    Help me ID!

    I found these at Holden Beach over Christmas break and would love some help identifying them! I know they are probably in the sea urchin family, but I would like to know more information about them if anyone has any! Thanks in advance.

  5. Hi everyone, does anyone know how I can clean this sea urchin and how to remove all the silicoclastic matrix?
  6. I published the book Fossil Echinoids of Texas last November. Since that time other people have come forward or found new species. I am currently working to add and addendum to that book. Currently in have 5 new species that will be included in the addendum. Included are 2 new Salenias (1 from the Weno and 1 from the Glen rose), 2 Cidarid spines, 1 new Tiaromma. If you have any Texas echinoids that might be new, I would love to study it (them) and if it is new, I would gladly add that specimen to the publication. Please give me a call and we
  7. I'd like to whiten a fossil sea urchin. Is hydrogen peroxide effective and harmless? I'm thinking 3%... any tips?

    Need a cidarid echinoderm ID

    I found this little jewel a while back, but never found out what species it is. Can anyone tell me what genus species it is? This is a close up of an ambulacral and pore area. I don’t think I can get much better on the close up picture quality. I do have a number of pics from other angles if needed. Thanks in advance for your input.

    Echinoid ID

    My son found these on the DPS trip to Oliver Creek. The hand out that shows some of what you can find list Epiaster Whitei. My son is giving the bigger one to his school science teacher to go in the classroom with the ammonite already there, so I need to make sure I put the proper information on the identification card I'm sending with it, so can anyone say for sure what these are? Thank you.
  10. Hi all, As well as being a great fossil enthusiast, I also love finding modern remains of life and nature. Like a few of you already know, I am also quite fond of seashells (fossil seashells are one of my favorite things). Minerals also interest me, though I don't know much about them. And anything else to do with nature will get me interested. I just came back yesterday from some fantastic holidays in Greece, and didn't come back empty-handed! At first, we stayed for a few days at one of our friend's house on the Greek island Paros. Then, we spent one night in Athens t
  11. Hello, I just found this strange rock on a rocky beach in southern Italy - Europe. The rock is flat and well levigated all around... the central part has some blackish shades... and as You can see has all those strange lines/spikes starting from center... at first I thought about a sea urchin... but what attracted me most are those ramifications at top of the spikes and in between them... this detail make me wonder if is some kind of plant... Is it a fossil or is just my imagination that makes me believe that? Thanks for the attention...

    What sea urchin is this?

  14. austinswamp

    teeth, snails, etc

    Good afternoon, I found these fossils in the Dessau Formation near Austin, Texas and have a good idea on most of them except the shark tooth. I am torn between Megalodon and Mackerel. Any ID on the others appreciated as well. Thank you
  15. Barasingha


    Sorry about the poor quality first picture but I am not able to currently take another pic. This was found in a Miocene area. Can you tell me if this is an urchin or something else? Thanks.

    How old is it?

    I found a whole shelf of these sand dollar urchins fused in sandstone on the edge of Coronado Island, in the San Diego Bay. Anyone have a clue how old they are?
  21. We visited the Wilson Clay Pit in Coleman County, Texas last April. My dad stumbled across this little guy, which, according to the Color Guide of Pennsylvanian Fossils of North Texas (McKinzie and McLeod) is Pronechinus sp., a rare carboniferous echinoid known only from the Wilson Clay Pit and Diyarbakir Province in Turkey. Here is a link to the specimen found in Turkey. Notice the same double pores on the ambulacral plates as seen in the specimen we found. Scale is in centimeters...

    Bottom of two Urchins were found in a creek that runs in north east Grayson co. Texas. I believe that they are in the Pawpaw formation, but could be Duck creek?
