📖 1. Overview
Kamuysaurus japonicus (genus Kamuysaurus) is a hadrosaurid (duck-billed) dinosaur found in Hokkaido, Japan. A nearly complete skeleton was discovered in marine deposits.
🦴 2. Anatomy & Morphology
It belongs to the Edmontosaurus group (tribe Edmontosaurini), and the paper suggests that it may have had a small crest on top of its head.
🔍 3. Fossil Record & Paleoecology
Hadrosauridae was the most prosperous group of herbivorous dinosaurs in the Late Cretaceous. Growth lines in bone cross-sections show that this individual was a fully grown adult that had stopped growing.
