Cenozoic period.

Periods. Just as eons are subdivided into eras, eras are subdivided into units of time called periods. The most well known of all geological periods is the Jurassic period of the Mesozoic era (the movie Jurassic Park, of course, has something to do with that). The Paleozoic era is divided into six periods.

This specimen shows gastropod shells which have accumulated in muddy sediment, and then been 'current aligned', i.e., the movement of the water has turned them so they face the same direction. This specimen comes from the Cenozoic of New Zealand. Image shown in both plan and cross-sectional views. See also specimens 14 and 21.Gastropods During the Cenozoic Era Evolution of marine gastropods, especially caenogastropods, in the Cenozoic was in many ways a continuation of trends established in the Late Cretaceous. Neogastropods and cerithioids diversified rapidly in the Paleogene, with many modern genera, including Conus (cone snails), originating during this interval. The Cenozoic, from the Greek for “recent life,” began c. 65.5 million years ago and is divided into three periods: the Paleogene (65.5–23 million years ago), Neogene (23–2.6 …

The Cenozoic Era (66 million years ago [MYA] through today) is the "Age of Mammals." North America's characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.

The K/Pg extinction marked the end of the Mesozoic Era and the beginning of the Cenozoic Era, the Era that we live in today.
