Again, thank goodness for cameras and closeups!! I thougth this was a large orbitolina when I found it, but noticed that there was an odd pattern on the underside. I just figured it had some strange mishape. But then I was looking through @Uncle Siphuncle's Fossil collecting reports and ran across something that looked very similar - floating crinoid Peocilocrinus but they were from the Paw Paw formation in North Texas and this is from the lower Glen Rose in Central Texas. So I realized i needed to get a better picture and lo and behold....it has interesting pattern on the backside!! I remembered a picture I had seen of a starfish dermal plate or something that had these same striations on it. Can anyone help me ID? @erose or @JohnJ? Thanks for your time!! close up

Finally got some time to do some fossil hunting during my travels. This was as I was going through North Texas. Found some beautiful partial ammonites with sutures showing, and one (my favorite) ended up having three echinoids still in it. I plan on leaving them in there, of course. This guy was like 50 pounds Before cleaning with a brass brush After cleaning The whole view Too big to bring home. Maybe I'll grab it next time. I'm so sad I lost this little ammonite on the way back to the car See if you can find the echinoid I missed, but found afterwards while looking at this picture

Echinoid Salenia question and ID of tiny spiral - gastro or worm?
JamieLynn posted a topic in Fossil ID
Hello all! Went a hunting in the Glen Rose Formation yesterday and found a few nice salenia texanas...I think. The first one, has the rounded cap, the next one is a bit more "indented" But the last one has a very different looking "cap". Is it perhaps something else? Also found this tiny spiral, I am thinking its a worm, but never seen one do this perfect spiral. It's so tiny and poorly preserved, unfortunately, pictures are hard to get. Any help will be appreciated! -
While working on a gravel road I found this beside my truck. I thought it was a piece of broken pottery at first.

A recent acquisition that I bought just because it's beautiful. Impressions of cidarids crop up quite often in Cretaceous flint but I've never been lucky enough to find one (and I live in the wrong area). Probably Temnocidaris sp., Upper Cretaceous, Santonian, Kent coast, southern England. Test fragment 13mm across

The first week of June I managed to break away from a European excursion with my wife to do a couple hours of collecting in northern Switzerland! We found a boatload of late-Jurassic (Birmenstorf-Member) ammonites and one nice echinoid which should be awesome with some prep! Funny part, on the drive back my wife mentions finding an ammonite that looked like there were nipples on it. Not until we get back to the apartment and start cleaning things off do I discover it was the echinoid she was talking about! *shes a rookie I could use some help with ID confirmation and IDs in general. Taramelliceras callicerum Ochetoceras canaliculatum Paracidaris blumenbachii Trimarginites arolicus (easy because of the grooves on the keel) These have fine ribs, are super thick relative to size but have goniatite type 'sutures' thoughts? (I dont think the far right one is equivalent, i have some other pictures of that one) Assumedly all of these are Perisphinctes, but I cannot tell the difference between all of those ribbed ones to save my life. They may need some prep to help determine Fatter, round keel. Glochiceras? There are quite a few that look like Trimarginites but have smooth keels. Thoughts? Are they just more weathered potentially hiding the grooves on the keel? These, from the paper most closely resemble Glochiceras crenatum but I dont feel like that specimen is closely enough related. I would think those spines along the keep would be easy to ID. One more, its a bid weathered but I figured someone might recognize it. Has some decent sized spines along the edge of the keel (arrows) Euaspidoceras oegir, maybe? Thanks for any help!

I was at the chalk cliffs at Seaford in April this year hunting for echinoids. However, I only found time to clean and prep these fossils this week, using a safety pin, a brush and water (Very low-tech, I know!). UKfossils.co.uk states the rocks here are Cretaceous, 89-86 million years old. I found a fist-sized chunk of chalk that yielded two enchinoderm plates (picture 4) and a very small, unknown fossil. Pictures 1-3 show the unknown fossil. 1 division on the ruler is 1mm. It is perfectly spherical, with a diameter of about 4mm and has raised dimples covering its surface. There are at least two holes, but they are not opposite each other, and I am unsure if these are biological features or just preservational artifacts. My thoughts are this is either a bryozoan or a small echinoid, but I am not sure.

Hi, I found this crushed echinoid in an Upper Campanian/Lower Maastrichtian stage of the Pyrenees. "Not much of a piece", I tought (likely a Micropsis or a Phymosomatoid). But I wonder if this can be its crushed Aristotle's lantern: Close-up: The other side:

All the Echinoids (Of Texas) Part 3 Cretaceous Crinoid!
JamieLynn posted a topic in Fossil Hunting Trips
Wellll....a successful day today!!! On my continued quest to find all the echies I found something I never really expected to find- Cretaceous Crinoids! It's Isocrinus annulatus. Also found a crushed up Pygopyrina hancockensis, a nice big one. And one sea urchin spine. So a good day in my book! -
So yes, I went fossil hunting for the first time with two friends two days ago behind my friend’s grandma’s house in some farmland and we had a blast finding fossil shells of echinoids and gastropods and whatnot. Before we left though, my friend’s grandma gave us this really well preserved fossil of an echinoid (at least compared to our finds) and asked us if we could perhaps find out how old it is. I tried to do some research on the web but its an absolute maze but I stumbled across this forum. So im hoping that through identification, we’ll be able to find out about how old it is because i feel like its the least we could do for my friend’s grandma who entrusted us with this amazing fossils of hers. Anyways, imma get straight to it now. Its was found in some farm land which has some sedimentary rock underneath all the soil. The excavation of this rock to till the ground better has created quite a few piles of this rock here and there which also contain fossils of sea snail shells, some really round looking clams, and echinoids just like the one in the pictures. The rock surrounding the fossils are a really light orangey color and is really easy to chip at or scrape. Probably limestome but not sure cuz im still new to this. This is all located in the Philippines up in the mountains on the island of by the way. It’s 13.5 cm across what I believe is its “front end” to its “back end”, 11cm wide, and about 3 cm tall. Again im new to this so if there are any details that still need to be mentioned or if some additional pictures are needed, please ask because I would feel really bad if i didnt grant this sweet old lady her request. T^T Any info about how old it could possibly date would really mean alot but other info on it would be really great too ^-^

I am trying to identify the species of a number of incomplete but highly detailed Echinoid ' club' spines ( tubercles ) I have found in one , very small fossil ground in Ibiza ( Balearic Islands ). I want to post photos , but this is my first entry to the forum and, being a bit of a fossil myself I'm not as yet clear on how to do that ! I have been in contact with Andreas Aroh, Editor-in-Chief of the Geological-Paleontological department of the Natural History Museum of Vienna , but all he can tell me on the matter is that he doesn't think they are genus Pseudocidaris , but thinks he may have seen such spines in a paper ......but can't remember when . somebody please explain how I may attach the photos of these spines !

So I am looking for this particular urchin. My grandmother found one when she was a child on the Brazos River outside of Waco TX. Her father sold it to a family friend in the late 1930's and so all I got were the stories of this big round rock that she thought had been "carved by Indians, decorated with dots and snakes". Only much later did she find out that it was a fossilized sea urchin. I am guessing it was a Cidarid, possibly Phyllacanthus or or Paracidaris. All I know is I am determined to find one someday. I would trade my entire collection of fossils for one of those big echies. (If anyone happens to have one just laying around.....let's talk! hahah) . I have been trying to learn the different formations and I stalk the Fossil Forum regularly to learn what I can. When I saw a post by @KimTexan about a Cidarid ID I realized she had found what I had been looking for! (Kim, I am so very jealous of your find!) So, my husband and I set out on one of our "little hunting trips" - we like to take two or three day excursions around Texas - he gets to go ghost hunting at night (we stay at haunted hotels and B&B's) and I get to go fossking during the day. I mapped out some likely spots and we set out from our little town of San Marcos heading north to HIllsboro (excellent home made icecream at A Tisket A Tasket on the Courthouse Square) and then to Granbury where we stayed at the Nutt House Hotel. Stopped at two spots that I thought likely to find my urchin but alas. No luck. Found some nice heart urchins and some "new to me" oysters and a couple of nice chucks of ammonites. I think this was Washita formation? I am using the Rockd App on my phone to try to pinpoint formation since I am definitely not familiar with formations, especially up "north". One of my happy finds was a Pinna Comancheana (far left "cone shaped" fossil) I've only found one other of those. Next morning we headed up to Lake Benbrook Spillway with a stopover at a large roadcut on "Scorpion Hill". This I believe was Glen Rose as most of the finds were heart urchins and gastros. Nothing new to me here, but I did find some better specimens than I had collected previously. Lake Benbrook was a neat place. Two other fossikers were out, I went over to say hello, wondering if they were experienced hunters and knew the area, but nope, they were new to Lake Benbrook, just as I was. I did not get to catch up with them after to see if they found anything good. I was amazed a the large ammonite impressions in the limestone beds. My camera wasn't working, so alas, no pictures. Found lots of nice Oxytopodiceras fragments and a couple of others I haven't identified yet. Pics in next post:

Echinoid Jackpot! 7 species! 3 need help ID'ing - Texas Cretaceous
JamieLynn posted a topic in Fossil ID
I found "A SPOT" finally!! Found 7 species of echinoids, and am over the moon! I am able to ID some but not all. Could use a little help please! Location: Comal County near Canyon Lake TX. Cretaceous Glen Rose. I'll post pics of the others i have tentatively ID'd in the comments post, I would appreciate confirmation on those too. Here are the ones I am not sure about: I thought these first ones were Coenholectypus, but they are very "off center". But they could just be squished. Is this Pseudodiadema perhaps? Perhaps too small and busted up a specimen to ID. Thanks for your help!! -

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.

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.
