It was found in South Dakota, in part of the Hell Creek Formation, one of the most famous and productive areas of fossil discovery in the world. The fossil record of skeletal cells has also been exploited as a proxy for genome size, as in some clades at least, there is a linear relationship between cell size and genome size.

The Fossil Record The claim that fossils document evolution is simply not true. ICR geologist Dr. John Morris and zoologist Frank Sherwin unearth the evidence of earth’s history and conclude that the fossil record is incompatible with evolution, but remarkably consistent with the biblical account of creation and the great Flood of Noah’s day.
