Fig. 2From: Preservation of nautilid soft parts inside and outside the conch interpreted as central nervous system, eyes, and renal concrements from the Lebanese CenomanianIsolated soft parts of the nautilid Syrionautilus libanoticus with the crustacean Corazzatocarcinus hadjoulae (mauve in E, F); PIMUZ 37707, Cenomanian, Hadjoula, Lebanon. All figures have the same scale. A Photo of the specimen taken under white light; mainly the rhyncholite is well visible. B, C Long exposure photo taken with UV light at a distance of 40 cm; note the bright bluish surfaces representing phosphatised structures; the jaw remains appear dark; note the two symmetrically arranged pairs of dark patches next to and behind the jaws. D Line drawing of the structures visible in A (light grey—even surface surrounding the specimen; pink—calcitic part of the upper jaw; dark grey—inner lamella of upper jaw; middle brown—soft part remains with a brownish appearance; orange—limonite-coloured structures; light yellow—irregular surface with patches of phosphate and possible limonite). E, F Line drawings of the structures visible in B and C (light grey—structures that appear middle greyish under UV-light; dark grey—formerly chitinous parts of the jaws that appear dark; turquoise—phosphatised structures with a strong fluorescence under UV-light; light green—phosphatised structures with a weak fluorescence under UV-light; light yellow—irregular surface with small fluorescing patches as well as dark patches, possibly limonitic; light grey—even surface that appears light grey)Back to article page
