Hi ! So I went on a walk in some marls in Lozère, France. Usually, I find some amonites and belemnites but this time I decided to change from my usual spot and searched around. I found an isolated marl which is a couple of kilometers away from the main marls which are known to be from the Toarcian. In the whole region (région des grands causses), marls can be either from Toarcian or Pliensbachian according to french wikipedia (https://fr.wikipedia.org/wiki/Marne_(géologie) ). Anyway in this new marl, I didn't find the same fossils as usual, at all. I found mainly gastropods, very sma

Hello, I have recently bought this fossil as an Acrocoelites oxyconus, from the toarcien of Tournadous, France. But after seeing the photos of Ludwigia, and others in the internet, it seems that it is not Acrocoelites oxyconus. The fossil looks to be broken and glued: Thanks!

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
