. Doing the homework paid off as I was able to find the "easy" site almost immediately. I'm not really into giving out exact locations, but I will say "The Book" is correct and accurate and that this photo shows the landmark referred to in an old Millard County rockhound guide. I know I could have just asked folks where they were, but a big part of this hobby for me is the satisfaction of confirming my research skills. One can easily drive to the "easy" site, but the other two (actually three...) require a pretty rugged hike. However, as you are about to see, it is well worth it. I found my first in the overburden some hack left behind. In fact, at the easy site I didn't even need to use any tools as whoever was there last ignored dozens of nice specimens! I will also add, I hope it wasn't someone from here...as I cleaned up all your %#!$%^&* trash for you. Three full bags of garbage and you left a virtually brand new gad pry under the pile of beer cans. Thanks. I needed a gad pry later! Anyway, Here are some of the specimens I collected from the various sites. Most of them need lots of prep work. Here's a few as they were found: I'll post more pictures at a later date as there is a lot of prep work to do on many of the specimens! So, in short, Cowboy Pass is well worth the excursion. Be prepared to do some real work, and study up on the site before you go. Also, don't be a jerk and leave a mess like the one I found...that is how public lands get closed to the public.

Okay so now that I have found a group of individuals to help me identify.... I would love to know what find of petrified wood I have collected.. species and mineralization would be helpful. I have stuff that I can't find online. I'll start with the first two that I can't even tell if they are wood or not... All help is incredibly appreciated. Found these two river tumbled pieces south of Green River, Utah. Jurassic I think? Very different from everything else in the field.. Looks agatized? Thank you! Trenton
