Hello all I'm currently on a trip in France, near Chaumont. The geological maps say this area is middle to upper Jurassic, but other sources say it's Rhaetian (Upper Triassic). I found this tooth in marine desposits, clearly because 99% of all finds I do here are molusks, bivalves etc. They range from less than one cm to over 15 cm. The tooth is about 2 cm. What do you all think? As far as I know no Ichthyosaurus fossils have been found here. Thanks

Visited Port Mulgrave on the 10th March and found some lovely Ammonites then walked the shoreline to Staithes. Those of you who know the coast will be aware that whilst there are fossils at the Staithes end, it is Port Mulgrave and a few spots in between that are the most productive. Imagine my surprise, with the Cod and Lobster pub in sight at the end of my trip, when I looked down at the smaller of the two pieces just sitting there. After an hour searching the area I found the larger part which is a perfect fit. The pieces are very weathered and I think may have been exposed high up in the upper lias for quite some time. I have been back twice but nothing else has come down yet. The rest may well be up there. There is no pyrite present but it is too advanced a prep job for me so I have taken it to Mike Marshal of Sandsend. I know you can't make a silk purse from a pigs ear but he will no doubt work wonders. It is my best every find and I don't know if I will ever experience the same excitement fossil lint. Amazing.

Please could someone advise me on the permission required to remove a fossil. At low tide on the North Yorkshire coast near Port Mulgrave I discovered 5 visible ribs and some verts exposed under seaweed. The fossil appears to be limited to this with no paddles or jaw etc but it is still my best find. The area to be removed is approximately 60cm by 50cm. It is located about 10 meters off shore and will be exposed again next week. I removed a rib in three parts and would be able to remove the whole plate with tools. Can anyone tell me whether I need permission to do this and if it would be ok to use a cordless power tool in the process. Best regards Steve

I think one is a rib, but i'm not sure about the other bits, cheers.

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!

Can anyone help me id this vert. It came with a batch of Ichthyosaur bones I bought from Dorset, but it not like Ichthyosaur verts I usually get.

I have a question if Ichthyosaur is considered a reptile how come it gave birth to its young live? What separates it from mammals?

Title says it all really. Can anybody help? @abyssunder @doushantuo @Fruitbat Thanks! -
Yesterday I was again in the quarry Kromer near Holzmaden (Lower Jurassic) and I found a really nice tooth ! The tooth is about 2 cm long and 1 cm wide ! I think its one of the biggest tooth I have ever found ! Its a Temnodontosaurus tooth, which is a large Ichthyosaur. In the "Schlacke" (a specific layer) you can sometimes find smaller teeth but such big teeth in a good condition are very rare. I am really happy about this one Especially because there wasnt much material there, so it was a lucky find ! The prep took about 4 hours. - The quarry, where I find this teeth will close during winter so the tooth is also a great completion of this year !

Hi there. I recently purchased a big box full of shale, containing a number of disarticulated ichthyosaur bones from South Wales. Mostly ribs, but there's also a humerus and one or two other unidentified bones too. It's not an amazing piece, but I'd consider it good practice. I've been trying to work out how to prep it. It's in many pieces, and putting them together is a bit of a task in itself! As you can see from this terrible photo, I've made some progress. I've numbered the joins so that their positions can be found easily, and drawn in marker pen on the surface of the shale where the bones appear to run beneath. I'd appreciate any advice from anyone that's done this sort of thing before. This is how I intend on proceeding: 1. Complete the jigsaw - and hope it all fits together! 2. Prep each piece to expose the bones 3. Set the pieces onto some kind of backing - not sure what? 4. Tidy up the prep, and use epoxy clay to fill the cracks. If anyone has any suggestions, I'd be very grateful. I've never dealt with any icthyosaur material before.

So I drew a paleo-reconstruction of a noteworthy but sparsely-known apex predator Temnodontosaurus eurycephalus, which was believed to be the top apex of the Early Jurassic until the rise of proto-pliosaurs like Rhomaelosaurus. Unlike its famous squid sucking sister T. platydon (metaphor, not literally), T. eurycephalus had a thick skull with deep jaws and large robust teeth suggesting a macropredatory diet and probably fed on other ichthyosaurs, plesiosaurs, and anything else that it could swallow (Also, growing lengths of over 30 feet, it probably could swallow everything other than another Temnodontosaurus) This is actually my first time finishing a paleo-reconstruction using only a pen tablet and photoshop (All my other drawings were either unfinished or done on paper). I used a Huion 1060PLUS drawing tablet and Photoshop CS6 to draw this. Took at least 3 hours to draw, and I heavily referenced the holotype skull to draw the head. Turned out pretty neat, but I don't know if I should color/shade this.
