E-mail: *[email protected] Abstract In this paper we describe four new fossil associations of “reef” and “reef”-like environments of the St. Cassian Formation (Ladinian-Carnian, Dolomites, NE Italy), based on thirty thin sections from 10 “Cipit boulders” olistoliths, which slided from the Cassian platform into coeval basin sediments. The fossil associations were determined by means of microfacies analysis using point-counting and visual estimation, as well as with aid of statistical methods, based on all fractions with a biotic significance (biomorpha and microbialites). Cluster Analyses in Q-Mode were performed, coupling three algorithms and two indices. In all samples, the main components of the framework are microbialite (average of 75%), and macrofossils (average of 20%), whereas cements and allochtonous components, such as allomicrite, do not represent a significant fraction. Based on both microbialite and fossil content, Chaetetid–microencruster Association, Microbialite–microencruster Association, Dual-type Microbialite Association and Microbialite–Terebella Association, were differentiated. -

Pre-Race Press Release
s July 2014 Maratona dles Dolomites – Enel 2014 PRE-RACE PRESS RELEASE ADDRESS BY THE PRESIDENT MICHIL COSTA Life is made up of moments which are not experienced necessarily in sequence and which do not represent a slice of time. Moments have their own existence and consistency. You may be able to spend here many beautiful moments, important moments, moments of life. “Giulan” for your contribution in making the marathon important, “Giulan” for being here. 9,000 CYCLISTS FROM ALL OVER THE WORLD FOR THE 28TH EDITION. (Alta Badia – Alto Adige). On Sunday 6th July, the departure is fixed for 6.30 a.m. from La Villa. The arrival is always in Corvara for the most famous long distance cycling race in Europe. As every year, the closed number guarantees the race runs perfectly for the over 9,000 cyclists drawn, representing 58 nationalities, to meet the over 32,600 entry applications, which arrived in a few days in October 2013, the opening date for entries. The legendary Campolongo, Sella, Pordoi, Gardena, Giau, Falzarego and Valparola Passes, completely closed to traffic, will allow them to tackle the three race routes: Long 138 km and a climb of 4230 metres, Medium of 106 km and a climb of 3130 metres and Sella Ronda of 55 km and a climb of 1780 metres. THE WALL OF THE CAT – THE GREAT NEW FEATURE OF THE 28TH MARATONA DLES DOLOMITES-ENEL 2014! The great innovation for all the cyclists on the medium route (at the 101st kilometre) and on the long route (at the 133rd km). -

2021 Giro Virtuale Ride Report 210602
Giro d’Italia Virtuale 2021 had not given much thought to a 2021 Giro d’Italia Virtuale until I was contacted out of the blue via LinkedIn the week before the real Giro I started. “Are you the Pike Talbert who created the Fulgaz Giro d'Italia Virtuale last year at https://fulgaz.com/my-giro-ditalia-virtuale-pike- talbert?” his note began. “If so, I'm wondering if you were going to curate a version 2.0 for the 2021 Giro?” That was all the inspiration I needed! A week later: Tahdah! An initial draft was complete: 21 stages utilising 20 FulGaz rides, 14 of which were new this year—either recently released by FulGaz, or recently discovered by moi. Several iterations later the final version was complete. The Table below provides a comparative Summary. A couple of background comments are worth highlighting: • My Giro last year was mostly about climbing as many of the famous and iconic mountain passes as possible. I have discovered the hard way that this is actually boring (not to mention painful). It turns out that flatter, rolling stages usually contain better scenery—a “smell the roses” approach that favours vistas and seeing more of Italy’s natural beauty over elevation gain and degree of difficulty. Thus, I have inserted more flatter and rolling stages. • Most of the rides I have eliminated in favour of the new ones are longer climbs (i.e., greater than 90 minutes based on videographer time and 3 of the 4 Stelvio-related ascents). It is for this reason that the total time is nearly an hour less than last year. -

Trace Fossil Assemblages in a Middle Triassic Mixed Siliciclastic- Carbonate Marginal Marine Depositional System, British Columbia
Palaeogeography, Palaeoclimatology, Palaeoecology 166 (2001) 249–276 www.elsevier.nl/locate/palaeo Trace fossil assemblages in a Middle Triassic mixed siliciclastic- carbonate marginal marine depositional system, British Columbia J.-P.

Pembertonc aGeological Survey of Canada (Calgary), 3303, 33rd Street N.W., Calgary, Alta., Canada T2L 2A7 bDepartment of Geology, University of New Brunswick, Fredericton, NB, Canada E3B 5A3 cIchnology Research Group, Department of Earth and Atmospheric Sciences, University of Alberta, Edmonton, Alta., Canada T6G 2E3 Received 20 July 1999; accepted for publication 1 August 2000 Abstract A diverse ichnofossil assemblage characterizes the mixed siliciclastic-carbonate marginal marine succession of the upper Liard Formation (Middle Triassic), Williston Lake, northeastern British Columbia. Sedimentary facies within this succession consist of five recurring facies associations: FA1 (upper shoreface/foreshore); FA2 (washover fan/lagoon); FA3 (intertidal flat); FA4 (supratidal sabkha) and FA5 (aeolian dune). Shoreface/foreshore sediments (FA1) accumulated on a storm-dominated, prograding barrier island coast and are characterized by a low-diversity Skolithos assemblage (Diplocraterion, Ophiomorpha, Palaeophycus, Planolites, Skolithos and Thalassinoides). Washover fan/lagoonal sediments (FA2) are dominated by trophic generalists. (Cylindrichnus, Gyrochorte, Palaeophycus, Planolites, Skolithos, Trichichnus and an unusual type of bivalve resting trace), consistent with deposition in a setting subject to periodic salinity and oxygenation stresses. Intertidal flat deposits (FA3) are characterized by a diverse mixture of dwelling, feeding, and crawling forms (Arenicolites, Cylindrichnus, Diplo- craterion, Laevicyclus, Lingulichnus, Lockeia, Palaeophycus, Planolites, Rhizocorallium, Siphonichnus, Skolithos, Teichich- nus, Taenidium, and Thalassinoides, reflecting the presence of adequate food resources in both the substrate and in the water column. -
Dinosaur Diversification Linked with the Carnian Pluvial Episode
ARTICLE DOI: 10.1038/s41467-018-03996-1 OPEN Dinosaur diversification linked with the Carnian Pluvial Episode Massimo Bernardi 1,2, Piero Gianolla 3, Fabio Massimo Petti 1,4, Paolo Mietto5 & Michael J. Benton 2 Dinosaurs diversified in two steps during the Triassic. They originated about 245 Ma, during the recovery from the Permian-Triassic mass extinction, and then remained insignificant until they exploded in diversity and ecological importance during the Late Triassic. Hitherto, this 1234567890():,; Late Triassic explosion was poorly constrained and poorly dated. Here we provide evidence that it followed the Carnian Pluvial Episode (CPE), dated to 234–232 Ma, a time when climates switched from arid to humid and back to arid again. Our evidence comes from a combined analysis of skeletal evidence and footprint occurrences, and especially from the exquisitely dated ichnofaunas of the Italian Dolomites. These provide evidence of tetrapod faunal compositions through the Carnian and Norian, and show that dinosaur footprints appear exactly at the time of the CPE. We argue then that dinosaurs diversified explosively in the mid Carnian, at a time of major climate and floral change and the extinction of key herbivores, which the dinosaurs opportunistically replaced. 1 MUSE—Museo delle Scienze, Corso del Lavoro e della Scienza 3, 38122 Trento, Italy. 2 School of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK. 3 Dipartimento di Fisica e Scienze della Terra, Università di Ferrara, via Saragat 1, 44100 Ferrara, Italy. 4 PaleoFactory, Dipartimento di Scienze della Terra, Sapienza Università di Roma, Piazzale Aldo Moro, 5, 00185 Rome, Italy. 5 Dipartimento di Geoscienze, Universitàdegli studi di Padova, via Gradenigo 6, I-35131 Padova, Italy. -
