1.Paleomagnetic measurements demonstrate that the Jijiagou section which is the stratotype one of Baode Stage of the Neogene in China records 12 normal and 11 reversed polarity zones.
2.The basin tectonic model: it is intermont basin during late Jurassic to early Cretaceous, developed into faulted-lacustrine basin in Eogene, and evolved into depression in Neogene and Quaternary.
1.And the family seems to have diversified a lot in the middle Neogene Period, around 14 million years ago, which is also when we start seeing a lot of its fossils.
2.In some books, too, you will find the tertiary and quaternary taken out and replaced by periods of different lengths called the Palaeogene and Neogene.
