Thymallus Thymallus Pénzes Pér
''Thymallus'', commonly known as graylings, is a genus of freshwater ray-finned fish and the only genus within the subfamily Thymallinae of the family Salmonidae. Although all ''Thymallus'' species can be generically called graylings, without specific qualification the term "grayling" typically refers to the type species ''Thymallus thymallus'', the European grayling. Name The name of the genus ''Thymallus'' first given to grayling (''T. thymallus'') described in the 1758 edition of ''Systema Naturae'' by Swedish zoologist Carl Linnaeus originates from the faint smell of the herb thyme, which emanates from the flesh. ''Thymallus'' derives from the Greek θύμαλλος, "thyme smell". Species According to FishBase, 14 species are placed in this genus. However, views differ on their taxonomic rank. * ''Thymallus arcticus'' (Pallas, 1776) - Arctic grayling * '' Thymallus baicalensis'' Dybowski, 1874 - Baikal black grayling * '' Thymallus brevipinnis'' Svetovidov ( ru), ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Life and work Kessler was born in Damrau, Königsberg, Konigsberg, where his father was a royal forester (''oberforestmeister''). His father moved to Novgorod Governorate, where Kessler grew up.
