fossils

Dinosaur eggs reveal nesting behavior, growth, oxygen limits, shell structure, and why even giant dinosaurs did not lay impossibly huge eggs.

Fossil pigments, feathers, skin impressions, and living relatives suggest many dinosaurs were more colorful than old museum models.

A dinosaur bone does not simply survive for 66 million years — it is chemically replaced, molecule by molecule, until what you hold is stone wearing the shape of life. The odds against any given animal leaving a fossil are staggering, which is why every specimen in a museum is a triumph of improbable geology.
