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.

An extreme morphology, much of the length consisting of an epirostrum - an overgrowth and extension of the normal rostrum. This may have been aragonitic and partially organic and is frequently crushed. Described under Youngibelus tubularis: Doyle, P. 1990-92 The British Toacian (Lower Jurassic) Belemnites. Monograph of the Palaeontographical Society, London: Part 2, 50-79, pls.18-28 (Publ. No. 587, vol. 145) Cuspiteuthis Abel 1916 was re-established as senior synonym of Youngibelus Riegraf in: Riegraf, W, Janssen, N.M.M & Schmitt-Riegraf, C. 1998.

Hi. I found this on the Yorkshire coast, UK (Jurassic.) Is it a dinosaur footprint? The 'footprint' isn't clear so I have drawn an outline on the second photo. The possible footprint measures 6.5 inches. Dinosaur footprints are quite common on the Yorkshire coast. Thanks, Daniel

Well decided to work on a couple of bits last night for an hour, the bone is from Kettleness and is one I have been thinking about having a go at so finally decided to get it done. The ammonite was picked up from Port Mulgrave it had a nice ridge showing but as I removed the extra matrix of it a Hildo appeared. It is looking crushed so not sure how the middle will be, but if it is ok I may prep the other side to expose both ammonites.

Hi. I found this in West Yorkshire, UK in the Pennine Lower Coal Measures formation (upper Carboniferous). It is in a Marine concretion. It contains what I think is a Phyllocarid but when I was looking at it today I noticed a Tully monster shape. I'm 99% sure it's just a fracture in the rock rather than anything interesting but I decided to post some pictures here just to be sure. Thanks, Daniel

Hi. I went fossil hunting today in an old coal mining tip in South Yorkshire, UK. Almost all of it is overgrown and there is very little rock which contains good fossils but it is possible to find some nice fossils. Years ago, the tip caught fire, which changed the colour of the rocks. Most of the rock is now red or pink. The fossils at the site are from the Pennine Middle Coal Measures formation, which is around 312 million years old. Good quality fossils in West or South Yorkshire are very rare, mainly because the rocks which contain the best fossils are rarely exposed. When they are exposed, it is usually in places which are very steep and difficult to get to. The Coal mining tips like the site I went to today are quickly becoming overgrown and most of them don't contain any good fossils. The rock layers which contain the best fossils in the British Coal Measures seem to be very thin. The marine bands, for example are usually only a few inches or a foot thick, so finding them is very difficult. In the sites where I find plant fossils, the layers which contain the good plants are all very thin, and usually there are unfossiliferous rocks above and below the layer. West and South Yorkshire are therefore not very good for fossils, but rare fossils can be found. I have found Shark teeth, fish teeth, scales and bones, a millipede, coprolites, a shrimp, goniatites, bivalves, plants, ostracods, burrows and tracks in West and South Yorkshire. Overall, the most important thing is to know the geology of the area well, and then with a lot of research it is possible to find sites which have fossiliferous layers. Today, I didn't find much, however I did find this plant fossil. It seems to be a part of a large Cyclopteris sp which is covering what I think is an Asterophyllites sp. Daniel

Complete pyritized shell.

This species gives its name to the zone and subzone at the bottom of the lower Toarcian. This very fine-ribbed specimen of the genus Dactylioceras is for me a fine representative for the legend of St. Hilda, the Abbess at the monastery in Whitby ca. 650 A.D. She wanted to build a convent there as well, but the grounds were infested with snakes, so she prayed so intensively that all of the snakes were turned into stone. Since then they are known as snakestones. I found this sample pretty well as is with a head that reminds us of a snake. Literature: Howarth, M.K.

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.

Hi, i was hoping someone could help me identify whether the following photos are a concretion or a fossil. The piece was found poking out of a lump of clay fallen from the cliff at Robin Hoods Bay, North Yorkshire, UK. It looks like one end is broken off and there is an outer layer which is a mid grey colour with brown patches and the inner is a much darker grey to almost black. The dimensions are around 9" by 4" by 3". Any help much appreciated, thanks Simon

I'll like to check out are these Arnioceras ammonites pyritized? They are from Yorkshire UK. I want to know in your opinion, are these ammonites pyritized or non-pyritized?

I've just come back from a trip to Yorkshire where I managed to do a little fossil hunting and was lucky enough to find this ammonite. The problem is though is that generally the preservation in the area wasn't great and this one is clearly covered in a mudstone/ shale type of rock. However I think it might be worth trying to remove the surrounding rock because the small bit which I can see seems to have preserved fairly well. However I don't know the best way to remove it, see i'm not very comfortable with chiseling it away because I'm fairly new to this so would probably end up ruining it! I've been told that it may work if I was to put it into the oven to warm it up and then put it into cold water which could 'shock' the fossil to break along lines of weakness but I'm not sure if it would work or not. I've tried to post a picture of the fossil here but I'm not sure if its worked so if not here's a link: http://s1069.photobucket.com/user/zozzy-zebra/media/IMG_0003_zps69eb4cbf.jpg.html Any suggestions of how I can remove my ammonite would be greatly appreciated. Thanks

I recently got round to prepping a few ammonites from my collection - I collected them during the summer (August) at the Yorkshire Coast (UK), but have only just got round to prepping them. I thought I'd share them with you. I'm not an experienced prepper, so I was practising on these ammonites. I am pleased with how they turned out, although I still have a little bit of work to finish some of them off. If anyone else wants to share their Yorkshire ammonites that would be great; once we get a thread going I'll post some of my other specimens. All of these ammonites are from the Lias of the Yorkshire Coast, UK, and were prepped out of hard limestone nodules. I used the Chicago Pneumatic from start to finish on all of theses ammonites, and then I gave them a light coat of beeswax.
