Where have Deinonychus fossils been found?

Deinonychus fossil records in Fossil Atlas are mapped as selected modern discovery locations, with 17 source-backed records currently shown. North America, especially Cloverly, Antlers, and Cedar Mountain Formation records in the current atlas expansion. Key mapped formations in the current dataset include Cloverly Fm, Cloverly Formation, Arundel 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

Deinonychus was a small predatory dromaeosaur from Early Cretaceous North America. Fossil Atlas uses it to anchor new Cloverly, Antlers, and Cedar Mountain Formation pages with a fan-recognizable predator.

Field notes

01

Deinonychus helped reshape scientific thinking about dinosaur activity and bird-like traits.

02

Its sickle claw makes it one of the clearest dromaeosaur silhouettes.

03

Its records connect Cloverly, Antlers, and Cedar Mountain Formation pages.

Deinonychus fossil discovery map

Pins show selected fossil records for Deinonychus; 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?

Deinonychus fossil map FAQ

Where have Deinonychus fossils been found?

Deinonychus is represented here by selected fossil records from north america, especially cloverly, antlers, and cedar mountain formation records in the current atlas expansion. Fossil Atlas maps those records as modern discovery locations.

Is this map where Deinonychus lived?

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

What formation is Deinonychus associated with here?

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

Can I make a Deinonychus expedition card?

Yes. Use the expedition card generator to turn the Deinonychus 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.
