Download scientific diagram | Diversity of ostracod families from the Tropites subbullatus/ Anatropites spinosus zones represented by number of genera (A) and species (B) in the samples of Mount . Occurrence. The Tropites subbullatus is from the Triassic period, the time following one of history's most significant mass extinction events that left a mere tenth of the planet's species intact. This was a sea creature with a snail shell appearance because it's a shell with a spiral shape. As they are stratigraphicaly very close and the number of specimens is quite low, we consider here the ostracod assemblages of both samples in all. The palaeoecological interpretation of the sedimentary facies of the Mufara Formation is extremely difficult due to the absence of intact outcrops. 6. Occurrence. Occurrence. Tropites, genus of extinct cephalopods (animals similar to the modern squid and octopus but with an external shell) found as fossils in marine rocks of the Late Triassic Period (from 230 to 208 million years ago). sp. has been analysed since the beginning of the nineteenth century by Calcara (1840, 1845), Nelli (1899a, b) and subsequently by Gemmellaro (1904), Scalia (1907a, b, 1909, 19101914), Maugeri Patan (1934) and Lentini (1974).
