Psittacosaur9's Cabinet Renovation Fossil Identification - Mesozoic and Cenozoic Animals Thread
Psittacosaur9 posted a topic in Fossil ID
Hello everyone, and I hope you've all had a good day. I started to put my display cabinet together today, and after an exhausting day of work, I'm only half done and I haven't even started on the bookshelf! Yay! Sarcasm aside, I've got some more fossils I would like identified, as I am creating labels for my displays. Just as before, I would prefer the most specific identification possible - species would be preferable, but I would rather a genus or clade name over an invalid species name. Location would be helpful too. Again, if any of you want them, I can take more photos tomorrow. Specimen 1: Actinopterygii This specimen I purchased at a museum, which simply labelled it as 'fish fossil'. While I do not know the location, I suspected it was from the Green River Formation in Wyoming, as many commercially available Actinopterygii fossils come from that site. At first, I thought the specimen was Knightia, as that fish seems to be one of the more common from the Green River Formation, and the only common one of the same size and rough shape. However, after recently observing a slab of Knightia at a museum, I began to doubt my initial identification, as the Knightia in the museum looked more bloated than my specimen. Is it a Knightia, or something else? Specimen 2: Ammonite I apologise for the rather shoddy attempt at editing out the supplier's logo. As you can see, I purchased this ammonite in a small plastic case at a museum, and cannot take a photograph of it from all angles. However, the back of the box (or at least what survives of it) says that the ammonite is Jurassic of age and comes from Madagascar (thinking about it, the supplier probably had to stick the ammonite to the case in order to get it through customs). Therefore, after comparing it to other ammonites from the same location, I believe it is most likely a Phylloceras specimen, as those ammonites lived in the correct place at the correct time, and had the same shaped, relatively smooth shell. Do you all agree with this conclusion? Specimen 3: Gastropod Another specimen I purchased from a museum with no knowledge of its original location or age. Unfortunately, I know very little about Gastropods, so I do not know how to identify it. Do any of you recognise at least what group it came from, or even tell its species, time period or location? Specimen 4: Ray tooth I received this tooth as a gift in a set of various teeth from Chondrichthyes. The gift set identified the ray tooth as Jurassic in age, however gave no further information on the specimen. To add to the confusion, all of the fossil ray teeth I have found available to purchase online come from Myliobatis, a genus which only evolved in the Cenozoic. While I am pretty sure it is Myliobatis and the gift set's information was simply inaccurate, I would like confirmation that this conclusion is accurate. Also, I do know that there is only half of a tooth; it broke a while ago and I no longer have the second half. Thank you for all of your help! Next up will be a couple of Triassic plant fossils, and following that will be some fossils I am concerned are fake. Hope you all have a good night!

I wish this was a post to celebrate an incredible accomplishment but instead I am extremely scared that through my potential carelessness, the likely greatest find of my life may be forever changed. I just a few days ago on 6/6 found this stingray fossil at American Fossil Quarry in Wyoming just and was able to keep it because it was at that location. I have been on a road trip and have been storing it in a plastic tote bin with bubble wrap and then fish fossils underneath wrapped in paper towel. I took the lid off for a prolonged period to air out the bin and I think this was a grave mistake and let in humidity. The paper towel was all heavily damp and many of the fish fossils had very obvious signs of mold/mildew growth and discoloration. And now I fear the stingray may show some as well. I desperately need advice on repair and preservation asap. I really need help trying to fix this mess as I’m still on the road for another week. It may not be super obvious in the images but it is the areas that appear a grayish color in contrast to the orangeish brown. The last image is the closest picture I took on the day it was found to show any potential change. This was a lifetime find and I will be crushed if I’ve caused irreparable damage. Please help. Any advice in repair and preservation is greatly appreciated. And I’m sorry to all those that see this and are disappointed in the poor handling of this rare piece, I’m more than disappointed in myself if things are what they seem. And if by a miracle the stingray is perfectly fine then any advice on the fish fossils would be great.

I am thinking of buying a fish fossil for my collection. These two look similar to me and they are all 13 cm. Just want to get your opinion, which one do you think is better? Thanks!! First one: Second one:

I am a complete novice to everything fossil-related. My family found an awesome fossilized asterotrygon on a huge beautiful slab with a couple of knightia. (That's my research talking.} I see that the overwhelming majority recommend butvar in a solvent, so that is my plan. It seems that all the posts refer to brushing it on. It seems, to me, like this would displace the tiny bones. ? I was assuming that spraying it on would be better. Could someone give me some advice on that? Also, I don't want the slab to split (it certainly has several splits on the edges.) Do I just apply the butvar to the fossils or also to the sandstone to stabilize and seal it? I included a photo to show the size of the sandstone slab.

Well, we've had Brachiopods and Trilobites, so I figured let's give fish a try! I am going to start this off with my Enchodus marchesettii from the Hakel Quarry of Lebanon. Not only is this fossil 100% complete with the only restoration done was repairing the matrix itself, but I received this from one of my good friends on none other than my birthday! This is my favorite fossil in my ENTIRE collection! More will come from the Greenriver side of my collection, I just gotta get my camera fixed

Hello all! This summer I took my yearly trip to Wyoming, and with my luck I again came back with several extremely incredible fossils! I found many less fish this time around, but I did find several more rare ones! I probably only found around 50 fish in the 3 days I was there. I found 8 Phareodus, including 2 juveniles! I found only 1 Mioplosus this year, the fish seems to be avoiding me sadly... I found 3 Priscacara, including a very large Priscacara serrata! I found an interesting Hypsiprisca preserved beautifully on an algea layer, also found several more Amia scales, but one of my favorite finds was a giant Amia tooth! (Though I suspect it to be gar) they said it was the largest one they had ever seen, and it is an excellent place holder for a future complete Amia! I also found dozens of shells! The shells especially the snail shells are considered to be one of the rarest components of the fauna, so it was very odd finding over a dozen! Including 4 mass mortality plates which each have dozens of shells on them! I also ended up finding an incrediblely incrediblely rare piece of bamboo, they told me that bamboo is rarer than a dozen stingrays! Speaking of stingrays, I FOUND MY FIRST ONE! A large Heliobatis that I split out almost perfectly! Speaking of rare finds, my absolute favorite find of this trip came as a surprise! Early in the day I found a very strange algea layer with several gastropod beaks, and I was excited as I thought I had found a Crossopholis. After having my heart broken I sulked over to a new pile of rocks and one my first split I found something very strange, a plate of small serrated scales! I did it! I found myself a paddlefish it's disarcticulated, but it still has a fin beautifully preserved! It's hard to describe the feeling of finding a Paddlefish and a Stingray the same day! I will be posting pictures soon! I will also be submitting my stingray whenever the prep work is finished!

One of the rarest and most unique fossils are aspiration pieces! I have been very lucky in acquiring 2 over the course of collecting, neither are incredibly good, but their rarity alone makes them that much more desirable! I would love to see anyone else's fish with eyes bigger than their stomachs!

Fossils range from 1.5 to 7.5 inches. Found in the last three years at American Fossil and Warfield quarries.

I scored some nice Eocene fish plates from the Green River formation in Lincoln County Wyoming. Can anyone help me ID these three fish? Any help is greatly appreciated.

A Dream Trip To The Green River Formation!!!
Mioplosus_Lover24 posted a topic in Fossil Hunting Trips
A few weeks ago, I posted asking for advice on splitting fish for Green River. Your advice helped me out A TON, so thank you for that . I ended up leaving with a shrimp, crawdad, 3 Pharo's, 8 Amphiplagas, both species of Hypsiprisca, and many more. But by sheer luck, we ended up finding a bird, which means, we're going back to Wyoming for a CT scan.(And for more splitting) According to Arvid, the bird appears to be a new species, slightly dis-articulated, but it still has it's skull. I'll post pictures of our finds when I get a chance, but I wanted to thank everyone that gave me advice.- 25 replies

Advice For Splitting Some Fish (Greenriver)
Mioplosus_Lover24 posted a topic in Fossil Hunting Trips
Hey, I am finally completing my dream-job at the American fish dig quarry!!! I am just looking for some advice from you Greenriver veterans! Any helpful tips, like what I should bring, what I should do, and where the best place too eat is when it is all over! -
I have a 1in long Notogoneus fry from the 18in layer of the Greenriver formation. For reference of the rarity of this specimen, https://www.nps.gov/fobu/learn/nature/fossil-fish.htm I am looking to trade this fish for more fish specifically Mioplosus but, I am open to all fish offers. I will also consider dinosaur material from Kem Kem or Hell Creek. Also sorry for the bluriness of the photos, I will get better pictures up ASAP.

Apalone Heteroglypta was described by Edward Cope in 1873 but was originally called Trionyx Heteroglypta. It was later renamed when a more complete skeleton was discovered. It is very distinguishable from all other soft-shelled turtles from Fossil Lake because of its rounded shell, and the near full loss of the eighth costal bones. It is a very rare find and is one of the most beautiful turtles from the Fossil Butte Member of the Green River Formation.

What is up with Lake Gosiute and Sweet Water Wyoming?
Mioplosus_Lover24 posted a topic in Questions & Answers
I am wondering why Lake Gosiute has been closed off to the public. It is the only part of fossil lake that has catfish and I really want to try and find one, instead of paying thousands of dollars for one. I have heard it was bought by a company, but I was still wondering if they would let a small private team dig or if they would sell any of the fossils. Thanks for any help! -
I made this chart about the Greenriver formation, and I was making sure I had everything right. I know I am missing 3 fish, but I could find no evidence of predation or them preying on any other fish. My conclusion was that Amia was the super predator!

I have been on the market for a large Mioplosus for about 3 years. The largest in my collection now is a humble 11". I was wondering if anybody knew someone that was selling or trading for a larger Mioplosus.(Preferably over 15")

I collected some nice fossil fish from the green river formation of Wyoming today. Can any experienced green river hunters tell me the best way to prep these fossils? One of the miners at the quarry told me to do a 80% water 20% glue mix and dunk it in the water quickly to seal it or it will eventually fall apart. He said not to use elmers glue but didnt say what type of glue. Also I have other specimens that are partially covered. They were telling people to use an exacto knife. to prep them and uncover all the fossil. What is the best way to go about this?

I rescued this fossil in the most unlikely place. The trash. I was walking along in a rock shop a couple of days ago looking at some cool meteorites when I noticed a trash can with a rock sticking out of it. I got closer and took it out and saw it had a fossil fish in it! I was completely astounded that someone would throw something away in the garbage! I took it home and showed it to some friends of mine who specialize in fossils. They concluded that it’s real and genuine. The fossil depicts a fossil fish that is oddly twisted and bent for some reason. I think this fossil may be from the Green river formation in Wyoming. The fish also might be a Knightia, but I’m not completely sure. Note there’s a isolated vertebrae from a larger fish near by.

Just wanted to share the x-ray of a fossil we extracted this weekend at our Quarry. All we could see was the cross section and we were pretty sure it was an amia but this sealed the deal. Notice that it's jaws have floated back by the tail and will need to be removed and re-inserted back in the skull. These are very uncommon in our quarry so we were very excited. Enjoy.

Last season was a great season at the quarry. For those who dont know, our quarry is in the Fossil Butte member of the Green River Formation in southern Wyoming. We ended up with three turtles coming out. Two of them were large turtles, 48" (Apalone heteroglypta) and 52" (Chisternon undatum), and they were found stacked above one another, separated by only 7 inches, and a tiny little guy that is a new species. I will post pictures of these amazing fossils as they are finished up. We have Brock @ebrocklds doing the preparation work for us on these three amazing fossils. Here are pictures of the Apalone. You can see it took us a bit of time to excavate and collect all of the tiny pieces. It was in a large fracture zone in the rock. Enjoy.

This is a female Stingray specimen called Heliobatis radians and is one of only two species of ray from the Green River Formation. Like modern stingrays, this extinct genus had barbs on its tail. This one is known to be a female due to the absence of claspers used by the male in mating.
