The study of Callovian ammonites Longaeviceras and closely related taxa from the east coast of Anabar Bay (section 109, northern Siberia) is presented. Genera and species previously unknown here, such as Rondiceras milaschevici, Pseudolongaeviceras densicostatum gen. et sp. nov., Platylongoceras holtedahli, and Pseudocadoceras laminatum, are identified. The presence of the Eboraciceras subordinarium Zone in the studied section is not confirmed. The division of genus Longaeviceras into Longoceras and Longaeviceras (including subgenus Soaniceras) is discussed. According to Cardioceras maltonense found in the upper part of the section studied, the age of the Oxfordian beds is defined more accurately.
