The upper part of the Portovenere Limestone (La Spezia Fm., Northern Apennines, Italy), of Late Triassic age, has been investigated in detail to define new stratigraphic elements in order to place the end-Triassic extinction event inside the successions that were visited by the participants to a field trip linked to session 253 of the 32nd IGC in Florence, 2004. New sampling of the two sections of Grotta Arpaia (Portovenere) and Muzzerone have provided good data for biostratigraphy (foraminifers, bivalves and conodonts), chemostratigraphy and lithostratigraphy-sedimentology that allow us to define the beds that contain this event.

Abstract
The upper part of the Portovenere Limestone (La Spezia Fm., Northern Apennines, Italy), of Late Triassic age, has been investigated in detail to define new stratigraphic elements in order to place the end-Triassic extinction event inside the successions that were visited by the participants to a field trip linked to session 253 of the 32nd IGC in Florence, 2004. New sampling of the two sections of Grotta Arpaia (Portovenere) and Muzzerone have provided good data for biostratigraphy (foraminifers, bivalves and conodonts), chemostratigraphy and lithostratigraphy-sedimentology that allow us to define the beds that contain this event.
