  1. Dating Ammonite

    I picked this one up this morning, it was to nice to pass up and first one I ever seen local. My question is can you date these by the outer shell and how they are made up? Smooth or with ridges Etc
  2. Hello from ohio

    I had found this weird fossil working on my bosses cabin. Need help to identify what it is! I've had so many people tell me it's either a fossilized honey comb from a bee hive or a honey comb coral! I'm just confused and asking for help!
  3. Hello, I have a Phareodus Fossil. Its one foot long. I found it on August 12th of this year in Kemmerer, Wyoming. Today, I noticed something I would like some input on. I took a look at it and I noticed what looks like a pile of scales in the belly of the Phareodus. I am attaching a picture of both the full fossil and the area I am referring to. (I just noticed a Knightia is in the fossil also) I know Phareodus were carnivorous, and have big teeth, but what do you guys think? Are these scales in the stomach? Its last meal? Jared

  6. Recieved these in the mail today. I have several ammonites, no nautilus, and no polished ammonites. These arrived today and are absolutely gorgeous. I like the ammonite, but to be honest I fond the Nautilus absolutely stunning. Not certain if that is opal on the shell or not but it is gorgeous. Just thought I would share.
  7. Shark Tooth Identification Help

    Hi, I recently bought this tooth from a friend, but I am uncertain which species it belongs to. The root is very thin with great white characteristics, but the lack of serrations on the blade is more like a mako. My best guess is that it is a Giant White Shark (Charcharodon Plicatitis). It measure 2.75 inches. The last 2 photos show the tooth in comparison to a Great White tooth on the right side and a Mako Shark tooth on the left side of the tooth in question. What do you believe it is? Thank you for helping me out.
  8. Human bone?

    Found this by Brazos River near Sealy. Could it be human? Specifically, could it be a left tibia bone (left lower leg)?
  9. Hi all, I found this sea shell by a Malaysia beach. It was unusual in that of the thousands and thousands of "fresh-looking" shells around, this one looked incredibly old and felt more rock like than shell like. A museum staff examined this and concluded it is a Murex shell that's at best Pleistocene-aged but he admitted he isn't a specialist in sea shells. I asked the FB group, Fossil Seashells and got the following answers: 1) Chicoreus brunneus - Max 15 years - Fossils are found deep in sediments or on land in sediments, definitely NOT Fossil 2) Some scientists use the term "subfossil" for holocene specimens of species that still exist today 3) Old shell , probably a neonate in the 60's, dead in the early 80's, been rolling around/ used as a home base for a lot of marine life since then May I have your thoughts on this?
  10. First Fossil (I Think?)

    Hi all I found what I think is a fossil about three years ago in a stream of the Barrington Tops/ Dungog area of NSW, Australia. It has fascinated me since and I'm currently in the process of signing up to local fossil groups to learn everything I can about this hobby. Until then, any help in identifying what I have is much appreciated! Thanks
  11. Unidentified small radiating shape

    Hello all, Im new to this forum and new to fossil collecting. I major in biology and come from collecting numismatics for several years. I’ve found something very unique in paleontology, and that is immense age, which drew me to collecting fossils. The piece below was collected from Jebel Hafeet in Al-Ain, United Arab Emirates (quite high up the mountain). I’ve noticed two odd, radiating shapes (just below the mid-area of the rock). It’s about 10-15 mm in diameter. I’m not an expert in fossils but thought it looks too orderly to be classified as inorganic. Any advice would be greatly appreciated. Best wishes, Mohammed
  12. Ahhhh, this curiosity of mine... I am so glad that the folks on this forum love to teach and help a novice like me! The closer and closer I look at a rock, the more fascinated I am by it. I found what looked like a "plain old rock" today. (IS there such a thing?!) I cleaned it and started looking at it under a magnifying glass. There was a little hole in the rock, so I decided to try to see what was IN the hole. As I examined it, I realized that it was a bit like looking into a cave in a hillside. How fun! Of course that just brought on more questions, though. I photographed one particular area from different perspectives and looked at it even closer. I am not seeing the fan like bryozoan fossils I have seen in my other fossiliferous (I love that word) limestone - unless I am looking at it from a completely different angle (a possibility!!). From one perspective (the one I am posting here), there are two pieces that seem like they might have originally been connected - kind of like a shell of some sort that has a part removed from it? Like the curve might be broken? But the closer I looked, the more tubule like parts I thought I saw. So, here I am once again... Begging your patience and asking to glean from your vast experiences. This part of the rock is very small - I will add another photo of it with a ruler to show scale. I can include photos of the entire rock but I am trying to study this one tiny spot on it for now? Thanks so much for your help! Edited to add: Found in Huntsville, Alabama. I also THINK I see some crinoid fossils elsewhere on this particular rock, if that helps with classification. From what I can tell so far, we are in the Mississipian age? Ramona
  13. Fossil ID, pool area

    Hello guys, would you mind helping to identify two fossils I found in a pool at Brazil? The first one I believe is a firefly. The second one I have no idea of what it is.
  14. Dinosaur Park in Laurel, MD, is a tiny, 7.5-acre tract of county parkland surrounded by a business park in bustling, suburban Maryland. Nevertheless, it is the most prolific dinosaur and plant site east of the Mississippi. The first fossils there were found in the 18th century by slaves in the siderite (bog iron ore) mine that was there at the time. It wasn’t until 1858 that the bones turning up in the mine were identified as dinosaur remains. The bones found that year were from what would have been, if they a had done all the paperwork, the second dinosaur identified in the US, Astrodon johnstoni, which is now Maryland’s State Dinosaur[1] . Since then dinosaurs, turtles, small mammals, crocodilians, gastropods, clams, and tons of fossil plant material have been found there, all of it now at the Smithsonian. The site is part of the Arundel Formation, dating to the Lower Cretaceous, 115 mya, when the place was an oxbow lake. Tributaries were strong enough to wash dino bones into the lake. The fossils there are disarticulated wash-out. Whole skeletons are not generally found or expected here. The exposed hillside consists of a mix of fine grey soil, siderite bog iron and lignite (coalified fossil wood the consistency of charcoal). The lignite and siderite form a thin, dense gravel layer. The challenge for visitors and paleontology volunteers alike is to find the pale blue bones and shiny teeth in the cacophony of black and orange. Collection is done almost exclusively by surface scanning. If something large turns up by way of erosion, then they cordon it off and dig it out. Anything other than the wood is documented with the finder’s name and sent to the Smithsonian. Visitors may keep one palm-sized piece of fossil wood if they like. My husband and I met a friend and her two daughters there today. It was cold, but sunny. There were harsh shadows on the ground, which are supposed to make it easier to pick out shiny teeth. I find the contrast too harsh to see details. The park is open from noon to 4 every other Saturday. We got there close to 1 and spent a couple hours there, despite the chill in the air. I didn’t expect to find any exciting fauna. That’s usually our daughter’s job, and she was at work. I was engrossed in the lignite and the siderite plant impressions, hoping maybe to find a seed cone or two for their collection. Apparently, a handful in a day is not unusual there. I had no luck on either score. I did find a nice plant impression in the siderite. Looks like tree bark. I asked if that could be the one I took home. The volunteer looked at me sternly and asked, "Do you now what it is?" "Tree bark impression in siderite, but I don't know from which tree." “What do you do for a living?” “Artist.” “What do you do that will prove to me that this will be used for educational or scientific purposes?” I told him about my fossil blog and the homeschool paleontology series I just ran at my local library. He was convinced. Now I have it at home, but I may offer it to the Delaware Museum of Natural History, where I volunteer. Each of the girls also found something nice, albeit smaller, to bring home. Unsurprisingly, most of the other kids were disappointed because they didn’t find dinosaur teeth. There was a list at the registration table of maybe a dozen interesting things found today. As far as I know, no one found anything interesting while we were there. Some days go like that, but I was not disappointed. It was a good afternoon to see someplace new. [1] Maryland has both a State Dinosaur and a State Fossil. The State Fossil is a gastropod, Ecphora gardenera.
  15. Scute and spikes?

    Found in Bandera County Texas. Not sure of period, possibly found in a terrace deposit.
  16. Learned something.

    Hello everyone! So, a bit of a long story. I have a habit of looking at my fossils under a magnifier. Today, I was looking at a knightia fossil and I decided to theorize a little bit about it after looking at it. After looking at it for a little bit, I told myself that it looks like a sardine. After I did that, I went on the internet to take a look at the family of knightia as well as a family of herrings and sardines. to my surprise, my theory was correct. Knightia and herrings and sardines share the family clupeidae. You learn something new everyday! Jared

  19. Tiny Fossil

    Hello, I was organizing my fossils I got in Kemmerer, Wyoming, today. I stopped to look at a small Phareodus fossil I had. I noticed something I never noticed before. I took the fossil and put the odd thing I noticed under a magnifier. Picture it attached. I am not going to lie, it is TINY. It has ridges one one side as well as 7 lines coming from the dark part. Any idea what it is? Could it be a plant, or part of a fish? Jared
  20. Ptychodus tooth?

    Hi What is it? Age:Cretaceous, Touronian Location: Skałki Twardowskiego, Kraków, Southern Poland. The specimen was damaged during extraction. That is why it is glued.
  21. What do you use to back thin fossils? I have some nice pieces preserved in shale which came up pretty thinly. I'd like to reinforce to make sure they dont break. Thanks Liam
  22. Theese are from Evia island Greece an Upper Miocene site with fossils. Any idea what can be the oblong ones ? The cones are freshwater gastropods that can be seen. there is also round and some arced ones. Some have hole in the centre some not . The size also varies a lot from 1 cm to 10 cm
  23. Hey guys, first time posting here, just hoping you could help me. I bought a keichousaurus for €300 and It came today, but I only came across the fact that they could be faked soon after buying (panic). The seller was from a reputable online store and it was part of a well known private collection that was disbanded. It came with an authenticity cert and was guaranteed to be real. Looking at everyone else’s specimens I am slightly worried/disheartened about the condition of my own. It is painted heavily I realise and I’m wondering what everyone thinks of it. Is it worth keeping or should I try sell it? Feeling slightly disheartened as I feel like I’m not even looking at bone, just all paint, and Its been a life long dream to be able to have my own fossil like this. And besides, as a grad student, I paid a lot for it which really took a lot of budgeting so it all lands a little harder. Any (hopefully good) thoughts/comments are welcome! Thank you!
  24. Is it Ostracod fossil ?

    These are 2 photomicrographs (XPL and PPL) . Can somebody tell me if it is an Ostracod or no ? I found so much of this structre in different shape. Continental Limestone , Tunisia Thank you in advance !
  25. I have seen Ammos like this for sale but wasn't certain what the work on the end was about and wasn't certain if it was accurate or what not. Saw this pic on what I understand from here to be a very respected dealer's page and got curious. What is the point of the carving/opening at end of the chamber? Is it simply aesthetic or is it an accurate portrayal of the shell originally?
