The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. The somewhat confusing terminology and disagreement amongst geologists on where to draw what hierarchical boundaries is due to the comparatively fine divisibility of time units as time approaches the present, and due to geological preservation that causes the youngest sedimentary geological record to be preserved over a much larger area and to reflect many more environments than the older geological record. It ended around 2.4 million years ago at the start of the Quaternary Period. The continents in the Neogene were very close to their current positions.
