Succession of selected bioevents in the continental Permian of the Southern Alps (Italy): improvements in intrabasinal and interregional correlations

The Permo-Triassic Tetrapod Faunal Diversity in the Italian Southern Alps

“…Recent reviews have been published by Conti et al (1997), Conti et al (1999), Conti et al (2000), , Avanzini & Mietto (2008). Here we provide an updated overview on these studies focusing on the contribution that tetrapod ichnology can give to the debates concerning the large scale patterns of extinction and subsequent recovery on lands near the PT boundary (Benton & Twitchett, 2003;Twitchett et al, 2001;Retallack et al, 2006;Sheldon & Chakrabarti, 2010).…”

“…3). Traditionally, these discrete associations have been considered 'Faunal Units' (FU) (Conti et al, 1997;Conti et al, 1999;Conti et al, 2000;Ronchi et al, 2005). In the present study: i) no vertical differences within a single bin have been considered even though some are well known; and, ii) only species-level determinations have been considered except where a genus or a higher-level taxon is represented by an undetermined species only (e.g., Procolophonichnium isp.…”

“…Data have been recorded in the Collio basin (Geinitz, 1869;Curioni, 1870;Cassinis, 1966;Berruti, 1969;Ceoloni et al, 1987;Conti et al, 1991) and from sediments cropping out in other localities of the Orobic basin (Gümbel, 1880;Dozy, 1935;Casati, 1969;Casati & Forcella, 1988;Nicosia et al, 2000;Santi, 2003Santi, , 2005Santi & Krieger, 2001) and in the Tregiovo and Luco basins (Conti et al, 1997;. The ichnoassociation includes the following ichnospecies (after Conti et al, 1997;Conti et al, 2000, updated) (Fig. 1).…”

“…The continental succession has been dated by means of palynomorphs and tetrapod footprints (e.g. Conti et al, 1997;Cassinis and Perotti, 2007), whose calibration with standard marine biozones is generally difficult, whereas the Bellerophon Fm carbonates from marginal and restricted marine environments (e.g. marly dolomites and dolomitic limestone) yield rare eurytopic foraminifers and calcareous algae with low chronostratigraphic value.…”
