Zusammenfassung: | This paper describes the conodont species found for the first time in Abrek Bay in the upper part of the Lower Triassic deposits, which are provisionally assigned through ammonoids to the
Anasibirites nevolini
zone. The study of the conodonts from these layers has made it possible to identify the assemblage composed of the species
Concervatella concervativa
(Müller),
Ellisonia triassica
Müller,
Foliella gardenae
(Staesche),
Neospathodus novaehollandiae
McTavish,
N. posterolongatus
Zhao et Orchard,
N. spitiensis
Goel, and
Novispathodus waageni
(Sweet) occurring in both the
Anasibirites nevolini
zone and the
Mesohedenstroemia bosphorensis
underlying zone, belonging to the Olenekian bottom, and also the species
Triassospathodus
aff.
homeri
(Bender) and
T. cf. symmetricus
(Orchard) that are more characteristic for the overlying ammonite zones of the Olenekian top. |
