Fossil Atlas answer
Where were Pachycephalosaurus fossils found?
Pachycephalosaurus fossils in Fossil Atlas are represented by 12 selected modern discovery records. Known from latest Cretaceous western North America, especially Hell Creek and Lance-style northern Great Plains records. These are fossil discovery locations, not a complete ancient habitat map.

Misconception
Found does not mean lived exactly there
Fossil sites are modern discovery locations. Rock movement, erosion, collection history, and incomplete datasets all shape the map.

FAQ
Common questions about Pachycephalosaurus fossil locations
Where is Pachycephalosaurus best known from?
Pachycephalosaurus is best represented here by records tied to Hell Creek and related latest-Cretaceous units. Fossil Atlas maps selected source-backed records rather than every published specimen.
Is the Pachycephalosaurus map an ancient habitat map?
No. The map shows modern discovery locations where fossils were found or reported today. Ancient habitat and paleogeography are separate reconstructions.
Can I make a Pachycephalosaurus expedition card?
Yes. The Pachycephalosaurus profile feeds the expedition card generator with the animal image, selected records, stats, and visible evidence caveats.
