  1. Echinoids

    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.
  2. Maastrichtian fieldtrip in Belgium

    Today @Natalie81 and I went on a field trip with our geology club to the quarry of Eben-Emael In Belgium. We were over 50 participants today an I had the oportunity to meet aan other TFF member @ziggycardon This location is not far from the stratotype in Maastricht in the Netherlands and a multitude of fossils can be found in the marls and chalks. We had a slow start, but after searching through scree piles I found a small and a big sea urchin, and later on a few belemnites. Natalie hadn't got much luck at the start of the prospection, but she did eventually find the find of the day: a fragment of a turtle shell ( Allopleuron hofmanni ) with a few verts in association. We did have a great day and Ziggycardon had also his bag full of fossils and a great first fossil fieldtrip. the quarry: Maastrichtian marl ( formation of Emael ) Ziggy in action Natalie's turtle fragment: Home with the finds: A quick cleanup of the big sea urchin: Hemipneustes stratoradiatus
  3. Finally getting round to identifying some finds from over the years at different sections of Big Brook, NJ. I'm going to try and post them in separate topics. The white sea urchin spine is distinctive, but what are these other things? They have similar dots in lines, but the lines are much more spread apart. See that they have pointed ends and one has a wider end. They are about 2-4mm in diameter. Also, any idea or pointers as to what species the Sea Urchin spine could be? I haven't found an easy identification guide on the web yet.
  4. Hey folks maybe you can help me out. Especially the European collectors. Here in Texas we have historically had several species of Tetragramma listed as occurring in the Fredericksburg Group (Albian) that are possibly synonymous. For those of us who collect here in Central Texas there never seemed to be any doubts about what was a Tetragramma malbosii versus a T. taffi. T. taffi are always larger and seem quite distinct from T. malbosii. (see my two examples) But in 2016 William Morgan wrote the Collector's Guide to Texas Cretaceous Echinoids (Schiffer Publ.) and in it he lists T. malbosii as having precedence, suggesting that they are just not as full grown as taffi. He sites the work of Smith & Wright, 1993. I know T. malbosii is found in Europe. What about T. taffi? What does a very large European T. malbosii look like? The one I am using as an example is the largest one I have but it is still not as large as the T. taffi and doesn't have nearly the same number of tubercles in the interamb. Your thoughts, opinions, observations, etc.??? And if anyone can point me to a link or a PDF of the following paper I would greatly appreciate it and could reward with a nice Texas echionoid... British Cretaceous echinoids. Part 3, Stirodonta 2 (Hemicidaroida, Arbacioida and Phymosomatoida, part 1) Author: Andrew B Smith; C W Wright; Palaeontographical Society (Great Britain) Publisher: London : Palaeontographical Society, [1993] Series: Monograph of the Palaeontographical Society, v. 146, no. 593.

  5. Hey TFF Members! Cris and I were able to get out and do some super fun Echinoid hunting earlier this week! We were able to find some very nice specimens from the Eocene. If anyone has an ID on the big thick one I found in the video, please let me know! We got stuck in some nasty storms on this trip, but were also lucky enough to see a stunning rainbow! It was a great trip. Check out the vid if you get a chance!
  6. In the continuing saga of finding all the echinoids of Texas.....I found a few new things plus re-assessing my collection I found I already had another example (albeit small bits only) of another! So here are my latest finds (and re-finds). In my collection from Marathon Tx was a couple of bits of (I think) an Archeocidarid!! Stopped by a little creek in Austin and found this lovely Coenholectypus: Went on a little road trip to Glen Rose TX and found what I thought was a Loriolia but on closer inspection, it's a Goniopygus! Not a great specimen, but slightly better than my previous ones, so still looking for a nice one: And the piece de resistance : A Balanocidarid Spine!! Practically in my own backyard (well, within 30 minutes drive anyways)
  7. Hey have others been having trouble with the British Museum's online Echinoid Directory? It has been off and on for the last week or two and currently I can not get the Keys, Index to Taxa or Glossry to open. Hoping some of our friends across the water might have a little insight. https://www.nhm.ac.uk/our-science/data/echinoid-directory/

  9. So, I am formally stating my quest to find all of the echinoids (of Texas at least...let's not be silly) I live in Central Texas and we are blessed with an abundance of fossils. My first fossiking was in Cherry Creek, behind my house, in Austin. Although I did not really do much since those early days, now it has become my main hobby. I have collected a pretty dang nice collection of all kinds of Cretaceous creatures but echinoids are my favorite with ammonites a close second. I have decided to make it my goal to find all the species of Texas Echies I can find in my lifetime. So far I have hundreds of heart urchins, (Hemiaster, Pliotaxaster, Macraster and Heteraster), a fair number of Loriolas and Salenias, a couple of Coenholectypus and Phymostomas and one very very worn Tetragramma. I have been making forays to Canyon Lake to find some of the more "unusual" urchins. These are my finds of the last couple of weeks. They are not great specimens but I am totally excited about them anyways. Hopefully I will eventually find some better quality ones, but hey, gotta start somewhere. For an avid amateur like myself (who is still trying to figure out how to recognize formations and zones and not having much luck at it) its exciting to stumble across something a bit different. Goniopygus and Pygopyrinas

  11. Our Moroccan trip from 19th-23rd February 2019. Day One; Locality One IFRANE Here we are near Ifrane, a village built by the French in the 1930's in a Swiss chalet style so there are pointy roofs instead of the usual traditional flat roofs of Moroccan buildings. This is wifey and Anouar, a Moroccan tour guide, old friend and one time student of English, his brother, our driver Abdullah, is taking the photo. Anouar paid for the trip, accommodation and food in return for me teaching him a little about the fossils, crystals and minerals that we encountered. The trip was mainly an exploratory voyage for me to discover where was worth revisiting when i was alone and had more time to spare. Somewhere in this area are outcrops of Pleinsbachian (stage of the Liassic/ Lower Jurassic) rocks that are stuffed with terebratulid brachiopods including more than a dozen species and subspecies that were first described from this locality, many unique to the site. Unfortunately, it's well off the beaten track, but I think i know roughly where now, so will return another day. Not time today! The area is covered in loose rocks, ploughed up in fields and roadbuilding, eroded from outliers or washed into the area in the autumn rainy season floods or spring melts. The ones behind us look Middle Jurassic to me, yellowish limestones, some with iron staining. Upper Jurassic and Cretaceous rocks are also in the region. The high ridges in the background are basalt intrusions as the Atlas mountains were formed as Africa began to collide with Europe throughout the Palaoegene and Neogene and this resulted in a lot of volcanoes. We moved on north of the village and stopped where we saw a group of the local fossil huts. These are all year round businesses, but in the season, from May til October you will find little stalls selling local fossils and minerals all the way along the route through the Atlas Mountains to the Sahara. But the temporary stalls are all closed at this time of year, as it's pretty chilly and there are few tourists. Top Tip : Always pop into a couple of different shops and check out prices. Tell the next shopkeeper how much the previous one had stated and see if they'll undercut for a similar item. Always, always haggle! Top Tip : Ask which fossils and crystals are local if you don't know already; most of the shops in Morocco have local fossils and others from all over the country. Local fossils will usually be much cheaper, wait until you get nearer to the localities of other fossils and see the prices come down! Top Tip : If you have the time, ask the purveyors of local fossils to show you where they came from. Then go and have a look. They don't mind this at all.
  12. Odd Texas oyster

    I'll post a full story in trips when I get time, but I was searching around a new spot, being unsure of the formation (Austin I assume now) I was picking up everything I found including oysters which I would normally leave, I assume they're exogyra or ilymatogyra but the Mark on the back is strange to me, 2 of the three I picked up had them and I haven't seen anything like it in pictures. Species and out formation ID would be nice
  13. Does anyone have a recommendation for an identification book that would cover Florida Fossil Echinoids? I don't need a scientific paper, just good photos and content that focusses on echinoids, not invertebrates overall since the shells would take up most of the content.
  14. Figured we'd brave the cold today for a chance at some echinoids, first the leptosalenia texana.
  15. Dear TFF friends, I have those unclenead Mecaster lusitanicus (Loriol, 1888) from a XIX century classic location available for trade. I woul like humble european Pliocene Bivalvia for those or another echinoid specimen. Thank you! Mecaster lusitanicus (Loriol, 1888) C level, Cenomanian, Cretaceous. Salmanha quarry, Figueira da Foz. Regards, Ricardo
  16. sorry again, i dont know what the species of these specimens are and also sorry for some reason parts of the photos were cropped and made smaller i think its because i put too much on there so they had to cut down the file size (:
  17. My first trip out alone

    Got a chance to get off of work early so I hit a new creek I wanted to check out. I'm glad I did. I was only out for maybe 2 hours. These are my first ammonite and echinoid finds and now I want more!! I'm not use to creek hunting as I'm use to road cuts and mountain terrain
  18. Hello all you folks from NC. My mom-in-law gave me a pile of fossils from Ocean Isle Beach that she has collected over the years. Do any of y'all know the age of the stuff that washes up on this beach? Thanks jp
  19. Mysterious stripes on Echies

    I've always wondered what the 5 radial stripes on echinoids we're and what they do. Any urchin/sand dollar experts know? Polished Echie with the "stripes".

  21. Australian Echinoid ID

    Hello everyone! I have recently been going through my fossils from Mannum, South Australia and have been trying to ID them down to species. There is a couple echinoids that I have been a bit stumped by. I have ID them all down to genus but am having some trouble getting them down to species. What does everyone think? Here they are with a reference pdf: Any help is appreciated Thanks, Dan 1.(Photos 1-2) Eupatagus murrayensis? 2.(Photos 3-4) Eupatagus rotundus? 3. (Photos 5-7)Ortholophus morganensis?

  22. Fossicking with Frau

    I got my wife out with me today for the first time in a few months. Decent pickings in the Walnut Formation. Engonoceras ammonites in this formation are usually pretty fragmented. This one still needs 5 minutes of scribe work, but it’s a keeper. Can’t hate on those sutures.
  23. The Ocala Limestone Formation is a relatively pure carbonate (90% to 95%) limestone that was deposited in a shallow, marine environment. The thickness of the unit in Florida’s central peninsula is typically less than 90 feet. The age of the Ocala Limestone is late Eocene or about 35 million years old. This geologic age is based on correlation using macro-invertebrates and microfossils with well-dated rocks of the middle and western Gulf Coastal Plain. In the Haile Quarries, exposed in section, is a portion of the upper Ocala Limestone, formerly named the Crystal River Formation. I joined a field trip from 9am to 2pm Saturday into this Eocene era Haile Quarry. @MikeR also represented TFF. I had been to Haile Quarry previously in October, 2015. Some sights from the quarry on this 2018 trip. The Quarry is a BIG hole, high walls, lakes in the bottom, with piles of gravel, sand, clay, and limestone scattered around. Just walk around doing surface hunting. It is just too brutally hot to dig or climb. I walked this path next to the water, thinking that the extra moisture and muddy areas might expose some fossils. It was pretty clear that I had competition. But I figured he/she would only get the small echinoids. The best chances are for Echinoids, seashells, crabs, coral, and maybe sponges. There are also a lot of shell endocasts. This was a little strange. I was not finding a lot of fossils, but almost immediately after taking this photo of the butterfly, I spotted this Shark tooth fragment with colors out of sync with its surroundings. @Harry Pristishas made an excellent case for an Eocene era extinct Mackerel Shark. http://www.thefossilforum.com/index.php?/topic/84574-florida-eocene-shark/&tab=comments#comment-906155 I could not be more pleased than to have found a Florida Eocene shark tooth. Then a number of other finds, shells Endocasts, Something that looks like a sponge, Echinoids, It is likely that the 1st is Eupatagus antillarum and the second may be Oligipygus phelani. I really enjoy these field trips with good people and the real possibility of a surprise (like a Mackerel Shark tooth) while looking for Echinoids.
  24. I went to my fav cretaceous beach today ,great sunny day
  25. Echinoid

    last night there were heavy thunderstorms in Myrtle beach so I figured some good stuff would get churned up and deposited on the beach, I braved the brutal wind and cold early this morning and it payed off, I found these 2 fossilized echinoids within 20 yards of each other, any more specific info would be great!the top of the first is missing, and I know the second one is in real bad shape and a positive ID is unlikely.
