Hello On my second fossil trip this year I decided to do a little exploration in an area which was hitherto not visited by me. It didn’t take long and I stumbled over a limestone block that shows the typical lower Carnian (Julian) oxidic hardground crust. I was surprised because the geological map of this area only shows Norian strata. The weathered brown and black, oxidic cauliflowers like structures (by the point of the chisel) within the limestone are microbial reef build-ups of the sessile foraminifera Tolypammina gregaria, WENDT and Frutexites sp. They are a sign for less to zero sedimentation during a very long time. After splitting the block did not show many fossils. Only some orthocone nautiloids were visible. Then I found an ammonoid (Sphingites meriani MOJS.) and therefore I decided to take that block with me and prep out all orthocone nautiloids. Normally my focus is more on ammonoids because they are easier to insert into the Triassic timescale. During prepwork several small lower Carnian ammonoids pulled out. Prep take roughly 30 hours. Ammonoids: Arcestes periolcus MOJS., Monophyllites simonyi HAUER, Dittmarites sp., Sirenites sp., Trachyceras sp., Pompeckjites layeri Nautiloids : Syringoceras sp., Orthoceras triadicum MOJS., Orthoceras dubium(HAUER) Aulacoceras cf. inducens(BRAUN) All prepwork was done with different pneumatic chisels. The orthocone nautiloids mark the direction where the current comes from. All orthocone nautili do not lay in the same limestone horizon. Therefore several different current angles are visible.
