  1. I was knocked out (figuratively) by this little nodule as soon as its finder and preparator posted it. It now sits prominently in my belemnite display cupboard. Belemnites are my main interest which is the official reason I wanted it, but for some specimens it's just love at first sight. It's a Nannobelus acutus (I think - it's not always straightforwards...). They're scarce in this subzone locally, and only very rarely crop up in classic Sinemurian ammonite nodules from Dorset. In fact, I know of only one other but I'm sure there are more out there. (At other levels, and elsewhere, it's a common belemnite.) The ammonites are mostly Cymbites sp. (little, sub-spherical things), with one Asteroceras cf. margaritoides visible (there's another hiding under the belemnite). I think it took vision to decide to prep this - cracked open, you'd just see common little ammonites and a broken belemnite which a lot of people might not bother with, but it's turned into one of the most aesthetic specimens in my collection. Lower Jurassic, Black Ven Mudstone Member. Obtusum Zone, Stellare Subzone, Charmouth, Dorset, UK Nannobelus: 4.5cm Asteroceras: 1.8cm Cymbites: 1cm down to 2mm - I love the hollowed apertures!
  2. Crinoid columnals ?

    I found yesterday this -I guess- pieces of crinoid columnals in a Lias (Hettangian) strata. In my area -Pedraforca zone, SE of Pyrenees- Jurassic sites and crinoids are rare (most sites are Upper Cretaceous), so I know very little about them. Tne only crinoid mentioned for the area and period is Pentacrinites. Can you confirm/refute my guess? Thanks.
  3. Dear TFF members, I have bought a lot of fossils from Buttenheim, Germany, Lias epsilon. The seller said that there are bones and teeth, but there were no labels attached, so I need to ID them The first one comprises belemnites and? Brachiopods? Belemnite is 8 cm, potential brachiopods - 2, 3 cm in diameter. Then a piece with a paddle bone of Ichtiozaur? Potential paddle bone 1x1.5 cm. A bivalve? 1 cm A single vert - could be of Ichtiozaur? 6cm in diameter Then several pieces with teeth - of what? The smallest one is 0.5 cm, the biggest - 1.3 cm. Two pieces with bones? 3.5 cm and 4 .5 cm.
  4. Microderoceras sp. (Hyatt 1871)

    From the album Cephalopods Worldwide

    25cm. Early Sinemurian, Early Jurassic (Lias). Provenance unknown.
  5. Ichthyosaur stomach contents

    From the album Marine reptiles and mammals

    Cross sections of the stomach, full of squid/cephalopod hooks and beaks, of an early Jurassic ichthyosaur (Stenopterygius quadriscissus). One slice has the animals ribs, the lighter tan objects, around the stomach, while the other is entirely of the stomach contents.
  6. At over 4" across, this is the last few chambers of by far the largest diameter belemnite phragmocone I've ever seen. (If anyone has one from a Megateuthis, I'd love to see it! - they don't seem ever to be preserved.) Given to me by a friend, it is in a nodule from the Jet Rock (Upper Lias, Lower Jurassic) of Port Mulgrave, north Yorkshire coast. It must have belonged to an exceptionally large Acrocoelites trisulculosus which is probably the only belemnite to occur in this bed. It's a large species anyway - typical rostra of it are 5 - 7" long but about 9" has very rarely been recorded so a bit longer may be possible. Photo 6: Not having such a large Acrocoelites in my collection, I've done a conservative mock-up of it with a smallish (9") Megateuthis and another piece of phragmocone which is my second largest... A total length of 20 - 24" seems about right. Photo 7: For comparison , I have a complete but crushed example of A. trisulculosus about 12" long, the rostrum being 6.5". 1) 2) 3) 4) 5) 6) This should probably be stretched more... 7) A normal size Acrocoelites trisulculosus with crushed phragmocone (the strange ridged structure on top of it is a crushed on-edge Harpoceras shell mouth)
  7. Jurassic Bone Block ID? (Yorkshire, UK)

    Hi all, I recently found this massive bowling ball sized rock at Saltwick Bay near Whitby on the Yorkshire coast (Northern England). It is lower to middle Jurassic, i think about 180-170 million years old (possibly the Whitby Mudstone Formation). As you can see it it's full of various bones, which occur on almost all sides of the rock so they are probably running right through it. Prep for this one is going to be a nightmare i can tell and i don't have the right tools, but for now i really just want to try and figure out what i've got. I think it's fair to assume the bones are associated. The options for this bit of coast are fish (Gyrosteus), ichthyosaur, marine crocodile, plesiosaur or dinosaur. I was hoping based on the cross sectional shapes of some of the bones, and the texture of the bone itself, someone would be able to narrow down what it might be. Fish or reptile would be the first thing to determine. My obvious first assumption was marine reptile, but some of the fish on the Yorkshire coast like Gyrosteus are also huge (5m long) and i'm not very familiar with their bone structure. In this picture, i thought the rectangular bone towards the bottom might be a vertebra in cross-section. If so, from what? Could it be the edge of an ichthyosaur vertebra before it dips down in the centre? This bone is the biggest in the block, about 8 cm long and 3 cm thick. Continued in the next post!
  8. CORAL COLONY

    Now, i found this when i was seven or eight years old, on the cut down to the beach at Kilve in Somerset, South West England. It was buried in a band of blue/ grey clay in the Psiloceras planorbis zone of the Blue Lias , Lower Jurassic. Although i'd found many lovely fossils before this was my first exceptional, "WOW!" find. I still don't know what it is and that was 45 years ago. A colonial coral colony yes, but i don't think it can be Liassic? A derived fossil from the Devonian or Carboniferous seems likely, but which one? And it shows very little signs of having been transported huge distances, as it's quite a way to the nearest relevant outcrops of those ages. Here it is :
  9. Fossil of the Month, January 2015. Prepping details here: Jan 2015 finds of the month A partial, extremely rare, many armed starfish, the genus was assigned to a new family Plumasteridae in 2011: A. S. Gale. 2011. Asteroidea (Echinodermata) from the Oxfordian (Late Jurassic) of Savigna, Départment du Jura, France. Swiss Journal of Palaeontology130:69-89 This is from the same area and formation as the holotype of its species. The distinctive ossicles are common as disarticulated elements in sieved samples from Pliensbachian to Oxfordian. Excerpt from the above paper: Family Plumasteridae nov. Diagnosis: Multiarmed (12–22 arms) asteroids with broad adambulacrals which occupy the entire actinal sur- face of the arm and V distally: adambulacrals concavo- convex, 5–8 specialised interlocking articulation ridges and grooves articulate with ridges on adjacent adambulacral (modified ada2-3); abactinal ossicles with numerous lateral projections and embayments, and each carries a central large convex boss with which long, glassy, ridged spines articulate. Type genus: Plumaster Wright 1863, is the only genus included. It ranges from the Pliensbachian to the Oxfordian. Discussion: The Plumasteridae is established for the distinctive multiarmed genus Plumaster. This is distinguished from other multiarmed spinulosans such as solas- terids by the unusual boss-like spine articulations of the abactinal ossicles, and the highly modified adambulacral ossicles, which articulate by means of ridges and grooves.
  10. An unusually complete specimen although crowns are well known from this location. It is an early comatulid (feather star) and has a very short stem consisting of only six or seven columnals, all of which bear cirri. Reference: Simms, M.J. 1989. British Lower Jurassic Crinoids. Monograph of the Palaeontographical Society, London:1-103, pls.1-15 (No. 581) This was Invertebrate/Plant Fossil of the Month March 2015
  11. As often the case with brittle stars and other starfish, this shows the oral surface and is on the underside of the sandstone bed. The bed below it is a shale and the base of the sandstone represents a sudden influx of sediment which preserved the brittle star nearly intact. This was Invertebrate/Plant Fossil of the Month Sept 2014 and Fossil of the Year 2014.
  12. Hi I hope someone can help me with this! I found these two very small fossils when wet sieving lower lias shell bed. They are about 2mm in size and look a bit like a cross between a crinoid and a bone-like substance. They are so small they were very hard to photograph even using the super-macro function on my camera but hopefully they are good enough for somebody to perhaps recognise what these are? I'd be very grateful as I am mighty curious! Thanks in advance. Sam
  13. Northampton Ammonites (U.K.)

    Hi guys, A friend of mine from work has recently found a field in the small village of Bugbrooke which is currently littered with ammonites eroding out of the surface- as he knows I'm studying Palaeontology next year for my masters he has decided to give a few to me to both prep and also try and identify. After a little inspection I was thinking that the ammonites he has provided me is most Lilkly Dactylioceras and Hildoceras. This would make sense as the local geology is Jurassic mudstones often capped by ironstone on top. Of course this is conjecture and ammonites are not my specialty.

  15. Unknown UK bivalve

    Unknown fossil bivalves from the UK, the only clue I have so far is what appears to be written on the side of the matrix which is the word “Lias”. I've looked in an old edition of The British Mesozoic fossils book but can’t quite find a possible match.
  16. Ammonite?

    Hello , I try not to make spelling mistakes . Does this little fossil , perhaps the size of a 2-euro coin , a small ammonite ? She looks different from others I already found . Someone can help me?
  17. Is this a Nautiloid ? (2)

    Is this a Nautiloid ,also? Am I lucky today?
  18. Is this a Nautiloid?

    I found this fossil today,in Serra Aire e Candeeiros,Porto Mós. Is this a Nautiloid? Can anybody help me please? It is lower jurassic (i think) Thank you
  19. To mark the occasion of this new sub forum for museums. I would like you show you some wonderful stuff in Teylers Museum in Haarlem, Netherlands. This is actually the oldest museum in the Netherlands and thus also has some really cool history attached to it and it's specimens. http://www.teylersmuseum.nl/en Besides fossils this museum also holds an art and science collection. The museum is just as beautiful as the specimens in it and a true time capsule. While it is quite a small museum, it's charm is worth the trip alone. Even the cabinets are pretty. It even has a few world firsts, such as Archaeopteryx and Mosasaurus. Now on to fossils! One of the most important specimens on display here is one of the Archaeopteryx specimens. This is actually the first Archaeopteryx as it was found before the feather and the London specimen were found. But for a long time it was labeled as a Pterodactylus. Only later was it found that it was in fact an Archaeopteryx. While very incomplete it is one of the larger animals of the genus (the third largest I think). the specimen consists of slab and counter slab. If you look close you can still see the vague impression of the flight feathers on the wings. It also very nicely shows the keratinous sheaths of the claws. Archaeopteryx lithographica Along with Archaeopteryx Teylers also has a very nice collection of the Jurassic of Solnhofen in Bavaria. They have a number of Rhamphorhynchus skeletons, lizards, fish, crustaceans and squids complete with tentacles and inksacs. Rhamphorhynchus Various fish Homocosaurus maximiliani Various critters
  20. Here's a specimen I found last August on the Yorkshire Coast, near Whitby (UK) and have recently got prepared. I didn't prepare it myself, but sent it off and have just got it back. What do you think? The specimen is a Zugodactylites braunianus, and it is from the Upper Lias of North Yorkshire. It's about 185 MYA.
  21. Here's a brief description of how I prepped the Yorkshire coast Palaeocoma milleri that won last month's invertebrate competition. It was found in the middle of the top face of large, hard sandstone boulder. The tide was coming in quite fast and I wasn't sure if it was extractable in time - but after a frantic hour of chiseling a channel around it it was ready to lift. Always a scary moment but the Estwing bolster did the job . The resulting block is 12" x 8" x 3". The curly arm on the left was loose and broken into four pieces - these were carefully packed and glued back on at home. The next step was to rough it out with an air pen and abrader to see how far the arms went. Sadly, none of the others were as complete as the exposed one but that's often the way with brittlestars... Also, the surface of the central area is slightly corroded by the acid from a decomposing thin layer of pyrite - a common problem from this formation. I also used some potassium hydroxide flakes which is why the matrix has turned red-brown along the top arms. Then more work with pen and KOH to expose the centre disc and bring out the arms: It was then soaked for a couple of days to remove KOH. After more penning and tidying with the air abrader, the pen marks were ground away and that's as far as I've taken it - there's certainly scope to do more but I'm leaving it for now.
  22. Help Ichthyosaurus Bone ?

    Hi everybody. I came back with this specimen. My sister found it recently but I don´t Know What is this. We know is a bone, but we are not sure if this fragment is an Icthyosaurus bone or other. What do you think. ? From Lias sediments, sea enviroment.

  23. Lower Jurassic Ammonites

    Hello, I've just finished cleaning these two ammonites (I think they're the same) from the Lower Jurasic ("Lias") of Lincolnshire, England, and was wondering if someone could help me work out what they are please? Thanks! https://flic.kr/p/neZBmP https://flic.kr/p/neZMzC https://flic.kr/p/nwvPWj https://flic.kr/p/nuryi7
