A great confusion exists in the systematics of Late PermianTriassic Healdiidae genera HungarellaOgmoconchaOgmoconchella. 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.

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). Remarks. They are carnivores. Biological evolution and phylogeny: Evolution explains how new species of organisms arise or how existing organisms adapt to new conditions over time. : fig.

The Triassic forms belong to Hungarellinae Kristan-Tollmann (1971) and Liassic ones to the subfamily Pseudohealdiinae Grndel (1964) (Kristan-Tollmann, 1971). Three species of Acratia from the Carnian of Karavanke Mountains, Solvenia, are figured in Forel et al. This unit, outcropping in the southern slopes of the mount, mainly consists of dark grey pelites, which locally contain rare ammonites, with rare interbeds of fossiliferous calcarenites and fibrous calcite with Halobia spp. Dimensions.

In contrast, most ammonoids possessed, at comparable conch sizes, much smaller buccal apparatuses and hyponomes, suggesting a more passive life history with reduced mobility potential and reduced capacities for larger prey items. 28, figs. 5.

Tropites subbullatus (Hauer, Reference Hauer 1849): Adult modifications play an important role in Triassic ammonoids, and hence this species was chosen as an example. In 2013, Crasquin and Forel mentioned the last occurrence of neritic Acratia in the Spathian and of deep marine Acratia in the Anisian (Crasquin-Soleau and Grdinaru, 1996). 7, 8, 10.
