Oldest hairy microbe fossils discovered
[ Sun, 27 Nov 2011 17:55:22 GMT ]

This microscopic fossil closely resembles a modern tintinnid, a single-celled organism that is a type of plankton. Fossil ciliates including this one were recently identified in a deposit in Mongolia, and they are more than 100 million years older than the previously known fossils of this type.Ancient rock deposits, laid down between two massive ice ages, reveal the oldest known fossils for two types of single-celled creatures: Tube-shelled foraminifera and hairy, vase-shape ciliates.
