I found this fossile last summer at the beach of Randsfjorden in Norway, Kalvsjøen formation, from late Katian, late Ordovician, but cannot figure out what it is. The speciemen is about 3 cm long and geodized in the middle. Does anyone have an idea what it can be? Thanks for any suggestions. Martin

I found several kinds of gastropods and two other uknown fossiles in the Kalvsjøen formation, late Ordovivcian at Hadeland in the Oslo field, which I like to share. The limestones in this formation are called 'the Gastropod limestones'. Can anyone please help ID some of these fossils. I guess some of the gastropods cannot be ID-ed, but I hope some of them can be at some level and the other unknown animals. Any help are appreciated. The first rock (the first 3 pictures) has one strange fossile (to the left) and several small gastropods, some very small, which I could only see by taking several pictures from different angles and by using different light sources: Enlarged left side: Picture 3, the right side enlarged: The next, rock no. 2, has a nice shape of the cross-section of a gastropod with 5 levels or spirals: It also has a strange very small fossil, near my finger. Picture 4 Pict. 5 Pic. 6-8, enlaged small fossile: Rock 3, picture 9, another gastropod in cross section, size is about 2 cm broad: Rock 4-5, picture 10-11, two very small and nice gastropods, which I did see only after I enlaged a picture I took of the rock with a microscope:

In the Kalvsjøen formation in the Oslo field I found these two stones. I wonder if they are gastropods or something else? The formation is of a rawthyean age late Ordovicium, the last period of Katian, before the Hirnation extinctions. Next fossil:
