I bought this ammonite at the MAPS fossil show recently and I'm going to make a unique display for it. The old label that came with it is what caught my eye at first then I picked it up and held it up to the light. The calcite filled chambers are translucent and "glow" nicely when back-lighted. I have a few ideas on how to display this guy but would like some input. I will post pics to this thread when I have started to work on this so stay tuned. Thanks mikeymig

I took a walk over the fields yesterday in the Wutach area. The farmers are preparing their acres again, so it was time for a stroll. The sun was shining, so I didn't get all that much muck on my boots, but nevertheless, I'm having to vacuum the driver's side of the car today. There wasn't all that much worth keeping this time around, but I did hang onto this one. A Myophorella clavellata bivalve with a length of 8cm. They're not at all common in our area at this particular Bajocian stratigraphic level, so I was glad to have found my third and best preserved one in about 10 years. It's missing a bit from the end, as indicated in the second photo, but that's not so important. The second one is a recent gift from a friend who says he has enough of them, but I just can't say no to a nautilus, although I already have about 50 of them. It's just the very inner whorls of what probably had originally been a pretty large Cenoceras sp. from the Sinemurian, but I think it's pretty cute at 5cm. diameter.

I found this in Jura, Switzerland, near Courtedoux, about a kilometre from one of the sites where dinosaur tracks were discovered in 2002 (https://www.myswitzerland.com/en-us/dinosaur-traces-courtedoux.html). I was wondering whether it was a fossil of something, and if so of what?

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)

Hi - just introducing myself. I live in the UK , near London, luckily with family on the Jurassic coast of Dorset. Ive always been into fossils. My interest is in searching for reptile remains when down at Lyme Regis or paleosculpting things when im not there!

Hi, We found this at Port Mulgrave today and are not sure what this is? Can anyone help? Sorry if this is obvious but we are new to fossils and do not have a lot of experience.

Hi guys/gals, found this huge Nautilus this Saturday, still unprepped and I'm still in a bit of shock, once prepped I think it will be unreal... thanks, Alan.

Out hunting Jurassic coast yesterday, found this nodule containing what looks like the underside of a skull, symmetrical on both sides apart from one side is worn, if it is I was thinking croc or possibly Plesiosaur but it looks fish like to me, either way there is a lot of bone in there, any suggestions ? Thanks, Alan.

Chitinobelus, a strange and rare belemnite? from the Posidonienschiefer
TqB posted a topic in Member Collections
Extremely rare, I never thought I'd get the chance to acquire one of these so I was very pleased when one came up for sale. Chitinobelus acifer Fischer 1981, a belemnite (or possibly belemnotheutid) whose rostrum was originally composed of aragonite with organic material. As a result, it's preserved as a compressed organic film with the aragonite lost to diagenesis. Belemnites are nearly always mostly calcite (largely thought to be primary) and preserve 3D in all sorts of rock. There is argument (quite complex) over whether this is an unusual aragonitic belemnite or something a bit different. There are prominent striations which are similar to those in the "normal" belemnite, Salpingoteuthis. From the Jurassic, Lower Toarcian Posidonienschiefer of Zell (not far from Holzmaden, Germany). As far as I know, this is the only locality it's been found. Phragmocone chambers just visible.

The last 2 days where a little improvised fieldtrip, I itended to go only on saturday, but on the last minute I decided wit my girlfriend to leve on friday untyl saturday. we left Fryday afternoon to the ardennes area, my first stop that I wanted to make was a recently reworked roadcut near Chimay, A friend of me found a few very nice Receptaculites neptuni at this location. I followed his instructiuns to get there and once at the spot in took only a few minutes to find the first fragments of the sponges and a few pieces of indetermined Orthocerids. Although most of the site was already prospected by other people, after halsf an hour, I did find 2 very nice specimens of the Receptaculites neptuni. After this site we went even further south and crossed the border to France where we found a little "auberge" to spend the night and have a decent supper. in the morning we went to the area of Novion Porcien where a few abandoned quarry in the woods deliver Oxfordian fossils, mainly bivalves and gasteropods, but also Sea urchin spines and sea urchins. Although those last ones where a little harder to find we did get a coupel of complete Hemicidaris sp. On our way back home we stopped near Nimes in Belgium, again in Devonian deposits. Her we went to an old roadcut in the forest where we could find small but beautifull trilobite parts from Asteropyge. most of the time only pygidium, but we did find 3 cephalons. This was the last prospection of our little trip before getting back home with quite few interesting fossils. it was a welcome change to my usual cephalopods Manticocerasman

Can anyone ID these dinosaur fossils from Ambondromamy, Madagascar
-Andy- posted a topic in Fossil ID
Hi all, a seller recently offered this dinosaur claw and tooth to me from Ambondromamy of Madagascar. Truth be told, I know next to nothing about dinosaur fossils from this region besides there being massive predatory reptiles there. I was hoping someone could shed some light on what these could be. I am not even sure if the claw is dinosaurian. Thank you.
