  1. Hi, Can someone please help me with an ID on the following fossils and how old they may be? Whale tooth (Florida) 80mm long x 25mm wide Sand Dollar (Morocco) 80mm diameter Thanks!

    Large sand dollar

    Hello I was wondering if anyone knew the species of this sand dollar. It's quite large 7.26x6.98" . I can't seem to find a match online that is this size and wanted to be certain they species so I can put on display correctly. It was found in North Port Florida from a lake that was being dug and because it being 20' below and finding Megalodon teeth around it I'm guessing it's from the Miocene to Pliocene Epoch. Any info or links would be most appreciated Brandon

    Circles on Sand Dollar

    I’ve had this mepygurus marmonti sand dollar from the Jurassic of Madagascar for years now and when I was looking at it I noticed these small circles on the bottom. Are these on every sand dollar, it appears to be a part of it so my guess was some sort of way for tiny legs to attach but it’s just a guess the sand dollar is 7.5 centimeters and each dot is just under 1 millimeter
  4. Hi, First time on this site and in need of advise. A BF & I found this sand dollar fossil at Stinson Beach a couple years ago. I want to make an effort to ensure I’m storing it right. I’m also curious how to clean at least the sand off, but maybe separating the large broken chunk from the (fingers crossed) undamaged sand dollar attached. Would that be detrimental to the fossil? thank you for all time & help, I can confidently say I know nothing. X Jake
  5. Hello members of TFF I'm looking for echinoids (sea urchins/sand dollars) to increase my collection of this kind of fossils. I'm interested in all kind of echinoids but what matter for me its the state of conservation. I have for trade several types of fossils from miocene (shark teeth, bivalves, gastropods...), cretaceous (echinoids, bivalves, gastropods) and Jurassic (echinoids, brachiopods, vertebrate material...) Thanks Vieira

    Is this a type of sand dollar

    What are these? Seems to fat to be a sand dollar. came from Greene county Alabama

    Mellita caroliniana

    Pieces of these are very common at this site, however complete specimens are very rare to find. This is the 3rd and by far the best specimen I have found at this site.

    Cool road find

    While working on a gravel road I found this beside my truck. I thought it was a piece of broken pottery at first.

    Encope tamiamiensis

    The sample image here was collected directly from a Drag Line operator's windrow in a lime rock mine in Southern FL just outside of Naples around the Sable Palm area of the Big Cypress swamp of the Everglades in 1997. The specimen has been completely removed from the limestone petrol (lime rock low density ls) matrix. What is interesting is the general shape of the specimen and how this 5 million year old specimen differs from the present day specimen at the same general location. I am guessing the seas of which the archaic specimens existed in were more challenging to exist in general as the specimen appears more elongate than present day specimen possibly for navigational purpose in higher energy seas than say today. Consequently the respiratory flower on top seems to be larger than today's comparable specimen as a direct consequence in the different morphology.

    What is this fossil?

    Hello, I was shell hunting today on Holden Beach and found, what I believe, is a fossil. It appears to be some type of sea biscuit(based on photos I’ve found online). It is very hard and filled with some type of compacted sediment. Any ideas what it might be and how old it is?

    Sand dollar prep

    Today I decided to try and prep a Sand dollar that was found by @digit and given to me at our March hunt at Cookie Cutter Creek. There was a good amount of matrix covering the top and bottom of this echinoid. While my main focus was uncovering the top portion I decided to also work on the bottom as well. Unfortunately I deleted the before pic by accident, but I took a pic that shows the pile of debris that I have removed so far. This is a work in progress so I will post more pics as I continue to work on it. First pic shows the top 2nd pic shows the bottom. As you can see from the pic all I have used so far is a pin vise and dental pic.

    Sand Dollar id please

    I'm interested in bidding for these sand dollars on our favorite website, but the seller can't tell me where they are from or what the statigraphy is. There are quite a few of them available on various websites, but they hardly give any more information about them. Most of them appear to be from Morocco, although I also saw similar ones from Florida. The given stratigraphy ranges from Cretaceous to Pleistocene and no one names even a genus, let alone a species. I sure would appreciate some details about them if anyone here in the forum has some in-depth information about them.
  13. Well, it's been a while since I've been out and about growing my collection of long-since-perished critters, so needless to say, I've been restless. I've been somewhat late in putting up my trip report, as this was doubling as a school project (writing a news feature on PAG (Paleontology Association of GA) for the school news site, 3ten) and everything at the place was taken on an NVidia whereas usually my smartphone does the trick. Anyway, enough BORING excuse backstories! Let's get to the meat of it! This past week was rather hectic for me. A trip to Pensacola where I swam in September ocean thinking it was July, a wisdom tooth surgery happened and the Braves got that sweet, succulent NL East crown, punching their ticket into October ball. Adding this trip on top of that made my fall break jam packed. I'd been waiting for an eternity to go to Sandersville with PAG ever since I heard of the announcement on their page way back in August. As soon as I was greenlit by my the editors of the school news to cover the event for school news, I was going, half dead from wisdom teeth or not. It turns out I wasn't as energy-sapped as I thought I'd be, as my wisdom tooth recovery had been pretty speedy (thank the Lord). Everyone going met in a Walmart parking lot more minutes away. We got told of the treasures we'd find (though I already knew): Periarchus sand dollars (heck yeah!) Crassostrea Gigantissima oysters (yes pls!) And shark teeth/Ray plates (good for me!) After that and a brief discussion on directions and my covering the trip for the school news, we headed off about a minute or so down the road to the landowner's property. We pulled in on a dirt road, and parked in an area of tall grass. The actual site itself was a short trek through the woods to get to the small creek where the Sandersville Limestone was actually exposed. It was somewhat difficult to get the camera equipment down to the creek along with the gear which I was actually using to get stuff out of the matrix, but it wasn't unmanageable and was definitely worth it. Here's what the much of the creek looked like: After getting together all of my pictures for the news, I went ahead and got to the fun part: finding stuff! My first and primary objective was the Periarchus quinquefarius kewi sand dollars, as with my trip to Montgomery in July, I have officially caught the echie bug. It didn't take very long to start finding them protruding from the limestone: After taking four with me, I moved to my next target: the Crassostrea Gigantissima oysters. These hold a special place in my heart, as my uncle Frank and I went driving near Griffins Landing trying to find an access point to get some of these huge oysters to no avail. Also, I heard that these oysters can only be found in Georgia (though i'm not sure about how true that statement is. Any answers regarding this?). To find them, I went a way downstream to where this Oyster exposure is: I was already getting packed with inverts, and I had a lot of stuff to carry back to the car, so I only took the most complete one I saw. Last but not least, I made a pitstop at where most of the group was sifting at a particularly deep and clay-ey part of the creek for shark's teeth and decided to indulge myself in a handful. Here are some of the other guys getting sift-fulls: Next post: My finds of the trip

    Periarchus lyelli

    Collected at the Martin Marietta Castle Hayne Quarry. This is a very common find, though most are limestone or marl encrusted or broken. P. lyelli is found in Zullo & Harris, 1987 sequence 4 of the Castle Hayne (Kier, 1980 middle to late biozone). A very similar species; Periarchus sp. is found in Sequence 3. P. lyelli is most easily identified and differentiated from Protoscutella and Periarchus sp. by the placement of the periproct. The periproct is located slightly above the central point between the peristome and the posterior margin of the test.

    Periarchus sp.

    Periarchus sp. is found in Zullo & Harris (1987) sequence 3 of the Castle Hayne Formation ( Kier, (1980) middle biozone). It is differentiated from Periarchus lyelli only by the placement of the periproct. In P. sp the periproct is below the midpoint between the peristome and the posterior margin of the test. On P. lyelli it is slightly above. Kier (1980), identified this sand dollar as Protoscutella plana; however Osborne, Mooi and Ciampaglio (2013) determined the oral plate structure separate these specimens from Protescutella plana and belonged in the Genus Periarchus.

    Fossil Sand Dollar.JPG

    From the album: MY FOSSIL Collection - Dpaul7

    Fossil Sand Dollar Baha, Mexico Miocene (3.6-23 Million years ago) The term sand dollar (also known as a sea cookie or snapper biscuit in New Zealand, or pansy shell in South Africa) refers to species of extremely flattened, burrowing sea urchins belonging to the order Clypeasteroida. Some species within the order, not quite as flat, are known as sea biscuits. Related animals include other sea urchins, sea cucumbers, and starfish. Sand dollars, like all members of the order Clypeasteroida, possess a rigid skeleton known as a test. The test consists of calcium carbonate plates arranged in a fivefold radial pattern. The ancestors of sand dollars diverged from the other irregular echinoids, namely the cassiduloids, during the early Jurassic, with the first true sand dollar genus, Togocyamus, arising during the Paleocene. Soon after Togocyamus, more modern-looking groups emerged during the Eocene. Kingdom: Animalia Phylum: Echinodermata Class: Echinoidea Order: Clypeasteroida
