The Anisian macroflora from the Northern Dolomites (Kühwiesenkopf / Monte Prà della Vacca, Braies): a first report

The knowledge of Triassic macroflora from the Dolomites mostly concerns the Ladinian, while literature data on Anisian plants are scarce. This gap is filled by the discovery, reported here, of a rich plant deposit from Kuhwiesenkopf / Monte Pra della Vacca (Prags/Braies Dolomites). The fossils occur in a horizon, about 1 m thick, from the lower part of the Dont Formation, a basinal unit mostly constituted by hemipelagic, terrigenous-carbonatic sediments of Pelsonian - Illyrian age. The stratigrafic interval with the plant horizon is Pelsonian in age. A preliminary systematic analysis of the numerous and well preserved specimens has allowed the identification of at least 17 genera. The taxa belong primarily to the Pteridophyta ( Anomopteris, Neuropteridium, Cladophlebis, Crematopteris, ? Marattiopsis ), subordinately to the Cycadophyta ( Bjuvia, Taeniopteris, Dioonitocarpidium, Pterophyllum / Nilssonia ). Coniferophyta are represented by Voltzia , ? Voltzia and Albertia ; the latter genus is recorded herein for the first time in the Middle Triassic of the Dolomites. Besides, two Lycophyta genera (? Isoetites , Lycophyta new taxon), three Pteridospermae genera (? Sagenopteris , Scytophyllum and Peltaspermum ), and one Sphenophyta genus ( Equisetites ) have also been recognized.

FIRST RECORD OF EVERTICYCLAMMINA REDMOND 1964 (E. PRAEVIRGULIANA N. SP.; FORAMINIFERA) FROM THE EARLY JURASSIC OF THE VENETIAN PREALPS (CALCARI GRIGI, TRENTO PLATFORM, NORTHERN ITALY)

The rich fossil content of the Lower Jurassic carbonate successions of the Trento Platform (northeastern Italy) have been studied since the beginning of the nineteenth century. This detailed study on several stratigraphic sections cropping out in this area, all spanning the Liassic Rotzo Member (Calcari Grigi formation, Venetian Prealps), provides us new biostratigraphic data about the genus Everticyclammina Redmond 1964. A new species of Everticyclammina, E. praevirguliana n. sp., is formally described from the Calcari Grigi, where it occurs in levels attributed to the late Sinemurian to Domerian age. Everticyclammina praevirguliana n. sp. thus becomes the first representative of the genus in the Early Jurassic; this record consequently enables the stratigraphic distribution of the genus to be lowered to the Liassic. Hence the plexus of Everticyclammina evolving communities now bridges the Liassic (late Sinemurian) to Early Cretaceous (Aptian) interval.
