— Triassic through Cretaceous

Every specimen catalogued from site to case

Our holdings are documented with provenance, stratigraphic layer, and field notes. Bone-surface photographs are primary records, not interpretations.

/ Specimen record

Scale and surface detail as evidence

Each photograph documents bone wear, articulation, and preservation state. The collection spans six geologic periods, acquired directly from documented excavation sites.

First-hand acquisition

Specimens begin with the ground

Our fieldwork teams document each specimen in stratigraphic context before extraction. Provenance records are filed alongside the fossil, not added later.

Active excavation sites in Montana, Wyoming, and New Mexico feed the collection annually. The science is ongoing — not archival.

Bring a school group into the record

Guided collection visits are structured around documented specimens, not theatrical presentations. Educators receive stratigraphic context and field-note access.
