72 million years ago during the Late Cretaceous, a pair of Kamuysaurus japonicus enjoy the warm and sunny weather alongside the beach of what will someday be known as Japan. Kamuysaurus was a Japanese member of the hadrosaurid dinosaur family, the so-called “duckbills”, and its fossil remains were found in what were once marine sediments (that is, originally laid under the sea). The paper describing it suggested that it and its relatives would have preferred coastal environments in general, hence why I have chosen to depict this dinosaur alongside a beach.
