Stratigraphy
Formation:Zorzino Limestone
Stratigraphic resolution:formation
Stratigraphy comments: material from a sequence of 3 levels, each bearing bones. Unclear which fossils are from which layers. Uppermost part of the Zorzino Limestones (Calcare di Zorzino) of latest Alaunian age (dated by palynomorphs)
Lithology and environment
Primary lithology:dolomitic argillaceous,carbonaceous "limestone"
Secondary lithology: marl
Includes fossils?Y
Lithology description: heterotopic limestone, micritic, with bituminous facies, argillaceous layers, dolomitic layers, and neraster marls.
Environment:shallow subtidal indet.
Geology comments: carbonate platform with quiet sedimentation, eventually probably stagnant, shallower, and anoxic at depth. Cyclic carbonate sedimentation evident, as well as supratidal erosion. Sequence from intertidal transgressive, to subtidal, to intertidal regressive phases.
Taphonomy
Modes of preservation:body,adpression,soft parts
Lagerst�tten type:conservation
Size of fossils:macrofossils,mesofossils
Preservation of anatomical detail:excellent
Abundance in sediment:common
Temporal resolution:snapshot
Spatial resolution:allochthonous
Collection methods and comments
Collection methods:selective quarrying,field collection
Reason for describing collection:taxonomic analysis
Collection dates:1978-1985
Collection method comments: Nosotti 1986 reports a single Psephoderma alpinum tooth (ID no. V467) from "Endenna (Zogno, Bergamo), Calcare di Zorzino, Norico superiore" in the collections of the Museo Civico di Storia Naturale di Milano.
