An open-air paleontological exhibition Late Cretaceous Ammonites of Sakhalin opened again at the Sakhalin Regional Museum on April 30, 2019. The exhibition was first opened in September 2018. In order to preserve fossils during the winter months, in late autumn they were moved to a museum storage room. Currently, 20 large fossils are exhibited on the territory adjacent to the Museum building including the fossilized shells of extinct cephalopod mollusks ammonoids (ammonites) of the family PACHYDISCIDAE and a septarian nodule with a «tortoise shell». All fossils have been found by museum specialists during fieldwork expedition in Sakhalin, in the Late Cretaceous sediments. The approximate age of deposits containing fossils is estimated at 84–72 million years (the Campanian Stage).
