Binomial Utahraptor ostrommaysi · YOO-tah-RAP-tor
Early Cretaceous - 135-125 Ma
IllustrationUtahraptor fossil records in Fossil Atlas are mapped as selected modern discovery locations, with 2 source-backed records currently shown. Utah, United States, especially Cedar Mountain Formation records in the current atlas. Key mapped formations in the current dataset include Cedar Mountain. 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.
Utahraptor was a large Early Cretaceous dromaeosaur from the Cedar Mountain Formation of Utah. Fossil Atlas maps selected discovery records and connects the page to regional fossil guides.

Position of this animal’s known range across 252 million years of the Mesozoic and beyond.
135-125 million years ago
Utahraptor was far larger than Velociraptor.
Its page gives the atlas a strong US raptor route between Deinonychus and Velociraptor.
The name ties directly to Utah, making it strong for regional internal links.
Pins show selected fossil records for Utahraptor; 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.
Utahraptor is represented here by selected fossil records from utah, united states, especially cedar mountain formation records in the current atlas. 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 Cedar Mountain. Formation coverage depends on the selected dataset and may not be complete.
Yes. Use the expedition card generator to turn the Utahraptor 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.
