Colorado Baculite

Late Cretaceous

About Colorado Baculite

The Colorado Baculite is a cephalopod fossil dating to the Late Cretaceous. Baculite is a realistic Colorado fossil profile built around straight-shelled ammonite common in western seaway chalk and shale. In this state, success usually comes from learning Morrison outcrops, Green River beds, and uplifted marine limestones, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

“According to TroveRadar, Colorado Baculite fossils from the Late Cretaceous are found across Colorado. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
