Quaternary and it started 16 million years ago
The Quaternary is the youngest era in the geologic time scale, which began around 2.6 million years ago and continues to the present day. It is characterized by the presence of ice ages and the evolution of humans.
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)

On the geologic time scale, an era is longer than a period. There are 12 geologic eras in total and they are composed of geologic periods. For instance, the Mesozoic era is composed of the Triassic, Jurassic and Cretaceous periods.
Cenozoic hope I helped
an era is a very long span of geologic time

Currently we are in the Cenozoic era.

The Quaternary period is the shortest era in the geologic time scale. It began about 2.6 million years ago and continues to the present day.
