So for the last two and a half weeks I’ve been camping in the Ardèche region in southern France. After a long, exhausting trip of 13 hours we finally arrived. We put up the tent, read a book and went to sleep so we would be fit for our first real day of our vacation. At the first day, we did visit the museum I showed in this topic: After that, the real work started. This big pile of rock was just dumped at the edge of the road. After a few minutes we found our first complete ammonite. Spot the ammonite The whole region is filled with these small piles of rocks, so as long as you just keep walking, you’ll find them… The region itself is beautiful too. Anyway, except two beautiful little ammonites, the first day didn’t really work out. The next day I walked a little further from the camping (like little as in 10km). Totally worth it! I found an amazing spot were marls eroded away and just left tiny ammonites. When I found them I immediately thought of an old topic by @Max-fossils who went to Carniol some time ago. At first, I thought it was identical, except this spot was a lot smaller, not as rich and with a couple of different species. I think I spent about 40 hours at this spot, and I think I found about 150 tiny ammonites, from at least 8-9 different species (but I’m far from an ammonite expert). I think these are lower Cretaceous, but I am not sure on a more precise date. How most of the place looks. Covered with tiny ammonites that resurface after heavy rains (which occurred three times during my stay, so I could keep searching at the same spot) The spot, kind a steep wall (me for scale). Anyways, time for some of the finds (my good camera broke down so I do this with my phone): I think these are Aconeceras nisus, the most common species.

Good morning everyone! I have collected many vertebrate fossils from Tournaisien dolomites, Carboniferous marls and Early Carboniferous- Permian carbonated sandstones. I tried to identify the age of the erratics for a very long time and I think that all three types of erratics are from Carboniferous or Permian periods. There are many rhizodonts, megalichthyids, lungfish dental plates, one ganoid scale, small shark tooth and even one big ptyctodontid placoderm tooth (I have doubt if it is more famennian like or could be Tournaisien). In the same Tournaisien dolomites I have found many crinoids, brachiopods and molluscs. From brachiopods the Productids, spiriferids, rhynchonellids are very numerous, there are also some athyridids and Orthotetes specimens. In the marls the clam shrimp remains are often, plant (like horsetail) remains are very rare, the majority of fishes are rhizodonts and there is also one specimen of two skull bones from small amphibian. Please help to confirm vertebrate fragments (especially Sagenodus lower jaw and Ctenodus upper jaw plates), for the age confirmation I also will show invertebrates if it is needed. Best Regards Domas
