“…In general, this dermal denticles collection is clearly similar to the other euselachian morphotype dermal denticles which have already been described from the Naujoji Akmenė Formation (Lopingian) of Karpėnai quarry in the northern Lithuania [25].…”

“…Material used in this study was excavated in the November 2016 in the Kūmas quarry (56°34’56”N; 22°35’82” E), in southern Latvia. The material presented here is compared to earlier published report on the palaeoichthyofauna of the Karpėnai quarry, norther Lithuania [25]. The geographical distance between these locations is ∼70 km.…”

“…The late Permian deposits in the quarry consist of three members of Naujoji Akmenė Formation which are represented by different types of carbonate sediments from Zechstein Limestone (Ca1). The Lower Member is characterized by a 2 m thick micritic limestone, the Middle Member consists predominantly of the 8 m thick proximal tempestites and the Upper Member is a 4 m thick limestone with coated grains, where in the highest part of the unit consist of dolomitic limestone [25].…”

Moreover, various fish assemblages were widely spread in the Zechstein Basin, based on the fossil findings from Germany [21], England [22], East Greenland [23], Poland [24] and Lithuania [25].…”

The late Permian was a transformative time, which ended with one of the most significant extinction events in Earth's history. Fish assemblages are a major component of marine food webs. The macroevolution and biogeographic patterns of late Permian fish are currently insufficiently known. In this contribution, a late Permian ichthyofauna from the Kūmas quarry (southern Latvia) is described for the first time. The studied late Permian Latvian assemblage consisted of isolated chondrichthyan teeth putatively associated to ? Helodus sp., ?Acrodus sp., ? Omanoselache sp. and euselachian-type dermal denticles as well as many actinopterygian scales, numerous teeth and multiple unidentifiable microremains. This ichthyofaunal assemblage is very similar to the contemporaneous Lopingian complex of the Naujoji Akmenė formation from the Karpėnai quarry (northern Lithuania), despite the fact that the Kūmas assemblage is more diverse and abundant, in terms of fossil remains. The differences in the abundance of microremains could possibly be explained by a fresh water influx into the north-eastern Zechstein Basin margin, which probably reduced the salinity of the sea water. The new data enable a better understanding of the poorly known late Permian fish diversity from the north-eastern part of the basin.

Permian fishes and their isolated microremains are known from many localities in the Zechstein Basin. However, up to date the vertebrates have never been revealed in the southeasternmost part of this ancient sea. The new material consists of euselachian-type dermal denticles,?Listracanthus sp. dermal denticle,?Omanoselache sp. tooth, actinopterygian scales and actinopterygian teeth. Here, the detailed study of euselachian and actinopterygian remains, their stratigraphic distribution and geographical contexts is presented. Based on the qualitative analysis of teeth shapes several ecomorphotypes were described as well as the probable dietary preferences of fishes were reconstructed. These finds confirmed existence of small predators who fed on soft bodied prey as well as durophagous forms which were feeding on small shelly crustaceans or molluscs. The analysis of stratigraphic distribution of microremains, and their comparison with neighbouring sections revealed a spatially correlatable trend in increasing abundance of fishes in the more clayey parts of sections, interpreted to be positively associated with a sea level transgression event.
