Where have Corythosaurus fossils been found?

Corythosaurus fossil records in Fossil Atlas are mapped as selected modern discovery locations, with 11 source-backed records currently shown. Western Canada and northern interior North America, especially Dinosaur Park Formation records. Key mapped formations in the current dataset include Judith River Fm, Judith River Formation, Two Medicine Fm. These pins are fossil record locations, not a complete ancient habitat map.

This remains a specimen profile: the reconstruction, measurements, field account, and evidence sections stay intact. The fossil-map answer is surfaced here so visitors from search can orient themselves before reading the full dossier.

Field account

Corythosaurus was a crested hadrosaur from Late Cretaceous western Canada. Its selected records support the Dinosaur Park Formation cluster and help Fossil Atlas present herbivore diversity beyond horned dinosaurs.

Field notes

01

Corythosaurus had a helmet-like crest that gives it one of the clearest silhouettes among hadrosaurs.

02

Its Dinosaur Park records pair well with Centrosaurus and Gorgosaurus pages.

03

Fossil Atlas uses Corythosaurus to make the Collection 02 Canadian cluster more balanced.

Modern discovery map

Corythosaurus fossil discovery map

Pins show selected fossil records for Corythosaurus; use them as modern discovery evidence, not a complete range map. Modern fossil discovery map: pins show where selected fossil and specimen records were found today, not ancient Earth positions. What does this mean?

Corythosaurus fossil map FAQ

Where have Corythosaurus fossils been found?

Corythosaurus is represented here by selected fossil records from western canada and northern interior north america, especially dinosaur park formation records. Fossil Atlas maps those records as modern discovery locations.

Is this map where Corythosaurus lived?

No. The map shows modern fossil discovery locations from selected records. Ancient habitat and paleogeographic reconstructions are separate questions.

What formation is Corythosaurus associated with here?

The current Fossil Atlas records include Judith River Fm. Formation coverage depends on the selected dataset and may not be complete.

Can I make a Corythosaurus expedition card?

Yes. Use the expedition card generator to turn the Corythosaurus map and specimen profile into a shareable card.

Caveats

Important notes

Selected fossil records from PBDB and museum biodiversity aggregators. Source labels and confidence notes help distinguish canonical paleobiology records from specimen-media records.

Reconstruction images are labeled illustrations and do not represent fossil evidence. Size, speed, and bite-force figures are typical published estimates and remain subject to revision as new specimens are described.

Trust note

Selected source-backed records

Maps use curated PBDB, museum, and specimen-source records with visible caveats.

Trust note

Modern discovery locations

Pins show where fossils were found or reported today, not exact ancient habitat positions.

Trust note

Reconstruction is not evidence

Artwork is labeled separately from specimen photos, maps, and source records.
