This specimen comes from the 1980 dredge spoils of the C and D Canal. The type specimen for this species comes from the Navesink Formation exposure of the same canal, not far away. Known by locals, it was not actually described until 1986. Although not the most common of species at this locality, and almost unknown outside of Delaware, these miniscule urchins were nonetheless plentiful at the Reedy Point spoils. Recent excavation for barrow removed most of the sand where my specimen was found.

I put this on the microfossil forum as well, but wanted to give a look-see to this intriguing fossil! In my search for conodonts in Pennsylvanian stark shale (between Winterset and Bethany falls limestone) I routinely find concretions/nodules-most are powdery but sometimes i find teeth and other microfossils. Well much to my surprise, upon splitting my thousanth shale, I found a 1cm nodule, and within it, this apparent micro sea urchin-one of two in the nodule. From spine to spine (7:00-1:00) it measures just under 2mm in diameter I am refining my photog techniques with a

Hi there folks, I need help and advices on how to prep some echinoids that I have found on calcarenite matrix. I am new in fossil prep plus I know these kind of calcarenites are very sneaky to treat. In the picture below there is a Scutella subrotundae before and after a quick prep-test I did with a couple of nails. The problem now is to take away the sand grains very close to the shell. Which technique should I try to follow now? I am thinking to the digestion in cold acetic acid, which I know it is used to extract microfossils from limestones and calcarenites, but I do not know i

From the album: Delaware Fossils
So sweet! This is a very rare Cretaceous echinoid (sea urchin), Boletechinus. They are typically no more than a couple mm in diameter. This one is shown next to a pencil eraser. Most of the ones in the Smithsonian's collection come from sand and silt removed for the creation and maintenance of a canal, which exposed fossils well below the surface. This one comes from New Castle County, Delaware. -

A few specimens declared "Danekræ"
Phevo posted a topic in Partners in Paleontology - Member Contributions to Science
Thought I would share a few specimens that made it to the National collection in Denmark. Back in 2017 I found a Cyclaster sp. from a site in northern Jutland primarily known for it's commonly found Echinocorys sulcata. Out of around 150 primarily fragments found of Cyclaster sp. , roughly 5 were complete and only one fully inflated. Considering that they go through a rough process - First the material is excavated from the walls using a hydraulic excavator, then the material is spread out on the "floor" of the quarry and turned multiple times to reduce the- 7 replies

During a trip to Egypt I found this potential fossil near the city of Aswan between the banks of the Nile River and Sahara Desert. I had thought it might have been a meteor and the sand fused around the meteor due to the Intense heat. But, I tested it with a magnet but there was absolutely no attraction. Therefore, I thought it might be a fossil given that I read about many fossils being discovered in the Sahara and the composition does appear to be any rock or stone that I've ever encountered. I assumed crocodile due to the spiky and bumpy texture, along with the historic prevalence of crocod

Here are my new fossils! And how my collection looks now. For size comparison the enchodus tooth to the right in the picture of the entire collection is 5,6cm long (2.2 Inches long)

So-this collected yesterday in the Kansas City area again, but not sure what "layer" as the road cut was a jumble of mixed rock. My first thought was sea urchin spine, but I see only one row of spines, similar to what you see on many crustaceans; even though it is half-buried I thought sea urchin spines had generalized "points"?.... thanks again for all your patience reviewing these!

Found this after the huge rain a couple miles from the ocean in Cardiff California. There are sandstone hills nearby and I'm also trying to classify what may be a fish. Is it an urchin? Or a barrel cactus. Thanks in advance

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

Found small sea urchin next to the ammonite in Lake Texoma Duck creek formation over the weekend. While I was cleaning the sea urchin, I noticed something that caught my eyes. It appears to be a small worm that lived in Cretaceous sea, gotten attached to the sea urchin and fossilized at the same time. Anybody familiar with sea worms like this?

The first 8 are echinoids and echinoid spines, I have seen plenty of photos of them while researching forams. Doctor Mud.....I can not confirm it but I do think you may be right about the last two being some sort of echinoid, This thing is only about a half a millimeter in size, I can't find anything online that looks like it but will keep at it.

I took a trip to Big Brook in Monmouth County, NJ yesterday and found some things that I need help identifying. Any help would be appreciated! Pic #1: Possibly sea urchin spines?

This is another piece discovered at an estate sale, which of course means I do not have the info such as location it was found, etc. It has some amazing detail, spiny legs? but it's so squished into the matrix I have no idea what it could be. Hope to receive more info. The piece is approx. 6 x 4"

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?

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.

I and my 8 years old boy a great time fossil hunt in Texas. During our time in Austin, with Erose help, we hunt at Texas 360 and found a nice sea urchin, some devil toe snail (oyster,) and shells. It was raining so I didn't spend much time there. After Christmas, we start our fossil hunt trip. We stop at Meridian road cut for some heart sea urchin, coral, and shells. Then drove to Mineral Wells Fossil Park. My son love this place so much because the fossils are so easy to find and he love crinoids. We didn't find any shark teeth or trilobite but we are happy. My son want to

looking for fossil sea urchin spines from Texas.
DLB posted a topic in Member Fossil Trades Bulletin Board
I'm looking for as many as possible urchin spines all sizes to reconstruct an urchin. I would also like matrix to mount it on preferable from the same area as the spines. I can trade fossils from Washington a prepared crab or unprepared either of your choosing.
