Description

<p>The Takisawa limestone body is embedded in the Iinoya Formation of the Chichibu Composite Belt, central Japan. The geological age of the Takisawa limestone body is ambiguous due to a paucity of index fossils. Here, we collected ten samples of the Takisawa limestone and report two fragments of conodont P1 elements. These conodonts can be identified as Primatella sp. and Kraussodontus sp., which indicate a late Carnian to early Norian age (Late Triassic). Our newly reported conodonts demonstrate that the Takisawa limestone body is Late Triassic in age.</p>
