三重県秩父帯阿曽カルストの石灰岩体から産出した円錐状コノドント

抄録

Three pieces of coniform conodonts were discovered in the Aso limestone body in Fuketsu Cave, Chichibu Belt, Mie Prefecture. Although the genera and species of the discovered conodonts have not been identified, they have features similar to those of Late Triassic conodonts (e.g., Zieglericonus rhaeticus Kozur and Mock). Our discovery of conodonts and further studies of the limestone may yield important information on the geological history and conditions of formation of the Aso limestone body.
