@AndrejPaleobio Yes, I love it! I remember hunting for fossils in a very old church in Lund with the same limestone.
Fun fact: Despite being called "Orthoceratite Limestone", most of the cephalopods are actually endoceratids of the genus Proterovaginoceras, though your first image actually shows an orthoceratid. The coiled one is a tarphyceratid, while the ones in the cathedral are all endoceratids. Cool stuff!
@AndrejPaleobio Nice, and great selection of taxa!
The first looks like Ancistroceras, a lituitid, which are mostly straight except for the coiled apical part (only partly visible).
The second one is not well visible but my guess would be an endoceratid, based on the apparently large marginal siphuncle.
The last one is a nice orthoceratid, well recognisable by its relatively narrow central siphuncle.
