Hi all! Another report in continuation of the previous ones. This time I had 2 days to visit the site and used them to monitor my preferred 3 km of the shore. It was literally the last days of autumn, so by the end of my stay snow started to slowly cover the place for the 5 upcoming months. The water level was a bit lower than in 2020, but much higher than last year. This time 3 boars on the shore: one of them

This time on our field trip we tried the late jurassic deposits of the northern french coast. those spots are a bit harder to prospect, but from time to time you can find vertebraten material there. This time we found quite a few Hybodont remains, 2 realy nice teeth and a spine. we also found a little piece of marine reptile bone and fish scales.

This time I settled down to make a copy of my very best Crussoliceras crusoliense ammonite from the Early Kimmeridgian at the ditch in the Upper Danube Valley. It's ø is 16cm. and it has a small Glochiceras sp. tagging along at the mouth aperture.

Hi all, I bought this Kimmeridgian plesiosaur tooth from the Faringdon sponge gravels a while back. It came identified as Colymbosaurus sp.. At that point, I simply accepted this identification, seeing as the teeth of Colymbosaurus (or, at least, what's suspected of being Colymbosaurus) were already known from the Etches Collection and I didn't really have the means to verify the ascription from online sources. Today, however, The Etches Collection posted a video on Kimmeridgian plesiosaurs on their YouTube-channel, which make it abundantly clear that my specimen doesn't correspond to Colymbosaurus (video referenced below, as is a photographic excerpt of the teeth). The teeth of Colymbosaurus are not only subtrihedral but gracile in shape, they also have very strong striations - much stronger than in my specimen and almost pliosaur-like. The striations on my specimen, on the other hand, are way more similar to those of the Oxford Clay Tricleidus seeleyi, with very fine striations all along the tooth, a round cross-sections and (obviously) without carinae (just to rule out marine crocodile). My question now is: can my tooth be identified as to species or even genus? Could it be that the temporal range of Tricleidus extended into the Kimmeridgian? Might this tooth belong to Kimmerosaurus? Steve mentions in his video that there are more plesiosaurs that remain to be described from the Kimmeridge Clay, so, with that in mind, should I just classify mine as "cf. Crypticlididae indet."? Any ideas and suggestions welcome, but will just also tag @paulgdls and @DE&i.

I brought a piece of marl from my trip to France that had some interior bits sticking out. The location is Pointe du Chay (south of La Rochelle) and age Kimmeridgian - Jurrassic. Two of the pieces I prepped out this weekend (first successful attempt in doing so despite too much glue). The tube like structure and what I first expected to be a bivalve from the outside but I don’t know any with a hexagonal pattern. thanks in advance for your help

Hi, i recently received those very nice sponges from @badeend. I asse they're all Hexactinellids. I know identfying sponges even when you have them un grand is a hard thing to do. Any help to try a more precise ID is greatly welcome. Here is the number1, a glass sponges ? Kimmeridgian, Kalberbeg, Netherlands
