While every effort has been made to follow citation style rules, there may be some discrepancies. All the specimens are stored in the Palaeontological Museum of the University of Catania. 1990 Simeonella brotzenorumSohn (1968); Gerry et al. Ostracod associations coming from the Upper Triassic (Tropites subbullatus/Anatropites spinosus zones of the Tuvalian substage) clays and sandstones of the Mufara Formation outcropping along the west side of Monte Gambanera (Castel di Iudica, central-eastern Sicily) have been analysed for the first time.

Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). They are kind of like modern day octopus or squid but with an external shell. The deep marine ostracod fauna discovered recently in the Carnian of Southern Turkey (Forel et al., 2017) or in the South China (Forel et al., 2019a) suggests a deepening of the Neo-Tethys basin towards the more eastern areas. nov. Right lateral view of a complete carapace, PCM O FS68. 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).

All the specimens are stored in the Palaeontological Museum of the University of Catania. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

After the death of the specimens, the carapaces tend to open in a few hours (Guernet and Lethiers, 1989).

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..

The very well preserved present material enabled us to review our attribution. However, for the time being we have not enough specimens to settle this question. This species is characterized by its triangular shape, the flattening of the ventral borders and the reticulated surface. Dimensions.
