Abstract
The Upper Triassic (Carnian) Mufara Formation outcrops in several localities in Western Sicily. It consists of deep-water marl-limestone alternations with intercalations of calcareous turbidites and debrites. Shallow water carbonates of both reef and lagoonal facies are abundant constituents of the elastic intercalations. In channel-filling carbonate debrites outcropping at Cozzo Paparina, near Altofonte, SW of Palermo, the elements exhibit different facies types as well as different age. The paleontology and facies of carbonates belonging to the reef facies of Carnian age, were described by Senowbari-Daryan and Abate (1986). The lagoonal facies is represented by two distinct facies types: "Cayeuxia" bindstone and dasycladacean grainstone. Diplopora annulatissima Pia is the most abundant species in the dasycladacean association of this grainstone facies, followed by Teutloporella peniculiformis Ott and a further dasycladacean species tentatively assigned to Physoporella lotharingica (Benecke). The problematic organism (possibly a dasycladacean alga) Zornia obscura (= "Problematikum 1" Zorn 1971), is newly described. The stratigraphic age of the dasycladacean-bearing boulders is discussed and an Anisian? - Ladinian age is suggested. The source area of dasycladacean grainstone was an unidentified Middle Triassic carbonate platform. This represents the first evidence for an Anisian? - Ladinian carbonate platform in Sicily.
