It included a Velociraptor attacking a Protoceratops, [172] providing evidence that dinosaurs did indeed attack each other. [173] Additional evidence for attacking live prey is the partially healed tail of an Edmontosaurus, a hadrosaurid dinosaur; the tail is damaged in such a way that shows the animal was bitten by a tyrannosaur but survived ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.

[2] He became interested in dinosaurs as a teenager, not a young child like many palaeontologists, so he read adult popular science books, which he described as a "gateway into science". He wanted to write an up-to-date book on "the whole evolutionary story of dinosaurs" that would fill that niche and cover new discoveries, which hadn't been ...
