Comments on the validity of the taxonomic status of "Pukyongosaurus" (Dinosauria: Sauropoda).

Associated materials of euhelopodid sauropod, Pukyongosaurus millenniumi, were reported in the year 2001 from Gyeongsang Basin, South Korea. However, some of the originally proposed autapomorphies for Pukyongosaurus are present in other sauropod taxa (i.e., somphospondylus vertebrae; ventral side of cervical centrum bent with a keel, or flat; opisthocoelous centrum of dorsal vertebrae with long and deep pleurocoels; dorsally opened chevron). Others (i.e., highly and anteriorly positioned cervical neural spine; parapophyses situated on the lateroventral edge of the centrum, posterior to the articular condyle) are too poorly preserved beyond observation. Therefore, the proposed diagnostic features for Pukyongosaurus and the combinations of these characters cannot be autapomorphies, and making the taxonomic name nomen dubium. Rather, a somphospondylus vertebrae of Pukyongosaurus indicates it is an indeterminate Titanosauriformes. Moreover, its "probable clavicle" material is re-identified as a chevron based on the morphological and anatomical profiles.

Development of transparent dinosaur skull models by resin molding.

We attempted to produce the transparent dinosaur skull models by resin molding at low cost, which allows us to see the internal structure of the skull. Since multiple transparent models can be made in a short time after the production of the mold, it holds promise for expanding range of application of the transparent model in research and educational purposes. Additionally, because we can see the inside of the skull from different angles, it will promote our anatomical understanding of the dinosaur skull.
