Fossil coral. False color light micrograph of a thin cut of rock containing fossilized rugose coral. This species,now extinct,lived in tropical seas during the lower Carboniferous period around 350 million years ago. Each of the circular structures (part seen here) is the remains of a single polyp's skeleton. Corals are colonial marine organisms that live in shallow seas. They secrete an external skeleton of calcium carbonate extracted from the water. Object size: 5 mm | |
