Almost every multi-storey building in Sweden from around 1900 has a staircase with steps and landings made from that limestone. As far as I'm concerned orthoceratites are the first, most basic fossil anyone learns!
@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.
We had window sills of Solnhofener limestone.
As a child, undergrad, I used to spend hours exploring the fossils. Some of them, shell and belenmonite fossils, where of quartzite sparkling in the light
