内容記述タイプ | Abstract | |||||||||
内容記述 | It has been reported that two brachiopod species, namely, productid Karavankina sp. and spiriferid Choristites sp., occur from felsic tuff beds correlated to the Arakigawa Formation of the Hida Gaien belt, central Japan. Since previous studies have focused primarily on paleobiogeography and only secondarily on description, we reexamined morphological details of these fossils using clear photographic images. For each species, there only exists a ventral valve specimen but morphological features are present to determine the genera. The examined specimen of Karavankina sp. is characterized by concentric bands and rugae with numerous regularly arranged spines on the external surface of the ventral valve, while the arrangement of the long spines is altered on the marginal rugae, a trait which appears to be unique to this species. The examined Choristites sp. has a pair of dental plates (adminicula) enclosing the adductor and diductor muscle scars on the ventral floor. | |||||||||
