WALHALLA, N.D. (AP) -- State and local officials are hosting a fossil dig at the Pembina River Gorge in northeastern North Dakota this week.
Fossils as old as 80 million years were recently found in the area, including those of mosasaurs, giant sea lizards that were fearsome predators.
Fossils of sharks and fish also have been found.
The dig is being hosted by the state Geological Survey and state Parks and Recreation Department, along with the Walhalla Economic Development Corp.
Members of the public can participate for a fee, if there are any slots available.
