Abstract

We describe isolated maxillary tooth and cervical vertebra from the Upper Cretaceous Ashizawa Formation of the Futaba Group in Fukushima Prefecture, Japan, which belong to a hadrosauroid dinosaur. The occurrence of these materials in the shallow-marine sediments suggests the habitat of this dinosaur in the coastal region, as discussed in previous studies.
