Late Cretaceous - 76-73 Ma
AI reconstructionParasaurolophus fossil records in Fossil Atlas are mapped as selected modern discovery locations, with 18 source-backed records currently shown. Western North America, including selected records from Kirtland, Fruitland, Dinosaur Park, and related Late Cretaceous units. Key mapped formations in the current dataset include Kirtland Sh, Kirtland Formation, Fruitland Formation. 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.
Parasaurolophus was a crested hadrosaur from Late Cretaceous North America. Fossil Atlas maps selected records from formations including Kirtland, Fruitland, and Dinosaur Park while keeping the caveat that pins show modern discovery locations.

Parasaurolophus is famous for its long hollow crest, often interpreted as part of a sound-producing system.
Its records help Fossil Atlas build a richer mid-to-late Cretaceous North America cluster.
The crest makes it one of the most visually recognizable hadrosaurs.
Pins show selected fossil records for Parasaurolophus; 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?

Parasaurolophus is represented here by selected fossil records from western north america, including selected records from kirtland, fruitland, dinosaur park, and related late cretaceous units. Fossil Atlas maps those records as modern discovery locations.
No. The map shows modern fossil discovery locations from selected records. Ancient habitat and paleogeographic reconstructions are separate questions.
The current Fossil Atlas records include Kirtland Sh. Formation coverage depends on the selected dataset and may not be complete.
Yes. Use the expedition card generator to turn the Parasaurolophus map and specimen profile into a shareable card.
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.
Maps use curated PBDB, museum, and specimen-source records with visible caveats.
Pins show where fossils were found or reported today, not exact ancient habitat positions.
Artwork is labeled separately from specimen photos, maps, and source records.
