A jaw fragment of the rare ichthyosaur Tholodus is found for the first
time in the Middle Triassic deposits of the Karazin Formation (South
Primorye, Russian Far East). An analysis of the cephalopod systematics
(Acrochordiceras kiparisovae Zharnikova, A. korobkovi Zharnikova,
Acrochordiceras kiparisovae (Zharnikova), Stenopopanoceras? russkiense
sp. nov., Parasturia primorica sp. nov., and Atractites sp. indet.)
from the Tholodus-bearing unit of the Karazin Formation shows that
they correspond to the complex of the middle Anisian (Acrochordiceras
kiparisovae zone). New ammonoid species from the families
Parapopanoceratidae and turiidae are described.

NOTE: The jaw fragments are not depicted so they may be described
elsewhere. I'll see if I can find a ref.
