Nipponopelta is the first armored dinosaur ever named from Japan.1 2

Its fossils were found in marine rocks, meaning its body may have washed out to sea after death.3 1

Scientists used CT scans to see hidden bones inside the rock, like two complete teeth and part of the inner ear.1 2

Nipponopelta belonged to a group called nodosaurids, which had long spikes on their shoulders but no tail club.2 3

Its ancestors likely walked from North America to Asia across a land bridge called Beringia about 100 million years ago.3 2

Nipponopelta lived near the coast, which may have helped its relatives spread between continents.1 2

The fossil was discovered in 1995 by a local fossil hunter named Eijiro Goto along a riverbank.1 2

?Where was Nipponopelta found?

Its fossils were found in Hokkaido, Japan, along the bank of the Omakizawa River in Yūbari city.1

?Did Nipponopelta have a tail club?

No. Nipponopelta was a nodosaurid, and nodosaurids did not have a tail club. Instead, they had long spikes on their shoulders.3

?How did Nipponopelta get to Japan?

Its ancestors likely walked from North America to Asia across a land bridge called Beringia about 100 million years ago.3

?Is Nipponopelta a dinosaur?
