Allosaurus teeth: what buyers can actually verify
Identification evidence
Allosaurus was a large Late Jurassic theropod known from the Morrison Formation. Its teeth are laterally compressed and serrated, but isolated theropod teeth can lose diagnostic context. Ask the seller to show both cutting edges, denticles in sharp macro photographs, crown base, cross-section, wear, repairs, and the measurement method. A confident label without an identification rationale should be treated as a seller attribution, not a verified species determination.
Restoration and composite risk
Request daylight photographs before and after preparation when available, plus a diagram distinguishing original crown, root, filler, adhesive, and fabricated support. UV fluorescence can help reveal some material differences, but it is not a universal authenticity test. A restored tooth can still be collectible when the work is disclosed; the problem is an undisclosed or materially misleading representation.
Legal-origin evidence
Morrison Formation fossils occur across multiple land types. In the United States, a formation name does not establish private ownership. Commercial vertebrate material should be tied to a documented private parcel and landowner permission. Fossils from National Park Service land are protected, and the federal Paleontological Resources Preservation Act governs paleontological resources on federal land.
Do not use a generic price range
A crown fragment, repaired rooted tooth, associated jaw element, cast, and heavily reconstructed display are not comparable products. Jurassic Depot does not publish an unsupported dollar range here. Use documented, dated sales for genuinely comparable specimen class, size, condition, restoration, locality quality, and sale terms—and remember that asking prices are not completed transactions.
