Anomalocaris Posted July 15, 2015 #1 Share Posted July 15, 2015 Two fossilized teeth, recovered in Nagasaki, are believed to be from the lower jaw of a ten-meter tyrannosaur that lived some 81-million-years ago. "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. 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 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.Tyrannosaurs existed in Asia and North America during the late Cretaceous Period - between 66 million years and 83 million years ago. There were numerous species of varying sizes within the tyrannosaur family, from the huge T. rex, to the more recently discovered "Pinocchio rex". http://www.bbc.com/news/blogs-news-from-elsewhere-33522144 Link to comment Share on other sites More sharing options...
