  1. Hi, so my grandpa gave me this and we both have absolutely no idea what it is. He does not remember where he got it from, so I’m sorry about that. The fossil itself it very smooth but has slightly raised ridges that go along it vertically. The hole does not go through it, but about 1/3 of the way down. We started to wonder if it is perhaps a bone fragment that just got fossilized but that’s why I’m here. Hopefully the pictures I took can help. It’s okay if no one knows, just wanted a general idea. Thanks in advance

    Couple of bones

    First bone is modern from Trinity river so this for the sake of learning, assuming it is a Tarsometatarsus, my question is how can you tell if bone is from waterfowl and how hard to determine bird species? The dark bone is from Cretaceous Woodbine and I'm not familiar with preservation on them, this one is funky, scratch it with fingernail and it's powdery, might be modern and hoping it's not too worn for ID. Thanks for help!
  3. Hi can anyone tell me what this is? I've no idea what it is or where it's originally from, I'm assuming it's a fossil? My grandmother passed away a few years ago and it was amongst her possessions so we've no idea where it came from, however, it has a drilled hole running through the middle and its been polished, so at some point in the past it looks like its been worn as jewellery. Her father was a merchant sailor and so she had a number of items from around the world, so really it could have come from any country. Can anyone help?

    Mazon Creek ID help and/or confirmation

    A0009 -- Plant debris? The middle part resembles Taeniophyllum latifolium. C0007 -- Cyperites or something other? C0051 -- Root? Radicites gracilis or other? C0083 -- Calamostachys sp. or something else? As always, any help from the usual gang is greatly appreciated. @bigred97 @connorp @deutscheben @fiddlehead @Nimravis @RCFossils @Runner64 @stats
  5. Unsure of what I have found. Hoping for some help.

    This piece was in a collection that I purchased earlier this year and I just noticed it, but have no clue what it is. I have no information at all on this piece. Any help would be appreciated.

    aurora unknown

    There was a post asking about bones found in the aurora museum fossil dig pits. Mostly I have found dolphin vertebrae, and assorted shark teeth and lots of unidentified bone fragments. I dont know what this is , it looks mostly complete and has some obvious muscle attatchment sites- I was thinking humerus but the broken surface has a flat articulating surface. Help will be appreciated

    Mystery fossil

    I would like best guesses on what this fossil is. It was donated to the NHM with no information or provenance. Maybe it is a fish? Looks bony.

    Can anyone identify this fossil?

    Hi! I was out looking around the local area and happen across this fossil. It's anyone able to identify what exactly it is I found? Thanks in advance.
  12. Found this on a FossilID subreddit. Could this be an asaphellus fezouataensis?

    Another four more Mazon Creek for ID

    And another four that I need help with. Thank you in advance. E0021 - Pecopteris? Other? E0040 - Mariopteris? Neuropteris? Best guess? Venation not clearly visible. E0098 - Cyclopteris obicularis? This one I'm fairly sure of. I0002 - Paleocaris typus? Acanthotelson? Other?

    Funky stumpy shark tooth & an unknown

    Both of these from Eagle Ford Post Oak creek matrix, I didn't even recognize the tooth on first look, not sure ID is possible but curious is it very worn or just emerging or what? The other item looks like it should be something but may be ironstone, just not sure.

    Mystery Huge Anomalocaris Appendange?

    Hi, I have this mystery piece of what appears to be anomalocarid appendage of sorts. The problem is I did not receive any information with it and it came out of an old collection from Maine, Usa. I'm not to sure what else it could be from the appearance but I am also very uncertain of the exact species. The piece of a very laminated sparkly shale If I had to guess it could've came from either Burgess Shale, Utah, or Nevada but I not sure what locality it could be from so if anyone if familiar with these shales and can tell from the preservation it would be a huge help, thank you and looking fo

    Ordovician echinoderm....?

    Upper ordovician, Italy. Decalcified specimen (it means that you see the mould). Scale bar 5mm. These are 3 different specimens, but I guess of the same species. At first thought they seem a blastoid oral area (never reported blastoids from this formation). But, as 2 of 3 of these specimens are inscribed in a circle, I was thinking about a particular echinoderm stem mould.

    Optics part?

    I mentioned this here and have had it a long time. Tube with green target lens no markings. Possibly a surveyors instrument part. Green target that rotates. I coupled it to my phone and then did a grey scale image. Any ideas on maker or use?
  19. Hi , I was wondering is this rock a fossil i found it at this location in Sentosa I found it at Sentosa

    ID'ing a potential fossil

    Hello there everyone! I found this site while looking for resources to ID what my wife suspects is a fossil. We acquired it cleaning out a house that was bought 'as-is' by a relative. - it was on a brick fireplace with some other interesting rocks including a huge piece of obsidian. She swears it looks like a dinosaur egg. I don't see it but agreed to look into it. It's about 10 inches long by 5 inches thick at the thickest point and shaped kinda like a football. Thanks very much for your time and expertise.

    Unknown Fossil

    Hello, I'm new here and this is my first post. I found the fossil at work today laying in the gravel. I'm not sure if it came in on a dump truck load of gravel or was unearthed 4 years ago during the construction of the impoundment ponds. Regardless it was found in northeastern Oklahoma approximately 45 miles directly south of Tulsa. The only thing I can tell you about it other than what the pictures show is the smell. It had the smell of oil shale after I rinsed the dirt from it. I tried to meet the requirements for photos but I have no ruler that measures in MM nor do

    Mazon Creek Nodule Unknown

    A Mazon Creek nodule popped open a few days ago. At first I thought it was nothing. But in the right light, I have hope (hopefully not false hope) that this may indeed be a find. If this were my Ordovician matrix, I could envision a trilobite. Maybe it mimics a horseshoe crab!!!! During my hunt, I did get to see a horseshoe crab found by @flipper559 I will cross my fingers waiting for the experts to respond.
