The Denver Basin Collection
The Collection is a suite of approximately 25,000 specimens from Late Cretaceous, Early Paleocene, and Early Eocene strata collected at over 600 salvage sites and natural outcrops since 1991. This collection includes the 64 Ma Castle Rock Rainforest, which numbers nearly 10,000 specimens and represents the oldest known tropical rainforest, and the West Bijou collection, a suite of about 5,000 specimens that records the recovery of forests after the K-T extinction.
