Thirty years after the state of Nebraska purchased the Ashfall Fossil Beds site, ancient discoveries continue to be made.
Superintendent Rick Otto says they just opened for another season.
He says interns are being trained on excavation techniques, so they can pick up where work ended last year.

Otto says the students will finish excavating fossils uncovered last year and then move a few feet over.

The fossils of mammals, turtles, and birds have been found at the 360 acre site in northeast Nebraska. The site is four miles east, and six miles north of Orchard Nebraska.
