Morphological convergence is an intensely studied macroevolutionary phenomenon. It refers to the morphological resemblance between phylogenetically distant taxa. Currently available methods explore evolutionary either: rely on analysis of phenotypic sister clades as compared their ancestor, fit different regimes parts tree see whether same regime explains evolution in clades, or assess deviations from congruence phylogenetic and distances. We introduce a new test for working directly with...
Abstract Despite its global impact on ecosystems, the Triassic/Jurassic boundary event had only a modest effect carbonate depositional systems of Southern Alps, whereas fundamental reorganization same palaeogeographic area took place during Sinemurian Age. This paper investigates whether or not well-documented demise platforms in Tethyan region was response to by examination carbon-isotope anomalies successions different facies that record this interval time. A chemostratigraphic transect...
Abstract. The late Paleocene orthophragminids, hitherto poorly known from the Himalayan foreland basins, are studied Lakadong Limestone in Meghalaya, northeastern India, order to establish a systematic, biostratigraphic, and paleobiogeographical framework for them eastern Tethys. In Mawmluh Quarry section (MQS) on Shillong Plateau, southeast of Tibet, orthophragminids associated with typical orbitoidiform taxa endemic Indian subcontinent, i.e., Lakadongia Matsumaru & Jauhri (= Setia...
In the Mount Messapion area (Chalkida, Greece) a continuous and expanded section of Triassic/Jurassic (T/J) limestone is exposed. This consists 710 m thick pile shallowing-upward peritidal cycles; persistence facies lack paleoenvironmental changes across T/J boundary allowed studying distribution shallow water microfossils. The placed in upper part defined by correspondence with (i) last occurrence Triasina hantkeni , (ii) abrupt disappearance megalodontid faunas (iii) presence Early...
Siphovalvulina is among the first foraminifera that appear on carbonate platforms of Lower Jurassic, forming a conspicuous element low-diversity assemblages prior to recovery after end-Triassic biotic crisis. The high morphologic variability species this genus usually not documented, which makes determination difficult and subjective. We demonstrate in five morphotypes Sinemurian Pliensbachian rocks from Dinarides Southern Apennines. Due different interpretation its architecture, an...
In late Paleocene-Eocene times, in the Tethyan area, shallowest and most restricted carbonates deposited between intertidal zone lower limit of upper photic zones are characterized by Spirolina -dominated facies. This extremely shallow-water carbonate facies is recorded from Cenomanian to Miocene realm with similar sedimentological characters spiroliniform epiphytic taxa. All these taxa can be considered reflect some kind vicariance through time. Southern Italy this peculiar represented...
Parachaetetes asvapatii is a very common algal species in the Palaeogene deposits of Tethyan realm and has been considered as member heterogeneous family Solenoporaceae. This attribution exclusively based on features vegetative tissue, since no reproductive structures have ever recovered. However, detailed analysis Late Cretaceous–Eocene material from Turkey revealed nemathecia‐like one specimen attributable to P. . These nemathecia are small wart‐like protruding thallus surface that formed...
New observations on abundant material from the type locality of Petrascula iberica (DRAGASTAN & TRAPPE) GRANIER et al. 2003, reveal presence a reproductive structure (ampulla) located inner-middle part each primary lateral. This fact suggests new interpretation alga and establishment genus: Granieria BARATTOLO ROMANO, n. gen. Also, taxonomic status other club-shaped specimens both High Middle Atlas Morocco Central Apennines Italy is reviewed.
Polyphysacean algal fertile caps from the Sarmatian near Suceava (NE Romania) are here described as a new species, Acetabularia moldavica, ascribed to extant genus due presence of both inferior and superior coronae.Gametangia preserved closely packed within gametophore.The gametangium wall is strongly mineralized SEM observations show acicular aragonite crystals arranged perpendicularly surface.The occurrence cyst walls distinguishes species other three Acetabularia, namely miocaenica,...
Abstract The genus Falsolikanella , introduced by Granier (1987), was based on the basal Cretaceous species Likanella campanensis Azéma and Jaffrezo (1972) assigned to tribe Diploporeae (Pia, 1920) emend. Güvenc, 1979 within green alga order Dasycladales. Later, other were . Sections of type specimens are reviewed. They show that in this species, arrangement laterals is not metaspondyl, but typical Actinoporella (Gümbel Alth, 1882) emend Conrad, Praturlon, Radoičić, 1974, with coronae...
