    Crinoid Segments

    From the album: Delaware Fossils

    Oddly smooth, but typical of this locality, these crinoid segments are only about 2mm in diameter. From the Cretaceous spoils deposits of teh Chesapeake and Delaware Canal, Delaware.

  2. Any ideas what this is? Found in Maryland. Has kind of a hex pattern on one side.
  3. Over the winter holidays I took advantage of the time I had off from work to go on a nine-day fossil collecting road trip through Mississippi and Alabama. Last week, while collecting at an exposure of the Late Cretaceous (Maastrichtian) Prairie Bluff Chalk in Alabama, I stumbled upon a fragment of a cidarid echinoid with six associated plates. After some research that night from my hotel room did not provide an identification, I sent an email to George Phillips, the paleontology curator at the Mississippi Museum of Natural Science, asking for help. What I initially thought was just a cool find
  4. From the album: Texas Echinoids, ERose

    Update: Since I originally posted this image I now have fairly positive identifications for three of these and a good guess on the fourth. From top to bottom: The knurled large spine is Paracidaris? texanus (Whitney & Kellum) one of two known cidarids in the formation; The second is Pseudodiadema aguileria (Maldonado) and is recognized by its triangular cross section; The third is the unknown. It looks like spines on some Goniopygus but there are no large Goniopygus in this strata. It is more likely a scrobicular spine (https://www.nhm.ac.uk/our-science/data/echinoid-directory/taxa/glos

    Lake Texoma, round 2.

    Alright folks, just sit right back and you'll hear a tale, a tale of our fateful trip... but if your in a TLDR mood.... Fossils get real heavy, real fast, and we found a lot. I had a rare full weekend off work, so my son and I went back to hunt the lake Texoma shoreline for a 2 day exploration. We started off in the same beach we found last time (that I dubbed "Echinoid Beach"), but construction had changed everything and made it much harder to hunt. The worst part is that last time we left a small pile when moving everything back to the truck. I knew where it was, but when we a

    Video of Lake Texoma hunt

    Fossil Friday! Today's FF video post is from Lake Texoma. We made our first ever trip to lake Texoma to search the duck creek formation for ammonites. After much research and planning, we arrived to find we could not access the locations we wanted, so we ended up scouting around. It turned out well and we found some great fossils including ammonites, oysters, clams and echinoids.

    Texoma Duckcreek fm hunt

    Yesterday, my son and I finally made a day-trip to Lake Texoma for some fossil hunting. We've been wanting to make this trip for while, but it can be difficult between both our jobs and weather, and lake levels. I planned for this trip by searching the google maps for good looking locations with a nearby shore access. Unfortunately, one spot turned into a private drive, and the other was closed off by the Corps of Engineers for some unknown reason. We didnt want to hit the same spot that everyone else goes to so we began just driving and looking. The first place we stopped was

    Modern Caribbean echinoid

    I’m not sure if this is allowed as a one off post, but I’ve been trying to identify this Echinoid I found in Turks and Caicos and I can’t find a species name and I was wondering if anyone knew it, thanks it’s a beast
  10. Found this a few days ago in a local creek that has Woodbine. When I picked this up it had an "echinoid sheen" to it. Also thought it was just a possible bi valve. Not so sure after looking at Turtle egg fossil or rather possible turtle egg fossils on Google.
  11. Hello all! This is a little photo project I've been working on for a while. When I first started Fossil Hunting I was content to collect whatever. Then I was excited about Identifying what I was finding. The education continued and now I work to identify the geological formations I am collecting in and am able to know what fossils to look for in what areas. The Pocket Texas Geology website is invaluable for finding out the formation of a specific area (while not 100 percent accurate, it's pretty good). So I wanted to create a post that would help with Central Texas Cretaceous Fossil Identific

    Tetragamma Tease

    The last weekend of September, I decided to visit some of my central Texas sites. I had been looking for a tetragamma for some time - the first one I found was collected illegally, totally by mistake, on federal property. And it was far from a perfect specimen. Well, after a few years of being teased by broken tetragamma bits, I found this beauty. I believe this is a tetragamma streeuwitizi - collected from comanche peak limestone. Please forgive the situ pic, motion picture was activated, and the sun was too bright to tell that it was a poor quality image until later.

    A type of conoclypus?

    Hello, I picked this fossil up on Jebel Hafeet, Al Ain, UAE (United Arab Emirates). I think it's from the Cretaceous, however, I am not so sure. It is unfortunately very worn and eroded, but it is still the only one I have of its kind. The fossil itself it filled with small numulites. I saw a picture the other day of a conoclypus echinoid, and it looked quite similar to what I have. I figured you guys would be able to confirm whether it is or not. I also drew a picture of what I imagine it would look like whole.
  14. Hi, I was hoping that someone would be able to tell me if the smaller echinoid is a juvenile Corystus dysasteroides or possibly another species. Both specimens were collected from the Jan Juc marl, late oligocene (Janjukian), Victoria, Australia. Thanks. (I posted this in the wrong place earlier)

    Fossil echinoid

    Hi guys, I lost the label on this, I’m fairly sure it’s from the Pliocene of safi, morocco but I could be wrong, would anyone have any idea what it is? Thanks
  17. There is a spot in the Peace, not far upstream of the Canoe Outpost, that yields relatively large quantities of the sand dollar shown in the photo below. I have these 2 relatively good examples and 3 more partials stuck together in a block. All are of nearly identical size. I had assumed Miocene based on the source, but the the publication from UF on "Pliocene and Pleistocene Echinoids" has the only sand dollars coming close. The closest matching in shape is Encope michelini, but the sample is twice the size of my examples. Anyone have experience with these?

    Some echinoids :)

    Hi Guys, I don’t know if we have any echinoid experts on the forum but I figured I’d try, I’ll start with this piece this is miocene from the Murray river, australia, there is a lovenia woodi on there but I’m not sure what species the regular echinoid is, thanks for your help

    I have this Echinoid I think

    I found it on a south west cliff/beach and it has a odd internal spine like thing. Any ideas? I’m quite bad at IDs as well, so any clues about it ? Please help. Here’s some photos hope this helps. Thanks for your time. God fossils still fry my brain, just thinking how old, and it’s trip to get into my hand still makes me go woah! Last 2 phots show the spine like thing quite well
