Abstract

Unknown fossil collections from the Bakony Mts, collected by J. Nosky Jnr. during his mapping activity in the 1940s and 1950s were found in the storage facility of the Hungarian Geological Institute in the 2010s. In these materials from the Upper Bajocian (Middle Jurassic) from the Som-hegy of Bakonybél (formerly known as part of Pénzeskút) some specimens were determined by Nosky in 1959 as ‘Canaliphylloceras’ nov. gen. nov. sp.’ However, Nosky never published these faunal studies, and his designations have only been preserved as notes written on the labels of the specimens. The same form identified by Nosky was also identified as a new species from Gyenespuszta, another Middle Jurassic locality in the Bakony Mountains, in 1980 with the name Adabofoloceras hajagensen. sp. Galácz, 1980. The name suggested by Noszky is invalid; however, his distinction of these forms as representing an individual taxon is justified. This contribution is a tribute to Jenő Nosky, a great researcher of the Hungarian Jurassic by making his faunistic study known and showing his original specimens.
