Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 The Mikasa City Museum in Hokkaido notes that visitors can see this fossil in its fossil exhibition hall.
- 💡 Because the genus name Nipponopelta means 'shield of Japan,' the name alone evokes an armored dinosaur.

📖 1. Overview
Nipponopelta yezoensis (genus Nipponopelta) was the first armored dinosaur (nodosaurid) from Japan to receive a formal scientific name. Its name means 'shield of Japan found in Hokkaido.'
🦴 2. Anatomy & Morphology
It belongs to Nodosauridae, a family of armored dinosaurs with prominent shoulder spines. Because the surrounding rock could not be removed any further, the inside of the skull was examined using CT scans.
🔍 3. Fossil Record & Paleoecology
Discovered in the mountains of Yubari in 1995, the fossil has been kept at the Mikasa City Museum. A paper identifying it as a nodosaurid appeared in 2005, and Hokkaido University researchers later named it as a new genus and species.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
