Here is an echinoid I collected several years ago while sifting in Post Oak Creek in Sherman Texas. I haven't ever seen another one come from there. Anyone have an idea on the identity of it. The grid paper is in mm so this echinoid is approximately 10x10 millimeters in size.

During my organization and cleanup process in my never ending abyss of the fossil garage, I came across these gorgeous calcified fossils which are both cretaceous. I kind of misplaced them for a little while... I found them both at a sand pit in Coastal North Carolina a few years ago. So, show us your splendid, dandy and awesome calcified cretaceous fossils PLEASE! I shall start first on this cool lil' prospect to see what may be shared by other members.

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?

I've received papers recommended by forum members and I'm looking to identify or verify the ID's for a number of pieces still confusing me. In the Santa Fe river, while sifting limestone rubble, we find numerous examples of what previous posts on TFF identify as Rhyncholampas goldii (or the molds thereof) an Oligocene sea biscuit from the Suwannee Limestone. On much less frequent occasions we come across the molds of the sea urchin in the photo below. I'm having difficulty determining whether these are Gagaria mossomi or Phymotaxis mansfieldi. I'm leaning toward P mansfieldi, because the the regularity of the test. Can anyone help?

When I saw the beard on this echinoid, the name stuck. Duck Creek or Fort Worth fm, North Texas. I don’t find them often with such a luxuriant plumage of spines, so I’m reluctant to prep further for fear of knocking off the fuzz.

Either corals or echinoids are my best guess here. More of mom's stuff from Pelee Island, Canada.

These are a few other fossis I have found in the past .I have collected fossils here for nearly 40 years but most of them have been given away or donated to a local museum here in Birmingham . The sharks teeth are Cretaceous form the Mooresville chalk formation . The Echinoid was found at St.Stephens Quarry years ago in the Yazoo Clay . The little Trilobite came from a site near Russelville in the Tuscumbia Formation . I have found fossils all over , these are the ones that are most convenient to photograph at this time . The arrowhead was found in a creek while collecting fossils .

The apical plates are rather prominent (for a holectypoid) on this specimen...the only one of its kind I've run into. Test 9.3 mm diameter, 6 mm high.

I hadn't seen an echinoid with beekite before so I had to buy it. Micraster glyphus?, Campanian, Höver, Germany.

Dear all, I have many duplicates in my collection and I would like to exchange them with other fossils from around the world. I'm interested in any kind of fossils, (dinosaur) teeth in particular. #1 This should be a piece of echinoid. A gift from a friend, it may have been found in Italy. #2 Fossil wood slice (probably from USA). #3 and #4 Pectinids from Favignana, Sicilia, Italy. #5 Unknown piece of marine fossil from Sorrento (Amalfi Coast), Italy.

Lovenechinus lacazei (Julien) (most likely this species but I'm not sure if there's really enough diagnostic detail). Lower Carboniferous, probably Tournaisian. Very rare anyway but of especial interest as it is from the Jurassic Doulting Stone (Bajocian, Inferior Oolite) of Somerset, UK. This is a limestone full of Carboniferous detritus, formed when the Jurassic sea was washing up against the Mendip Hills Carboniferous high ground. (Just acquired via a dealer from an old collection that included Carboniferous coral and crinoid fragments from the same location. No other echinoids though!) 2.3cm across

Between honeydos this weekend, the Cenomanian Crevasse sang its siren’s song again, tickling my ears, and I was helpless to the call. I will take my buddies with me soon, but the 30 minutes spent solo on site this weekend were pure bliss. On gloves and kneepads I navigated the hummocky surface of the Mainstreet limestone, tapping the pregnant humps with my hand sledge, listening for hollow thuds, and flipping some easy splits. Neithea scallops and Waconella brachiopods were only outnumbered by Ilymayogyra oysters. But I was after a few things a bit less common. One fortuitous blind flip triggered a spontaneous “Tim the Tool Man” chortle as I spotted 2 big whorls of a Mariella ammonite, with perhaps a third diving into the rock. Prep will tell. But this was just a warmup.

This is part 2, site 2 of my Memorial day fossil hunting trip. You can see the site one report here: I chose to drive out to Denton Creek north of Ft. Worth. I had been there before, but had not gotten to explore the area. It was the takeout point from a kayaking trip I’d taken down the creek a few weeks before. It took me 30 minutes out to drive out there from the first location I hunted in Benbrook. If you pass the creek going north you can go up to the next exit and then loop back to the creek. There is a little rock and dirt path off the shoulder of the road that leads down to under the bridge where you can drive your vehicle. The hill down to under the bridge is kind of steep. My car was a bit on the low side for getting over the curb and then a steep embankment with rocks. I bottomed out once. I thought I might park my car in the shade under the bridge, but when I arrived there was another vehicle in the area. I thought I was the only person crazy enough to be out here in the heat. Nobody could pass if I parked under the bridge so I pulled through into a small clearing there. The grass and weeds were grown up pretty high in the clearing. I knew of a sizeable exposure on the creek that I wanted to try to get to on foot, but I didn’t know the terrain around the creek. I switched to my rubber boots for walking in the creek. I reapplied sunscreen and headed down the steep hill to the edge of the creek. I had to sit down and scoot myself over the edge and drop down to the rock ledge that ran along the creek. I inspected the exposure. Last time I was here I found a pretty decent Macraster obesus right by the spot I came in by. I didn’t see a single fossil. The creek was maybe 40 feet wide give or take. The water was less than 10 inches deep where I entered the creek. I don’t think the creek is ever a high energy creek. The rocks that are in this part of the creek are angular and jagged. The water in the creek is rather murky so you can’t see into the water. All of that makes it a difficult creek to walk in. Most of the creek in that spot is one level at bedrock with rocks scattered across much of the creek bottom. There is a narrow jagged rift in the bedrock that meanders along the creek bed. The water is deeper in the rift. I walked down into the creek and squatted down looking at some ammonite fragments in the creek. I saw two butterflies nearby. I tried to get a better picture from the side, but they flew away before I could do so. Sorry it is not a very clear picture. You can see the creek bed is kind of slimy looking. In some areas where the water was very low it looked foul and fetid. It had a green bubbly looking surface. I assessed the creek and decided to walked along the exposed rock ledge above the creek. As I walked up the creek there was a horrible stench of something dead. The further I went the worse it got. Finally I came upon a gar fish carcass on the rock ledge above the creek. It was close to one of the places where I had wanted to have a look around, but the odor was too strong and repulsive. It looked to be just over 3 feet long. I can’t imagine how it got there. It had to be a person who had drug it there. This section of the creek does not seem deep enough for such a large fish to swim in. Maybe it swam in the rift though. There were deeper sections of the creek where it could live, but not here. There were signs of racoons all over along with remnants of their meals. Evidently gar is not on the racoon menu, which was surprising to me since it seems raccoons will eat almost anything else. I looked at the thin, razor sharp gar teeth. It is kind of scary to think that type of critter was in this creek when I kayaked it. I was in and out of the water all the time. A bite from that thing would be nasty. Here is a pic of it. I walked back down the creek upon the rock ledge to a place where there weren’t too many jagged rocks in the creek and where the rift in the creek would be narrow enough for me to step across it. Since the water was flowing slowly the rocks were covered with algae and were very slippery. I got to the rift. There were rocks pilled up there. I place one foot on a large one sitting at an angle and it tottered underneath me. I made sure my foot wouldn’t slip and I balanced myself as I put my next foot on another rock. It tottered too. To slip and fall in this creek with all the jagged rocks would really hurt and might do considerable injury. At least when I slipped and fell in the NSR the riverbed was smooth, without any rocks. I took a few more steps on similar rocks and I was I on smooth riverbed again near the other bank. I began to inspect the exposure. I found these just sitting on the bank. A cute little impression of an ammonite and what appeared to be a fragment of a Pinna clam. I have yet to find a whole Pinna clam. I’d kind of like to find at least one whole one someday. The only other formation I have found them is in the Goodland. It is another of the Washita Group formations.

During april i and a friend had the oportunity to spend a few days hunting in cretaceous of Normandy, hunting for echinoids. Day one : We drove from brittany through Le Havre to Saint Jouin de Bruneval and Antifer Cape. (3 hours and a half) We let the car on the beach parking lot and hiked south on the peeble shore looking for fossils in the boulders on the beach. The cliff is cenomanian with a bit of albian at the bottom. You have to look carefully on rocks surface for the familliar spherical shape. I found about 20 urchins but thats about it. No shark tooth, just a poorly preserved ammonite (mantelliceras) and a few rhynchonellas At some point we noticed tide was coming back faster than expected, most likely because of the wind pushing the water back. We had to quicken the pace, and made our way through the slippery covered with algae rocks. We finally managed our way back to the car and took the road to Fécamp where we had booked an hotel for the next 2 nights. some finds of the day : Crassiholaster subglobosus : Crassiholaster subglobosus : Cyclothyris difformis : See the all hunt gallery here http://www.thefossilforum.com/index.php?/gallery/album/2849-haute-normandie-april-2018/ or on my flickr : https://flic.kr/s/aHsmiwWft6
