Birds are living dinosaurs
Non-avian dinosaurs disappeared at the end of the Cretaceous, but avian dinosaurs survived. In other words, pigeons, owls, penguins and crows are part of the same deeper story as Tyrannosaurus.

The Age of Dinosaurs
A multi-page English field guide with photos and art: overview, periods, an interactive timeline, a genus gallery with Wikimedia images (and offline SVG fallbacks), videos, extinction science, resources—and a playful “which dinosaur are you?” quiz.

Dinosaurs are far richer than the usual movie shorthand. These four ideas make the rest of the atlas much easier to read.
They did not all live together
The Mesozoic lasted more than 180 million years. Stegosaurus and Tyrannosaurus are often grouped together in pop culture, but they were separated by tens of millions of years.
Fossils record behavior too
Bones matter, but so do footprints, nests, eggs, bite marks, bonebeds and even microscopic wear on teeth. Paleontologists reconstruct behavior by combining many kinds of evidence rather than one “perfect” fossil.
Extinction was a global systems crash
The K–Pg event was not just “a rock hit Earth.” It involved impact ejecta, darkness, damaged food webs, climate shocks and a biosphere already influenced by late Cretaceous volcanism.
