Tetrapod tracks from the Middle Triassic of NW Sardinia (Nurra region, Italy)
No full textWe report here on the first tetrapod tracks from the Triassic of the Nurra region (north-western Sardinia, Italy). The specimens were found on sandstone blocks used to build a fence limiting a seasonal camping, in the coastal area north of Capo Caccia promontory. Lithologic and petrographic features allowed an assignment of the track-bearing blocks to the middle-upper portion of the Anisian (Middle Triassic) Arenarie di Cala Viola (“Buntsandstein”). Footprints are attributed to the ichnotaxa Rhynchosauroides and Rotodactylus, two common ichnotaxa of late Early Triassic and Middle Triassic ichnofaunas of Europe and United States, commonly referred in the literature to neodiapsid and archosaur producers, respectively

No full textThis field trip gives a panoramic of the facies association and sedimentological-stratigraphic evolution of
Jurassic-Cretaceous depositional systems of eastern (Golfo di Orosei) and western (Nurra) Sardinia. Carbonate
deposition in western Sardinia occurred in an epeiric sea during Jurassic and Cretaceous whereas carbonates
of the eastern Sardinia figure out a complex depositional settings with intraplatformal basins facing the Alpine
Tethys from a basal transgression in the Bajocian to Berriasian. The presence of partly coeval succession allows
a comparison between these two depositional systems and highlights relation with global and regional events.
The Jurassic-Cretaceous carbonate succession of Sardinia shows similarities with coeval succession of the
Provencal-Pyrenean domain (Nurra), nevertheless differences, both in terms of facies characters and distribution
and range of stratigraphic gaps, occur between the successions of eastern Sardinia. These differences can
be ascribed to different paleogeographic and depositional settings

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
