  5. Psammechinus carolinensis

    These little echinoids, referred to locally sometimes as "cheerios" because they average about the same size as one. They are a relatively common find in the basal sands of the early Oligocene River Bend Formation, often in association with Rebecapecten trentensis. This specimen is one of my smaller ones; 6.1 mm in diameter and is cleaner than most. Many of these have a calcite coating with black and white sand granules on them. In the last photo; the group shot, it is the one on the upper left. The smallest in the case.

  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 can talk about it. I live in New Braunfels. Bill Thompson www.echinoids.com
  7. Took a little trip out to the Lake Waco Research Area a few days ago (which, by the way, will be off limits for 6 weeks unless you go get a permit before the second week of December). This was my third or fourth time out there and I definitely came up with my best finds from there to date. Got the usual pryitized ammonites and bivalves, 2 beat up shark teeth, 1 tiny fish vertebra, and lots of pieces of echinoids, possibly coenholectypus. I did find one really nice shark tooth by almost sitting on it, a couple of mystery ammonites, and finally got a complete coenholectypus. Saw lots and lots of cool epibionts on the bivalve shells. If anyone has any ID's, I'd love to hear them, especially the red rocks. Thanks!
  8. We found a couple of sand dollar fossils in a hard matrix. From what I have read today I can’t get the hard matrix off without some special air tools. What should I do to preserve the specimens?
  9. Samphire Hoe, Sussex, England

    Samphire Hoe, Sussex is not far from Dover and was created by dumping stuff from the digging of the Channel Tunnel. It is a wonderful nature reserve, has a small shop/café, access to the beach and chalk fossils are easy to find on the surface of the fallen blocks. Mobile phone service is a bit weird as my phone connected and said Welcome to France, but Dutch tourists there had English connection. Good job there is a pay phone. Here are just a few of the bits I took a photo of. Not completely prepped yet but you get the idea of what can be found. Some are micro fossils from the dust as chalk easy to break down or scoop up from the bottom of the cliff. 1 - common foram 2 - Ramulina foram 3 - Tiny tooth next to Tritaxia foram ( let me know if I have got my ID wrong) 4 - Fish scale 5 - Bivalve with encrusting bryozoa 6 & 7 -Onchotrochus serpentinus Corallite overhead view and of one end confirming not a serpula 7 to 9 - What I think is shed isopod skin, NHM could not ID it but then they sent it to the fish department.
  10. The two specimens below are from the Eocene of Virginia. I’ve collected this site for many years and not found anything similar. They look like they are pieces of an echinoid. I’ve never found an echinoid, echinoid spines or pieces of echinoids from this site or any other site in Virginia before. EDIT: I should have put this information in the original post. These specimens are from a marine formation. They are very thin, almost paper thin. Yet they are hard and not flexible. Specimen 1 6mm x 5mm Specimen 2 5mm x 2mm Marco Sr.
  11. Coenholectypus?

    Found this little guy while hunting today with my kids. I haven't found something like this since I was young. I swore I would find one soon...and there it was! I would have just called this a "sea urchin" but I'm trying to learn more. I also don't want to simply just be told what it is, so I'm looking in books and doing internet searches. However, I'm either confronted with terrible printed images (old books) or precise scientific descriptions like "all ambulacra identical with elongate and weakly conjugate pore-pairs adapically; subpetaloid" .... So I'm sure I'll be checking here quite often on new things we find! Anyway, this was in Austin, Glen Rose formation (or similar - cretaceous limestone, no doubt). It's ~3 cm in diameter. (I need to get the lens fixed on my camera so I can do better macro shots than an iphone...) I've also never "prepped" a fossil before. This had more limestone over the top surface that I cleared off. I need some serious work in this area, but I'm willing to learn the right way!
  12. Spined Echinoid

    A few weekends ago I went to Texoma with the family and found a bunch of crushed Echinoids. Looking at them today, I noticed that one has what appears to be the spines still remaining. That leaves me two questions: Are these spines? And how common is it to find them with spines if that is indeed what they are? As always. Thank you for the insight.
  13. Is this an echinoid?

    Picked this up out of the Dry Frio river bed near Uvalde, Texas Thought it was a sand dollar at first. Is this an Echinoid of some sort?
  14. Big echinoid

    Ok, what is this. I bought it about 20 years ago. Im sure its from Morroco and i think its some kind of Clipiaster? (spelling) Need some info so I can sell it. Dont want it. RB
  15. My Fathers old echinoid

    Can anyone tell me how old is this echinoid fossil? My father gave me this fossil when i was a kid. If anyone knows it will be nice.
  16. 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.
  17. Yaxley Fossils

    I went to Yaxley today, and after processing most of my finds I'm left with a few puzzles. I recently found an echinoid spine, and was wondering whether the first one below is part of an echinoid test, The second was picked up as a belemnite, but the cross section looks wrong, and I've seen echinoid spines in museums of a similar shape. The third bobbly one I have no clue, and would be grateful for any suggestions. I've called it Mr Bobbly. Finds are from Yaxley, UK, Jurassic, Lower Oxford Clay, Callovian. ETA: the order of the photos changed as I posted, the first fossil is the round black one in the images, the second is the very pale belemnite-like one, including cross sections, and the third is the long bobbly one.
  18. Rhyncholampas carolinensis

    Rhyncholampas carolinensis are not an uncommon find in the Castle Hayne Formation of North Carolina. However, they are often badly worn, broken or heavily encrusted with limestone. This little beauty is about average size and very clean. It also has a bonus "hitchhiker" a Polychaete worm. This worm is often referred to as Polychaete species 00.
  19. Sea Urchin Fossil?

    Hello there all! I have not been able to do much fossiling over the last few months as I have been busy with this and that, however in the last week I was able to take a couple of trips up to Mathesons Bay. The bay is situated in Leigh, north of Auckland and belongs to the Cape Rodney formation. The fossil bearing rocks in the bay are early Miocene, between 22 and 20 million years old (Otaian in New Zealand's geological scale). The specimen I'm wondering about was found in coarse sandstone, along with some quite nice little brachiopods ( in fact there is a piece of brachiopod attached to it). It is only a fragment but the piece has rows of knobs ranging from 2mm to 0.5mm in diameter running along its curved surface. There does not seem to be a clear pattern in regards the size of the knobs in each row, which leaves me wondering if it is a echinoid or not. However, it is possible the the variability in the knob's size is down to weathering, as the specimen is quite worn.. As far as I have read, the only echinoid known from the locality is Phyllacanthus titan, with that known from its fossilised spines alone (a few fragments of which I found, one quite near the specimen in question). I am wondering if this piece is from Phyllacanthus titan, or some other type of sea urchin. Thanks a lot! Here are a couple more pictures, the specimen is rather worn and a little difficult to make out I am afraid..
  20. A trip to Haute Normandie cretaceous cliffs ( The plasterers' balad ) - Part 1 During three days we travelled along the Haute Normandie coast. The area we ventured in is cretaceous : cenomanian (-99 MA), turonian (-93 MA) and coniacian (-89 MA), following the west to east dip. Day 1 : Antifer We met in Saint-Jouin de Bruneval, on the beach parking lot next to the oil terminal. We started the trip at 9 am, so we could hike quite far before the tide would stop us. Sky was shiny and quite fast the temperature started to rise. We mostly spent the morning looking for fossils in cenomanian boulders and chalcedonies among the peebles. We let the tide lock us and made a break for a picnic and a nap. Once the tide let us, we started again to look for fossils, under a scorching heat. At about 6 pm we made our way back to the cars. The beach which was empty in the morning was now overcrowded. We mostly found some irregular echinoids : crassiholaster and catopygus (some with a really nice preservation), some brachiopods, some bivalves (most fragile) (including nice rastellum) and 2 shark teeth. Here's a geoligical presentation of the area (in french unfortunately) http://craies.crihan.fr/?page_id=13478 Some of my finds on that day : heres a link a my flickr galery for the whole trip : https://www.flickr.com/photos/48637020@N06/albums/72157682540354264 Crassiholaster subglobosus Crassiholaster subglobosus Crassiholaster subglobosus with a smal bivalve print Catopygus colombarius more to come soon...
  21. Echinoid coral ?

    Hi folks, 1 item here for ID. It is a beautiful half bagel shape with the surface made up of polygons. A portion of a smaller one to the side. I searched it a bit and determined Echinoid coral, but found no illustrations resembling this one. I wetted it slightly for the pic to enhance the details. Please verify. Thanks.
  22. What is this fossilized in?

    I found these fossils on the beach in western FL, and although I identified these as echinoids (I do not know the specific name as I am a newbie fossil collector), I do not know what they are fossilized in. It might be coral? I have absolutely no idea, but all of you smart paleontologists have probably seen this before and can tell me what it is and if it's rare or not. Thanks guys! I tried with the pictures but my camera isn't so great. Also please excuse my non scientific language, I am not an expert like all of you, but I'm learning! Here are more photos Excuse the shells
  23. Goniophorus?

    I found this a few days ago in the Grayson Marl Formation. It looks like a Goniophorus to me.
  24. Apex?Que?

    When three guys with that kind of reputation in echinodermology get together to write a paper,you just KNOW it's going to be good. Highly recommended,particularly if you love your Loven,Mortensen,Raff,etc. Extremely well illustrated,IMHO Saucepourtpical 04 me.pdf
  25. Took a trip last Friday to a quarry that has exposures of the Eocene Castle Hayne Formation and the Cretaceous PeeDee Formation. First let me say it was hot!!! Did I say it was hot? During the day many of us spent extra time in the cars/trucks with the a/c running and drinking extra fluids. The forecast temps were for the high 80's and low 90's, but down in the bowl of the quarry with no wind I believe it was in the high 90's low 100's. However the finds were very good. Almost everyone found at least one Hardouinia kellumi echinoid, several nice enchodus teeth were also found. I saw several crab carapaces along with abundant H. mortonis and Echinolampas appendiculatta echinoids. A massive C. auriculatus was found that in my opinion if the tip was there (feeding damage) would have been close to 4 3/8 inches. Lots of smaller Eocene teeth were found along with some Squalicorax. A multitude of brachiopods were found also, a few different species too. As far as myself I found plenty of brachiopods, Plictoria wilmingtonensis and 2 other species I am working on I.D.ing. Plenty of H. mortonis and E. appendiculatta. I also found one H. kellumi and a very uncommon high domed H. mortonis emmonsi echinoid. Also a beautiful, but small enchodus ferox tooth; a nice small Eocarpilius carolinensis crab carapace and a very nice Entemnotrochus nixus gastropod (slit shell). A few decent teeth and a smattering of other items. H. mortonis on a natural pedestal H. kellumi H. mortonis emmonsi in this last pic the emmonsi is on the left to show the difference in the dome Eocarpilius carolinensis Enchodus ferox tooth Entemnotrochus nixus gastropod and the best of the many H. mortonis
