These are thought to belong to an early branch of theropods, and reported for the first time from Ethiopia. The evidence supports a Late Triassic age for the Lower Sandstone Unit in eastern Ethiopia and also throws light on its probable depositional environment.</p> 2020-03-27T00:00:00+00:00 Copyright (c) https://riviste.unimi.it/index.php/RIPS/article/view/13197 <em>LITHOPHYLLUM GIAMMARINOI</em> SINONIMO PIÙ RECENTE Dl <em>LITHOPHYLLUM CONTII</em> DELL'OLIGOCENE LIGURE-PIEMONTESE 2020-03-31T08:41:37+00:00 PATRIZIA FRAVEGA rips@unimi.it GRAZIA VANNUCCI rips@unimi.it <p>The revision of holotypes and paratypes of<em> Lithophyllum contii</em> Mastrorilli, 1967 and <em>Lithophyllum giammarinoi</em> Mastrorilli, 1 968, coming from the Rupelian calcarenitic limestone of the "Molare Formation" (Tertiary Piedmont Basin), demonstrates that there are not enough elements to permit the distinction of two different species. So, according to priority, <em>Lp. giammarinoi</em> must be consider junior synonym of <em>Lp. contii</em>, that is here redescribed as <em>Lithophyllum contii</em> Mastrorilli sensu amplo.</p> 2020-03-27T00:00:00+00:00 Copyright (c) https://riviste.unimi.it/index.php/RIPS/article/view/13198 PALAEONTOLOGY, AGE, PALAEOENVIRONMENT AND PALAEOECOLOGY OF THE KAREWA INTERMONTANE BASIN OF KASHMIR (J&K, INDIA) 2020-03-31T08:41:36+00:00 RAJAN GAUR rips@unimi.it B.S. KOTLIA rips@unimi.it <p>A rich assemblage of vertebrate fossils, especially fish and mammals, has been recovered from the Plio—Pleistocene Karewa deposits of Kashmir (J &amp; K, India). Microtine rodents and insectivores, including some new taxa and first reports, form the most significant component of the assemblage. The Karewa vertebrate palaeontology is correlated with the magnetic polarity time scale. The Plio—Pleistocene boundary in Karewas is marked by the appearance of microtine rodents. The fossil assemblage is an admixture of high altitude and Iow altitude fauna. The fauna indicates the occurrence of a mosaic of dominant grassland and wooded grassland with some bush cover and wooded areas. A dominant lacustrine with some glacio—fluvial and aeolian environments are indicated for the Karewa sediments.</p> 2020-03-27T00:00:00+00:00 Copyright (c) https://riviste.unimi.it/index.php/RIPS/article/view/13199 NUOVI CONTRIBUTI PER L'INTERPRETAZIONE GEOLOGICA E PALEOGEOGRAFICA DELLE PREALPI GIULIE (FRIULI ORIENTALE): IL POZZO SPAN 1 2020-03-31T08:41:36+00:00 DARIO SARTORIO rips@unimi.it GIORGIO TUNIS rips@unimi.it SANDRO VENTURINI rips@unimi.it <p>This paper deals with the stratigraphy of well SPAN 1 (San Pietro al Natisone, Eastern Friuli). The stratigraphic sequence is composed by Paleocenic flysch deposits (from 69 m to 748 m), Maastrichtian resedimented carbonates (from 748 m to 940 m) and Late Jurassic reef deposits (from 940 m to 1397 m, total depth). The tectonic and sedimentary evolution of the Valle del Natisone, from the Oxfordian to the Early Eocene, is outlined.</p> 2020-03-27T00:00:00+00:00 Copyright (c) https://riviste.unimi.it/index.php/RIPS/article/view/13200 AGE, BIOZONATION AND STRATIGRAPHY OF KAZHDUMI FORMATION OF SW IRAN 2020-03-31T08:41:35+00:00 S. S. SHAKIB rips@unimi.it <p>38 species and subspecies of Foraminifera, five of which are considered to be new, are recorded from Kazhdumi Formation of SW Iran. The recognized microfossil assemblages have proved being useful for biostratigraphic zonation, age determination and correlation of the examined rocks. Two zones and three subzones are proposed. Foraminiferal faunas indicate an Albian age for the Kazhdumi Fm. Lithologic and petrographical studies showed that the formation can be divided into three members.</p> 2020-03-27T00:00:00+00:00 Copyright (c) https://riviste.unimi.it/index.php/RIPS/article/view/13201 FORAMINIFERI PLEISTOCENICI ED INTERPRETAZIONI PALEOAMBIENTALI IN UN AFFIORAMENTO DELLA SICILIA NORD-ORIENTALE (ROMETTA, MESSINA) 2020-03-31T08:41:35+00:00 DONATA VIOLANTI rips@unimi.it LAURA BONFIGLIO rips@unimi.it DOMENICA SACCÀ rips@unimi.it <p>The foraminiferal assemblages of clayey marls from Rometta (Messina, Sicily) are here quantitatively analyzed. The sediments are Early Pleistocene in age. The planktonic climatic curve shows that the deposition of marls occurred during intervals alternatively characterized by cold and warm water temperatures.</p> <p>Benthic assemblages testify a sedimentation depth of about —700 m, in the upper epibathyal zone. In order to evaluate the paleoenvironmental significance of benthic Foraminifera the following parameters were considered</p> <ol> <li>Some benthic taxa seem to be quantitatively controlled by different paleoenvironmental factors: a) by grain size of sediments as <em>Eponides turgidus</em>, <em>Gyroidinoides neosoldanii</em>, <em>G. laevigatus</em>, frequent in clayey samples or as <em>Trifarina angulosa</em>, agglutinated forms, miliolids, common In sandy samples; b) by climatic changes as <em>Bolivina pygmaea</em>, abundant in cold Intervals or as <em>Hoeglundina elegans</em> more common in warm intervals.<br>a) Faunal Density (B Foraminiferal Number), expressed by the number of benthic specimens per gram of sediment in each sample; b) Specific Diversity or Diversity Index, expressed by the number of specimens per number of species in each sample; c) Degree of Specialization, expressed by the total per centages of the five more abundant species in each sample.</li> </ol> <p>It seems possible to suggest an uplift rate of the area of 1 .4—1 .6 m/ 1000 y since the deposition of the Rometta marls.</p> 2020-03-27T00:00:00+00:00 Copyright (c)
