Bone of some kind. I've not seen this type shape so don't even know where to start looking . The bone was found in a rock pile appx 20-25 feet off he snake River in Hoback, WY. This was found on private property and with owners permission. Any help or direction would be appreciated.

Found a couple interesting items, on private land and with owners permission, in a rock bank about 15 feet off the Snake River in Hoback Wyoming. The shape looks like part of a hoof but I know shapes don't always tell the true story. Any help identifying, even if purely geological, would be appreciated.

Having a blast in Wyoming. Not a lot of success in looking for fossils but didbcome across a nice hash plate. Only a few more days to look but the reservoir is extremely low in anticipation of snow melt so have fingers crossed.

Dear members of the fossilforum, I recently acquired this caudal vertebra of Camptosaurus dispar. the fossil label is as follows: Camptosaurus dispar, caudal vertebra Upper Jurassic, Morrison Formation From channel deposit near Bone Cabin Quarry, Albany County, Wyoming. Found by employee of Quarry lease owners. The questions I have about this fossil are: - Does anyone know the name of this channel deposit? - Does this vertebra look like it came from the Brushy Basin Member or more like it came from the Salt Wash Member? Thanks in advance for your answers, Sander

I was wondering if anyone could help ID this coral. A friend picked it up from a Cretaceous marine sediment in eastern Wyoming. The individual pillars are roughly ovular but it could be taphonomic

These camarasaurus metacarpals were discovered within a 20' area of the digsite. A number of other camarasaurus bones were found in the same area. They all came from a smaller, sub-adult camarasaurus. I'm trying to figure out if they all come from the same foot. (left, front foot) I have only two, or three worn out toe bones, and the big claw was missing. High energy water ripped this dinosaur apart. Parts of a diplodocus were scattered around the same area.

I just couldn't resist purchasing this Knightia, from the Green River Formation in Wyoming from a local craigslist seller. Yes I do troll craigslist a lot looking for all the coolest gadgetry. Well the lady I bought it from said it was gifted to her and that she had no clue what it was and didn't want it. She sold it to me for $10. I plan on taking a trip to the Green River Formation but just in case I don't make it out I decided to get this 7" beauty.

Hi all... One of our students found this in Cambrian Gros Ventre Fm of Wyoming. Wyoming trilobites are pretty rare. I plan to make this the Fossil Of The Month for out Tate Museum newsletter but I need help IDing it. All of you who help me ID it will get credit in the Newlsetter. It is about 2cm long. I know there are some trilofolks on here who can convince me it is a so-and-so. Thanks, y'all.

Hi fellow Forum members. My wife and I are planning a collecting trip to Utah, Idaho and Wyoming the last week of June and first week of July. We have a condo in Park City. This will probably be a one time trip so we want to make the most of it. So far we have added U-Dig in Antelope Springs, Utah, and are planning on visiting Spence Gulch in Idaho. We are also looking at fossil fish collecting in Wyoming. My question is this; 1) Can anyone recommend other collecting localities in Utah for trilobites and/or Gogia? 2) Does anyone know if the Riley Canyon agatized horn coral site is still worthwhile? 2) There are several pay quarries in Kemmerer, Wyoming to collect fossil fish. Any thoughts on the best location to go? 3) Does anyone have more detailed directions for finding Spence Gulch in Idaho? I have a Google Earth map but am not sure how accurate it is. 4) Is there someplace we just shouldn't miss? Any help would be greatly appreciated. Thanks, Andy

I'm currently working on a very bulky bone plate, and cleaning up a camel ankle I repaired. Thought you guys might like seeing some of the work. The long bone (I believe it's the 3rd metacarpal) is 4 inches long.

Hello, I bought a small fossil that looks like a small eel fish. Is it just a knightia from a top angle? Or is it something else? Also the back part of the rock was revealing a small brown spot. I got curious and started chipping away and I found another fossil! That one looks like a knightia eocaena but since I'm so new I can never be too sure. Help will always be appreciated!

Amyzon is a Catostomid fish so far known from most of the Lake Gosiute localities but not in Fossil Lake deposits or Lake Unita deposits. Taxonomy from Mindat.org. Diagnosis from Grande et al. 1982, p. 524: "A species of Amyzon which differs from all others in having the following combination of characters: body depth 36 to 44%, head length 29 to 33% of standard length; 22 to 24 principal dorsal fin rays; 34 or 35 vertebrae (including Weberian complex); long pelvic splint (unsegmented bony ray) about 50% or more of fin length. Of the six previously described species of Amyzon, A. gosiutensis most closely resembles A. aggregatum Wilson (1977) from British Columbia. Meristic and morphometric data for these two species are presented in Table 1. Amyzon gosiutensis differs from A. aggregatum in having fewer dorsal fin rays, larger maxilla length/standard length ratio, and larger preanal length/standard length ratio."

Asineops squamifrons was first described by Cope as having an affinity to the pirat perch family. Later, with more detailed study, this species was found to lack the diagnostic characters of that family. Thus it is not yet clearly assignable to order. Although this species is much rarer in the Fossil Lake sediments than in Lake Gosiute deposits, the specimens from Fossil Lake are much larger than those from Lake Gosiute.

I need help to indentify a fossil found at Fossil Butte, Wy. I found it about 20 years ago while on vacation with family. The guide was telling us how to open the rocks and being a typical teenager, I just randomly grabbed a rock and broke it open. The guide couldn't indentify it and my grandmother does still have the other side of the fossil. My wife and kids think it's cool, but with led love to know more about it.

Hi- Looking to confirm the ID that I have on a partial lower left jaw of a mammal that I collected years ago in the White River Formation of Converse County, Wyoming. I have the jaw ID'd as "Stibarus", just looking for confirmation. The scale of the pics are 1 CM squares. Thanks

New Kiwi-like Paleognath Bird Discovered In The Green River Formation
Anchiornis posted a topic in Fossil News
Calciavis grandei: An awesome new Green River bird species for all you fossil hunters in Wyoming! Palaeoart (by Velizar Simeonovski) From SciNews: "A nearly 50-million-year-old bird fossil unearthed in Wyoming represents a new species that is a close relative of living kiwis, ostriches, and emus, according to a team of paleontologists from the American Museum of Natural History and the Virginia Polytechnic Institute and State University. The ancient bird, named Calciavis grandei, is believed to be roughly the size of a chicken and was mostly ground-dwelling, only flying in short bursts to escape predators. “This is among one of the earliest well-represented bird species after the age of large dinosaurs,” said co-author Dr. Sterling Nesbitt, from Virginia Tech. The exceptionally well-preserved specimen of Calciavis grandei dating from the Eocene epoch — with bones, feathers, and fossilized soft tissues — was found more than a decade ago in the Green River Formation, a former lake bed. The Eocene lake is best known for producing scores of complete fish skeleton fossils, but other fossils such as other birds, plants, crocodilians, turtles, bats, and mammals from an ecosystem 50 million years old. According to Dr. Nesbitt and his colleague, Prof. Julia Clarke from the American Museum of Natural History, Calciavis grandei belongs to the extinct group of early Palaeognathae birds, the Lithornithidae. The bird is a close relative of the modern-day kiwis, ostriches, and tinamous now living in the southern continents." Full article at SciNews. Research paper from the AMNH. Fossil:- 6 replies

Taxonomy from Grande & Bemis 1998. Species diagnosis from Grande & Bemis 1998, p. 189:" Amia pattersoni sp. nov. differs from all other known amiine species in the following adult characters A through H. (A) The number of subinfraorbitals (four or more) is higher than in any other amiid. (B) The gular is longer and narrower than known in any other species of Amiinae. The center of ossification of the gular lies within the posterior half of the bone (indicated by ornamentation pattern) unlike †A. "robusta" where it lies in the middle of the bone. (C) The frontals are narrower than in any other species of Amiinae (width-to-length ratio = 0.31-0.36, Table 41, compared to 0.47-0.65 in A. calva, Table 2; 0.43-0.49 in †A. scutata, Table 21; 0.36-0.37 in † "A." hesperia, Table 31; and 0.40-0.55 in †Cyclurus, Tables 50, 60, 70, and text). (D) Mandible is longer than known for any other species of Amiinae (mandible as 7322 percent of head length is 69%-71%, Table 40, compared to 56%-68% for A. calva, Table 1; 59%-66% for †A. scutata, Table 20; 62% for t "A." hesperia, Table 30; and 51%-65% for †Cyclurus, Tables 50, 60, 70, and text). (E) Number of dorsal fin rays and radials differs from that of any other known Amia (45-47 segmented rays and 44-48 proximal radials, Table 48, compared to 48-51 segmented rays and 49-52 proximal radials for A. calva, Table 16; 51-53 segmented rays and 51-54 proximal radials for †A. scutata, Table 28; and est. 40 segmented rays and 39 proximal radials in † "A." hesperia, Table 38). (F) Fewer abdominal centra are present than in any other species of Amia (30-33, Table 45, compared to 38-40 in A. calva, Table 11; 33-34 in †A. scutata, Table 25; 32 in † "A." hesperia, Table 35). (G) The absence of the lacrimal notch. This notch (for articulation with the first subinfraorbital) is usually present in all other species of Amia. (H) The posterior margin of the opercle is sigmoidal, bulging convexly along the lower half and slightly concave along the upper half, unlike all amiines except for †A. "robusta". Characters B, C, and D above are correlated with an elongated skull in this species." Line drawing from Grande and Bemis 2002, p. 186; References: L.

I have a couple of interesting fossils collected in green river formation. The first is from just below 18" layer and I have been thinking it was a leave, but the form is odd with large dark center section and now I am wondering if it some type of seed or fruit? It is about 3/4" long. Any thoughts? The third photo is of a fossil collected from split fish quarry and it looks like a seed or nut to me (almost similar to a pistachio nut), but perhaps just my imagination and it is some collection of fish parts or other. It does like there is the start of another similar shape just to the right of this. It is about 3/8" long. Thought I would also add photo of an insect collected with the first fossil . It is a Plecia Pealei and just looks nice with the wing structure visible.
