    Urchin ID help please!

    I just came across these in my storeroom and have no idea what they are, well apart from an urchin of some kind! Any help is appreciated!
  2. Hello all. I just got back from an open day at a gem and mineral club. I picked up some fossils while I was there. Unfortunately, the mineral guys aren't so knowledgeable on fossils, so many were mislabelled and dont have information on them. I would love it if you guys could help me out. Ammonite from Morocco Two ammonites that come from Chile, I think... And lastly an urchin that came with no information

    UAE urchins

    Here are some eocene to miocene age urchins I found in Al Ain (part of the United Arab Emirates) near Jebel Hafeet. I would appreciate any id's. Some urchins might be a bit too far gone to identify. (underside)

    Conoclypus species?

    Hi, I will be posting a lot of my finds here. I would like to know if I could get a species identification for this conoclypus urchin. It comes from the miocene (I think so because it has nummulites in it) of Al Ain, close to Jebel Hafeet. It's the largest, and most complete one I could find. Unfortunately the bottom is completely gone, still one of my best finds though!
  6. What a sweet surprise! We found fossils then a bunker exploring our neighborhood, we’ve never been down the street before, but there was plenty of beach rocks used to maintain the service street to the windmills! Enjoy!

    Echinolampas hemisphaerica

    A rare echinoid originally described by Jean-Baptiste de Lamarck (1816) and identified as Clypeaster hemisphaericus. Found in the Department of Gironde. Lamarck, J.-B. M. de. (1816). Histoire naturelle des animaux sans vertèbres, Tome troisième [in full: Histoire naturelle des animaux sans vertèbres présentant les caractéres généraux et particuliers de ces animaux, leur distribution, leurs classes, leurs familles, leurs genres, et la citation des principales espèces qui s'y rapportent].

  9. I recently found a bunch of eocene urchins near Jebel Hafeet in Al Ain, United Arab Emirates. Most of them are a peculiar orange colour. The trouble comes when trying to expose the hidden parts of the urchin. When I remove the matrix, I don't see the orange color anymore. There's a grey layer that covers the fossil, which looks exactly like the fossil, but it's on top of the fossil. The matrix pops off of this layer. I don't know how to prepare this. Many of the urchins are only about as thick as a folded piece of paper, so I don't want to mess around too much with vinegar. A

    Urchins from Al Ain

    Hello, I found these urchins near Jebel Hafeet in Al Ain, United Arab Emirates. I think they come from the eocene, but I am not quite sure. I forgot to add a ruler in the photos, sorry, just know the largest one is just under 4 cm long. I would appreciate any id's. I will also be posting a picture on the fossil preparation section of the forum to see if I can clean them up a bit.
  11. I found this thing as a 10 year old in France. It is definitely one of my better findings on the flint coast there. I think it's an urchin but I don't have much knowledge about urchin and like fossils. Could anyone help me specifically what it is?
  12. Hi everyone, Sorry if this is a bit of a basic question, but I'm fairly new at this and seem to be finding conflicting information about what I'm looking for. I recently found a number of fossil urchins, and what I think look like will probably turn out to be shells enclosed in sandstone on a beach. Some are pretty clean and only have a small amount of sandstone adhering to them, but others are almost completely buried in the piece of rock with only little bits of the fossil exposed. I was wondering what the best way to remove the rock is without damaging the fossil? I've tried soaki

    Echinoid in rough shape

    Hello, I found this echinoid the other day, and I was hoping to clean it up. Unfortunately, it's in bad shape. This is the only one I have of this type, so I would like to make it presentable. I found it on Jebel Hafeet, Al Ain, UAE (United Arab Emirates). The fossil appears to be covered in calcite, plus the rock there is mainly made up of limestone. I heard that the "vinegar bath" isn't such a good idea, what else can I do?

    Echinometra mathaei?

    Hello, I recently picked up these fossil sea urchins. I think they're miocene in age. I'm not quite sure if these are different types of urchins, or if they are just in different stages of weathering. I put a modern "burrowing urchin" next to the largest one as a comparison. Found in Ruwais, Abu Dhabi, UAE (United Arab Emirates) on a beach with dredged materials on it.
  15. I have been contacted by the local historical museum which is looking for a prepared brownwoodensis urchin from the Lake Brownwood Spillway. Even though I live here I have never been able to successfully collect and prepare one of these. I told the local museum person I would try to help in the search for a suitable example. Can anyone point me in the right direction to find a specimen?
  16. Hello everyone! Just got home from my weekly vacation and started immediately the preparation. The matrix is soft, mostly loose sandstone and once wet you can process it easier. Right now I have no power tools, only some screw drives and picks. The process seems that will take a lot of time. Any advice is welcome. I also need advice concerning some issues. 1. One urchin that after making it wet, a crack was revealed. There is possibility that the crack expanded by half millimeter. How I treat that? Naturally dry it and application of 20% paralo
  17. Back in July of 2009, I was crawling around an Upper Cretaceous Eagle Ford Formation (late Turonian) site that was exposed by recent excavations. There were many amazingly preserved marcasite / pyrite encrusted ammonites and other fauna to be found. However, one of 'gems' of that site was a beautiful, tiny regular echinoid. I was fascinated with it and I made additional discoveries that I wrote about in an article on The Fossil Forum. (early images) In trying to establish an identification, I checked with several experienced Texas collectors and none of them recognized it. When that h

    Urchins from Charente

    Hi everybody, i found those pieces in A Kimmeridgian layer for the Cidaris and a Cenomanian layer for the other pieces and I'd like your opinion upon them. Kimmeridgian Cidaris : that's the fourth time I go in that place, I always found radioles but this time i come back with a piece of test. In the Cenomanian I found that urchin, I think this is a Leymariaster : This one is also an urchin according to me I think this is also the case for that piece but I'm not sure. @Coco, I did found urchins in Port des Bar

    sunrise disk in corkstone

    This block was on a pallet of what was called corkstone that i bought to use in a pond nearly 20 year's ago, I used the rest to border my koi pond but this one was too cool to pu into the water. i had it indoors for many year's but it got moved outdoors and developed a lot of moss, ,while it still looked cool i recently hit it with a pressure washer revealing more than had shown prior and since have become more curious about the center dis and cluster of spines. this morning I used a little sandblasting to erode the backside and this is what i have.

    Bartonian molluscs and urchins

    Hi everybody, i'd like to lighted by your opinions on those Bartonian fossils from Blaye on the estuary of the Gironde. Firstly, those urchins. Blaye is a place where exist endemic urchins. I made a little research on myself and found some names. Echinolampas burdigalensis ? (maybe sismondia for the upper one ?) 1) 2) 3) Echinolampas stellifera ? Those gastropods : Olividea ? Olivancillaria ? Terebellum ? Bivalves : 1) 2) 3)

    Found on a beach on Baltic Sea

    I found several interesting things while walking the beach last month just south of Visby, Gotland Island, Sweden. I wasn't even seriously looking, but these caught my eye. Three I can identify, but one has me scratching my head. It's been suggested it's a fossilized sea urchin, a bead from the Viking age, and perhaps a whorl used in spinning thread. All old, but I'd really like to know what exactly this little gem could be. It's about the size of a Cheerio, rock solid and smooth with a hole started on both sides.

    Puerto Rican sea biscuit?

    So i found this in san sebastian puerto rico and tried looking for info on it. All i found was that they were from madagascar. What's it doing all the way here in Puerto rico? How old is it? What period is it from?
  25. Hi guys, How are you? Just to let you know that I donated few fossils to 熊本市博物館 (Museum of Kumamoto city). The fossils I donated are a big nodule filled with danian ship worms from Amakusa Shimojima, a silurian piece of "coral" not yet identified from Yamatocho and my best (I won the FOTM contest with this beauty but its place belong to a museum as would say of famous archeologist ) Santonian sea urchin found in Amakusa. The Urchin should be part of the permanent exhibition as soon as they make some place for it. I will post pictures of t
