WebThe Tertiary was an official geological period, but it is no longer used. It included the first part of the Cainozoic. This is now divided into the Palaeogene and the Neogene . The previous use of the term "Tertiary" explains why the last period of the Cainozoic is called the Quarternary. There was a big debate about that. The continents in the Neogene were very close to their current positions. The Isthmus of Panama formed, connecting North and South America. The Indian subcontinent continued to collide with Asia, forming the Himalayas. Sea levels fell, creating land bridges between Africa and Eurasia and between Eurasia and North America.
Tertiary Period - Epochs, Climate, Plants, Animals and Major Events
WebThe Neogene Period is the shortest period of the Cenozoic Era. It is divided into only two epochs - the Miocene and Pliocene epochs. In the Miocene epoch grass spread across the globe and new species evolved. The apes in this epoch evolved into 30 new species. It is estimated that 95% of the seed plants evolved during this epoch. WebNeogene Period The Neogene Period comprises the interval of 23–2.6 mya, including the Miocene and Pliocene epochs. This entire interval is characterized by gradually declining atmospheric CO 2 levels and the cooling of global temperatures ( Fig. 7, upper panel). Some interesting climatic reversals took place during the Miocene. head start catawba county nc
