A hadrosaur and Panoplosaurus
The next series in my project of reproducing Charles R. Knight paintings using the Louis Marx toys from the 1950s that used the paintings as models. The hadrosaur (duck billed dinosaur in this case an Edmontosaurus as it was reconstructed at the time). The second is the ankylosaur-clade Panoplosaurus (although the toy manufacturer called it ankylosaur).
