  1. 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

    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.

    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?
  4. 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?
  5. 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

    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. I have no way to know were it came

    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?
  13. 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

    Urchin spine

    Hi, several months ago i found a very tiny and rather flat urchin in a block which had two spines. I managed to disengage the urchin, but it is really too tiny for my camera. The spines are bigger and i wondered to what family of urchin they belong (maybe a cidarid ?) I also join the photos of the urchin that was with them (although i don't know if that would help). @Coco @caterpillar ? The smallest spine : The bigger :

    help, what is this urchin, egg, geode?

  17. I decided on a whim to go fossil hunting yesterday. I took off on the 2 hr drive to get to my favorite area the North Sulphur River Texas. I jumped off in three creeks to see footprints everywhere. I decided to go try a creek I spotted a few years ago but never tried. It paid off. I found my first NSR echinoid after 4yrs of heavy hunting. Echinoids are quite rare at NSR. I also found a really cool Pachydiscus ammonite with an Inoceramid on it. I think I"ll try that creek again in the future.

    Echinoid id

    Hello again, here is my most beautiful sand dollar fossil. We picked it up yesterday on a beach close to Ruwais, Abu Dhabi, UAE. I have found dozens of these, but rarely find one so flat. I would love to know the species name if possible.

    Sea urchin Holectypus?

    This was also found near Herznach in Switzerland and according to my lexicon, it could be a Jurassic Holectypus, am I correct? Greetings!

    ferns and urchin

    Hi everybody, i recently made an exchange and so i received those ferns, all i know is that they come from Colorado, i have no other clue about them. I also received an unknown urchin and have no clue about it. Could you help me know a bit more about them ? The longest diagonal of that piece is a little less than 15 cm, the base is about 13 cm and it is about 11 cm hight. @Plantguy @paleoflor ?

    what is this?

    I found this in a load of gravel that came in for the drive it looked very different from the other stones and stuck out. At first I thought it was a squashed fossilized urchin but after looking at it more closely I just dont know...I have included as many photos as I could get of the outer part ... then I have some of the open side....my question is is this an urchin of some type or could it be an egg???. Mon Sep 17 00-46-22....is the bottom of the item in question.
