Hello, Can someone help me identify these two Didymoceras pieces to the species-level? They are from Montana and both were repaired from a few fragments, though neither is said to be composite. From what I can tell they are in the 10-15cm range in terms of size. 1. This one seems to be part of the inner whorl, and based on how close the coil is I think D. cheyennense might be excluded, which leaves either D. stevensoni or D. nebrascense? Also in the 3rd photo there is a strange mismatch between the fragments...a poor fit or composite perhaps? 2. This looks like a section of the inner whorl lower closer to the living chamber. Any help would be appreciated, thanks!

Here is the complete guide to the Mahantango ammonoids! Koenenites is only included because of two specimens (found by my friend and I) from Swatara Gap, which includes some Mahantango strata according to HynerpetonHunter. Tornoceras is the most common, Koenenites the rarest. Enjoy!

Hi, new here and looking for some help please. This was found at Aust Cliff bone beds, sorry no scale but its close to 40mm wide at the base. Can anyone help identify what it is please? Thanks, Chris

Would love to know what species I have here. The trilobites are in a fine grained sandstone or siltstone, approx. 1 to 1.5cm. The plant fossil is in flaky but rigid shale, It did break coming out and you can see my snarge repair job with some black glue. The largest fern frond itself is about 6 to 7 cm but similar smaller impressions are all over the piece, inside in different "layers" of the shale and on the reverse side as well. Trilobites found at Swatera Gap roadcut on I-81 in PA, the fern is found in the Glenshaw Glass RR cut off of Rt. 8 in Etna, PA. (just 7 miles north of Pittsburgh)

Hi Forum, last week me and my little brother (9 years old) went to the Omhden (DE) quarry for our very first fossil catch! I'm new to the 'dig&find' activity and to the fossil identification i found some good ammonites, apticus, belemnites and some shells. I have a doubt about this specimen. I can't tell if it is a bad preserved terminal part of a little belemnite or a tooth. The vertical fractures that i can't find in other belemnites create me confusion... to increase my doubt, i found a beautiful Micropassaloteuthis Fistulata at the Holzmaden museum that looks pretty similar, but again without stripes. Total length 8mm Thanks a lot Paolo

Found in West Texas (Rocksprings, Texas.. Sutton county). Found this while walking a ranch. Pretty sure it's a bobcat mandible, but wanted confirmation since I'm new at this. Anything helps!

Wanting to confirm if this piece found in the Jurassic Coast is a fossil.
Dolan posted a topic in Fossil ID
I found this stone while hiking along clay cliffs in the Jurassic Coast England after heavy rain. Hoping to confirm if it is indeed a fossil or just an unusual looking stone. -
Hello, this slab is from the Kope Formation, particularly Upper Alexandria sub-member within Delhi Township, Ohio. I am unsure if these rounded "structures" are bryozoans, echinoderms, or brachiopods, but i'm leaning more toward bryozoans. Fauna on the slab include: -Cincinnaticrinus, Ectenocrinus -Retrosirostra OR Dalmanella (hard to distinguish) -Bythopora -Isotelus, Flexicalymene -Ambonychia If anyone has an idea as to what the round objects are, please comment! Thank you! EDIT: I now believe these are individual cephalopod chambers that were filled with hash. I credit a fellow UC student!!! Now I wonder if anyone else thinks similarly.

Hi All, I have a bunch of brachiopods that got separated from their data and was hoping someone here might be able to restore some of it. They are apparently Paleozoic and likely from the US midwest. I see probable productids and maybe rhynconellids in there, but my knowledge of brachiopods is pretty limited. I strongly suspect they are all from one locality. Any help with locality, age, or taxa would be greatly appreciated! Best, Carl

This was found in north Dakota This site has just been exposed there's been a 2 year drought and a lot of high winds , we also found Folsom points ,ultra thin halfted knifes , all made with knife river flint ,a lot of large preforms with Paleo flaking, points were sent to Jackson galleries and were authenticated as Folsom, This skull looks like it's from a very young bison , the way the horns seem to be bending is different from a bison antiquus , They look to be bending downward, Tip to tip it's 24 inches,

I was on the Oregon coast near Newport and found this really odd looking rock. I've scoured the internet and have seen nothing like it. Even the Google image search feature came up with nothing. Help!!!

Help! What is this? Botryoidal Hematite? A-A Basalt? Or WORSE?
Jellybean07 posted a topic in Rocks & Minerals
I found this in Starkville, MS and assumed it's ah-ah basalt, but was looking up different random minerals and "uraninite" came up. This couldn't possibly be a raw form of that, could it? They all came from the same place, a chalk-based cretaceous seabed. There was also marcasite in the chalk, not pictured. Some have some iridescence on the black glistening places, reminding me of iridescent hematite. I would love to learn what you all think! Thank you for your time

Differentiating Centrosaurine from Chasmosaurine tooth crowns?
Opabinia Blues posted a topic in General Fossil Discussion
I recall reading on the boards somewhere before that hadrosaur tooth crowns can sometimes be assigned to either the Lambeosaurinae or the Saurolophinae if enough of the crown is present. I was wondering if the same can be said for ceratopsid teeth? Can ceratopsid teeth from localities in which members of both subfamilies are known ever be identified down to subfamily? This question was prompted by both general curiosity and by the fact that I occasionally see isolated ceratopsid teeth sold down to the generic level (ie, one seller who has listings for Avaceratops, Judiceratops, and Medusaceratops spitters), and although I am almost certain you cannot make a generic-level identification of isolated teeth it does make me wonder whether or not these "identifications" could be based on subfamily designation? And if so, what's the diagnostic character/s for each? -
Hi any Ideas if this may be a meterite. Sticks to magnets. Metal is very hard seems to be harder than steel. When I do a streak test on the metal it's not what I expected it to look like instead of being a shiny metalic steak it is a very dark Grey Streak. When I put 22K gold testing acid or platinum testing acid on the streak the acid turns bright Yellow. The lower carat acids don't seem to have any type of reaction. I grinded of the end of the stone then used 1200 grit sand paper on my dremal to smooth the metal. So meterite? OR Meterwrong?

Over a year ago, I blindly purchased a large impressive-looking tooth from a seller who didn't even know its ID simply because it was cheap. On arrival it broke, and after consulting the forum and facebook groups, the general consensus was that it was fake. Even museum curators I respected told me that it was a crocodile tooth joined to a fake root by someone who tried to emulate a mammal one. Having been (apparently)scammed and feeling snarge lousy, I was >| |< this close to throwing the fake root into the bin. But one other collector who bought from the same seller was vehement we had something real, so I decided to keep this tooth a little longer. (Post continues below)

Hello. I found these on a Croatian island - they don't strike me as one of their regular Jurassic finds, as it appears to be more inside a fault of petrified red soil amidst the abundant limestone. They look kinda "new". Can anyone tell me what they are? I found them on two locations. Not a geologist, so no idea. Whale and other large marine life bones? Polished by the sea? After some seizmic event?

Before I post a trip report, I was hoping to get a few IDs that are giving me some trouble. First up are possible insects. 1. Crane Fly?? 2. positive and negative. Bee?? 3. Has the termite feel!! 4. Another Crane Fly Now what appear to me to be plant oriented material. 5. I am torn between three leaf clover (but how would that end up in a lake), or a flower, or a seed pod cluster. 6. Total unknown 7. Finally this confusing specimen. Great symmetry so must be something!

Picked this up on the foreshore on Mappleton beach (Holderness Coast, East Yorkshire, United Kingdom). I thought it looked like a poo and wondered if it was indeed a coprolite?
