Binomial Dilophosaurus wetherilli · die-LOH-foh-SORE-us
Early Jurassic - 193-183 Ma
IllustrationDilophosaurus fossil records in Fossil Atlas are mapped as selected modern discovery locations, with 4 source-backed records currently shown. Southwestern North America, especially Kayenta Formation records in Arizona, with selected broader Early Jurassic context. Key mapped formations in the current dataset include Kayenta, Dharmaram. 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.
Dilophosaurus was a crested theropod from the Early Jurassic Kayenta Formation. Fossil Atlas uses the page to connect popular recognition with source-backed fossil locations and caveats.

Position of this animal’s known range across 252 million years of the Mesozoic and beyond.
193-183 million years ago
Dilophosaurus is famous for paired crests, not for the fictional frill or venom seen in movies.
Its Kayenta Formation records make a compact, strong hotspot page.
It is one of the best-known Early Jurassic predators in public searches.
Pins show selected fossil records for Dilophosaurus; 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?
Specimen evidence
No open specimen media or embeddable model assets are available in the local enrichment data yet.
Dilophosaurus is represented here by selected fossil records from southwestern north america, especially kayenta formation records in arizona, with selected broader early jurassic context. 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 Kayenta. Formation coverage depends on the selected dataset and may not be complete.
Yes. Use the expedition card generator to turn the Dilophosaurus 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.
