Single celled dinosaurs are fossilised single celled organisms named Nummulites which have provided evidence that large size in living organisms is related to long life. Geologists at Oxford University (UK) studied fossilised shells of nummulites found in England and estimated that they had life span of approximately five years. Nummulite fossils are also found in the limestone of the pyramids of Egypt but they are much larger, about 2mm, a gigantic size for a unicellular organism. "These were the dinosaurs of the unicellular world," said Oxford geologist Martin Brasier in New Scientist, 7 August 1999, p17. His explanation of the large size is that they lived longer (about a hundred years).

Editorial Comment: We are not surprised by the link between long life and large size. Genesis says that prior to Noah’s Flood, man lived for nearly 1,000 years in a climate that had no extremes of winter or summer. Such a better world would have also benefitted other life forms as well. (Ref. Nummulites, lifespan, size)
