A species of Hungarella with triangular shape carapace, two posteroventral spines at RV, flattening in blade shape plus a spine at anterior border of RV, spine at AB of LV. The present assemblage doesnt include any unequivocal deep water taxa such as those discovered recently in the Carnian of Southern Turkey for example (Forel et al., 2017) or of Sichuan, South China (Forel et al., 2019b).

Similar taphonomic characteristics were also found by Pokorny (1964) and Oertli (1971) for pelitic layer associations deposited in basins with extremely rapid distal sedimentation. Diagnosis. A principal components analysis was performed using the three main characters: (1) apertural surface area index (i.e., the ratio of the apertural surface and the conch diameter), (2) buccal mass area index (i.e., the ratio between the buccal mass area and the ASarea), and (3) coiling rate of the conch.

The rock surrounding the fossil would be as old as the tropites itself, and would be from the Late Triassic Period (208 to 230 million years ago). This species is quite original and differs from all other ones by the specific characters (flattened AB and PB, and a ventral ridge along the posterior part of the VB and PB.). Phylogeny is the study of how organisms are related through evolution. 3. pre-biological changes slowly transform simple atoms and molecules into the more complex chemicals needed to produce life. 1958 Bairdia cassiana (Reuss, 1869); Styk: 171, fig.

Through time, the assemblage became more diversified as recorded by the increasing number of families (8 to 12), genera (14 to 18) and species (23 to 36). The Imerese Basin, where these sedimentary successions were deposited, was delimited by the Panormide Carbonate Platform to the west and the Trapanese Carbonate Platform to the east and south (Catalano and DArgenio, 1982; Montanari, 1987; Speranza and Minelli, 2014).

By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. A surge of recent discoveries has helped clarify some aspects of their evolution, but competing phylogenetic hypotheses raise questions about their relationships, biogeography, and fossil record quality. Holotype. Of this amount, about 800 feet belong to the Lower Triassic, about 1,000 feet to the Middle Triassic, and about . 2.

Occurrence. In this basin, therefore, occurs a transitional facies between the Panormide and Trapanese shelf facies, on the one hand, and a deep marine facies of the Neo-Tethys, on the other. In the Monte Gambanera area, the outcropping sediments are assigned to the Neo-Tethyan Mesozoic-Cenozoic complex which belongs to the so-called Imerese Succession (Lentini et al., 1987; Montanari, 1987; inter alias) or Imerese-Sicano Succession (Carrillat and Martini, 2009; Di Paolo et al., 2012).The Imerese Basin, where these sedimentary successions were deposited, was delimited by the .

This modern theory then suggests that life originated on Earth by means of a rather slow evolution of nonliving matter. (2019b; Plate 4, particularly fig. Fossilworks: Tropites subbullatus. 2020. 15. The specimens are silicified, quite well preserved and often consist of complete carapaces. 14. Type species: Simeonella brotzenorumSohn (1968). The main differences between the two species is the presence of 2 spines at PVB of RV, presence of a spine at AB of booth valves and the less distinct blade at the AB of H. siciliiensis n.sp.. We cant exclude that these differences are due to morphological variability of H. forelae n.sp. It is pointed out here that the sediments of the Mufara Basin at Monte Gambanera do not show vortex structures which were recognized in the Mufara Basin at Monte Scapello.

Morphologically, the left and right valves of Hungarella are asymmetrical contrary to those of Ogmoconcha (Kristan-Tollmann, 1977a, b; Lord, 1982): in the absence of observable central muscle scars, all Triassic occurrences of Ogmoconcha and Ogmoconchella are re-attributed to the genus Hungarella.
