Description

Details

Isastrea explanata fossil coral of Jurassic age, collected from Steeple Ashton, Wiltshire, UK. Isastrea is an extinct species of Scleractinian coral which existed in the Jurassic and Cretaceous periods. These reef building corals had a symbiotic relationship with photosynthetic algae and so lived in in shallow, warm, clear marine waters. This coral is an important palaeoenvironmental tool and would be a wonderful addition to any serious collectors collection. These specimens have been polished making them particularly attractive. Available in three sizes, each specimen is sold individually and is supplied in a card tray with an information label.
