Judith River Formation: Montana's Other Dinosaur Graveyard

The Judith River Formation of north-central Montana and southern Alberta preserves a rich Late Cretaceous (Campanian) fauna slightly older than the famous Hell Creek. It is the source of many commercial hadrosaur, ceratopsian, and tyrannosaur teeth.

Key Dinosaurs

Brachylophosaurus, Prosaurolophus, Einiosaurus, Styracosaurus, Albertaceratops, Daspletosaurus, Gorgosaurus, and numerous small theropods. Tooth material is abundant and relatively affordable compared to Hell Creek T-Rex teeth.

Legal Collecting

Same rules apply as everywhere in the US: private land only with landowner permission. Large areas of the Judith River outcrop are on private ranch land in Montana. Always demand county and landowner release.

Demand documentation before you buy

Jurassic Depot scores every listing for provenance, authenticity, and documentation. The best way to avoid fakes is to demand proof — and to know what to ask for.
