A variation of this analogy instead compresses Earth's 4.6 billion year-old history into a single day: While the Earth still forms at midnight, and the present day is also represented by midnight, the first life on Earth would appear at 4:00 am, dinosaurs would appear at 10:00 pm, the first flowers 10:30 pm, the first primates 11:30 pm, and ...
The work has also received positive reviews from the Horn Book Guide, School Library Journal, and Booklist, with Booklist remarking that the work was "a good group read-aloud, even for the very young." [5] [6] In 2013 School Library Journal also listed the work as one of their "Must-have Board Books for Early Childhood Collections". [7]
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.
The space rock that slammed into Earth 66 million years ago at the end of the Cretaceous Period caused a global calamity that doomed the dinosaurs and many other life forms.
