81 million-year old Tyrannasaurs teeth unearthened in Japan
Nagasaki
Two fossilised dinosaur teeth were reportedly found in southern Japan proving the existence of tyrannosaurs in the area.
The teeth were discovered in an 81 million-year-old layer of rock in Nagasaki last year, and now palaeontologists reportedly say that they're likely from the lower jaw of a 10m (33ft) long dinosaur.
According to the Fukui Prefectural Dinosaur Museum, this is the first proof that a large predator existed in the area.
The largest tooth is 8.2cm (3.2in) long, and while the second is damaged, it could have been even bigger when attached to the dinosaur, the museum says.
While the teeth were found in the same place, it's not known if they both belonged to one creature, and the specific species hasn't yet been determined.
"The findings show there was an ecosystem led by tyrannosaurs in Nagasaki, which was connected to the Asian continent by land at that time," says Kazunori Miyata, the museum's chief researcher.
