Fissure 4, Quarry 20, Monte Tuttavista, Orosei, Sardinia (Pleistocene to of Italy)

Also known as IV 20

Where: Sardinia, Italy (40.4° N, 9.7° E: paleocoordinates 40.4° N, 9.5° E)

• coordinate based on nearby landmark

When: Middle Pleistocene to Middle Pleistocene (0.8 - 0.0 Ma)

• Middle-Late Pleistocene. A new faunal complex subdivided into primitive (earlier) 'Praemegaceros-Tyrrhenicola' complex and a later one. This is the earlier and comprises the following fissures - XI canide, XI dic.2001, XI Mar 2002, XI 3, XI rondone. IX Prolagus, XI 3, IV 5 and IV 20 appear to form a slightly earlier subgroup.

Environment/lithology: fissure fill

• Monte Tuttavista is 836m a.s.l. and is formed of Mesozoic limestones. Dissolution has formed a network of fissures, which are mainly narrow and coincident with fracture lineaments.
• Fissures contain various detrital sediments ranging from fossil breccias to dark clays. Different depositional events can be distinguished in some of the larger fissures/cavities.

Size classes: macrofossils, mesofossils

Collection methods: bulk, sieve,

• Specimens are held at the Operating Office of the Soprintendenza per Beni Archeologici in Nuoro and in the Archaeological Museum of Nuoro.

•Localities found in 1995, this paper (ref. 13691) reports on work from 1996-2003.
