Hi everyone, I got offered this pair of marine reptile teeth as those of ichthyosaurs, but am having a hard time making my mind up about their identification. I'd therefore like to ask for your opinions. The teeth were found during works around Nancy back in 2004, and, based on other ichthyosaur finds from the region, likely dates the Toarcian stage of the Early Jurassic (though, from what I can tell, Oxfordian marine deposits are also accessible in the area). This makes them roughly the same age as material from the Posidonia Shale/Holzmaden and Whitby, bu

I keep finding small rocks at the base of banks alongside the road, around the area where I live in Bath, UK. Most of them contain bivalves but I keep coming across this shape which I can’t recognise (picture 1) Picture 2 is a close-up of rock A which seems least weathered. I think these are the imprints left behind by something but I also have an example of what I think could be the actual object itself (please excuse my lack of terminology!) but it’s tiny compared to the other three examples (picture 3) Any help with this would be great thanks.

Dwarf Brachiopoda from early Toarcian Koninckella fauna in Portugal (Polymorphum Zone, Semicelatum subzone), comprising particularly Koninckella liasina, Nannirhynchia pygmaea and Pseudokingena deslongchamps. Koninckinidae became extinct in the early Toarcian and has minute size and peculiar shape (that is very similar to that of the Paleozoic strophomenids).

A lovely 18" belemnite slab I've bought for my birthday (birthday belemnites are a bit of a tradition!). From the Jurassic Posidonienschiefer (Toarcian, Upper Lias) of Holzmaden - a very interesting and unusual selection of mostly the same species, one with a nice epirostrum. Not quite sure of the actual species, but it's close to Acrocoelites subtenuis and A. gracilis - neither of which usually have epirostra (the squashed bit at the tip of photo 2). It also contains a couple of bonus teeth including a Hybodus type which Sebastian @belemniten tells me is a rarity there. Ap

Found a rather large and partially well preserved ammonite in ammonitico rosso dating early to middle Toarcian in the mountains of Epirus, Greece. Partially preserved because the other side was exposed and totally flattened. I am actually puzzled by the flattened state of the inner whorl as opposed to the outer whorl and center which appear intact. The shine is due to the paralloid-acetone mix i coated the specimen with, to prevent further deterioration. Would appreciate any suggestions to the species.

I've just purchased a fine slab of belemnites from Holzmaden and the stratigraphy is given as Posidonienschifer, Lias epsilon II-102. I know that epsilon is Lower Toarcian but please could anyone enlighten me about the II-102? I particularly want to correlate this accurately with Yorkshire, if possible! @belemniten ? EDIT: I've just checked the seller's other material and one that I'd expect to be from the same beds is given as "II-12" - so @oilshale is almost certainly right with his answer below, and it see

On Saturday, whilst - as I thought - recovering from a cold, I spent six hours in the blazing sunshine, hunting for ammonites in the inland exposures of the Beacon Limestone in Somerset, England. It involved a lot of physical exertion, especially for someone who was ill, with the result that it's now two days later and I'm as sick as a dog - and on my 40th birthday, too. If that's not depressing, tell me something that is. Whilst I'm feeling sorry for myself, at least I can take comfort in the fact that I made some pretty good finds. These are just the most photogenic finds, t

3x3.5cm. Complete with selenizone (Slitband) Late Toarcian From Zaouiat Cheikh Tadla Azilal Province Morocco -
Spent two afternoons in the workshop prepping some ammonites from the Beacon Limestone, a Toarcian deposit exposed in many places around Somerset, UK. Had a fair few disappointments, including several very large ammonites (for this area - about 8 inches) which had no centres. That's common for ammonites from this location, which is a pain because it often takes a lot of prep through sticky, tough rock before you can tell whether or not there's a centre. But there were some nice ones. I had cautiously high hopes for this large harpoceras... Which
