Price context
Separate teeth, horn cores, frill pieces, skulls, and mounts before comparing value
Price bands are educational market context for common grades — not an appraisal, quote, or investment forecast.
Collecting status
U.S. private land + docs. Always confirm landowner release or export path, chain of custody, and that the specimen was not collected from forbidden public land. U.S. federal vertebrates under PRPA are not commercial inventory.

Shedding teeth are cheaper than bone. Frill / horn material needs clear land type — federal and tribal parcels cut through Hell Creek country.
How to evaluate this taxon
First identify what is actually being sold: a shed tooth, horn core, frill fragment, restored skull, or composite mount. Those are different markets. For display pieces, request a diagram distinguishing original bone, matrix, filler, and fabricated support. For isolated bone, demand multiple angles and a defensible anatomical identification.
Fake-watch for this taxon
- — Composite frills assembled from multiple animals
- — Heavy plaster rebuild sold as mostly original bone
- — Painted matrix hiding seams
Documents to demand
- — Landowner release
- — Bone vs plaster %
- — Prep map for mounts
