Hi all, Bought this tooth online a while back. It was sold to me as "Ichthyosaurus platyodon" (which I understand to mean Temnodontosaurus platyodon) from Lyme Regis. Likely found by the seller themselves, as I know they occasionally collect fossils there. However, for the following reasons, I'm not sure about this attribution: Overall, the tooth doesn't look like your typical ichthyosaur tooth to me: It has more of an oval rather than round cross-section It's labolingually flattened Messial and distal carinae run the full length of the cr

Whitby find. Jurassic, Lias.

Hi I decided to display a few of my Whitby ammonites. Most are self found, some bought. Some are prepped by me. Some prepped by other people. One of the ammonites on the top shelf isn’t from Whitby. Guess which. Where’s it from and what is it? I’ll post some close ups in due course. Thanks for looking.

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

I haven't been collecting from the Lias of Dorset or Somerset (in the UK) for a couple of years, for various reasons, obviously Covid being a major one over the last year. I'd begun to think I'd not really be able to go much again, but then we moved to Somerset, close to many exposures of material from the lower Lias (Hettangian, approx 200m years ago). So these days, I'm able to walk on the beaches every day. Living the dream! So far I've only found two small icthyosaur vertebra, but ammonites and bivalves have been a little more forthcoming. Here's a few photos of so

From the album: Early Jurassic Ammonites from Southern Germany
20cm. Augmented with Apoxie Sculpt from 1-3 o'clock in the first photo. Found on a plowed field in Klettgau, southwest Germany near the Swiss border where the stratigraphic info stated merely Lower Jurassic. Probably originates from the Early Pliensbachian. -
Looking for information on a historic Jurassic squid fossil
The Amateur Paleontologist posted a topic in Questions & Answers
I was recently skimming through one of William Buckland's papers (in Geology and mineralogy considered with reference to natural theology). In the paper, he discussed (and illustrated) a squid fossil that had been found by Mary Anning, in the Lias/Jurassic of Lyme Regis in 1828 (see pic below). Would anyone happen to know in what museum this fossil currently is? Taken from Buckland (1837), plate 44'', fig. 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 level

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.

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

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. -

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 bee

An unusually complete specimen although crowns are well known from this location. It has a very short stem consisting of only six or seven columnals, all of which bear cirri. Once thought to be an early comatulid, it is now thought to belong to a separate lineage of nearly stemless pentacrinitids (Hess 2014). References: Simms, M.J. 1989. British Lower Jurassic Crinoids. Monograph of the Palaeontographical Society, London:1-103, pls.1-15 (No. 581) Hess, H. 2014 Origin and radiation of the comatulids (Crinoidea) in the Jurassic. Swiss J Palaeontol 133, 23–34 Hess 2014

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

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 distan

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 Palaeontology 130:69-89 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.

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.

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

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.

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.
