The anticipated future event that might mark the end of the Cenozoic era is the possible onset of a new geological time period known as the Anthropocene. The Anthropocene represents a proposed epoch defined by significant influence of human activities on Earth's ecosystems and geology. The exact timing of the Anthropocene's beginning is still debated among scientists.

The epoch that humans are currently in is called the Holocene epoch. Scientists argue that the epoch we are in is actually the Anthropocene epoch, which means 'new man.'

The Cenozoic Era is the most recent of Earth's geologic eras, spanning from about 66 million years ago to the present day. It is the era of modern life, and it is characterized by the rise of mammals, birds, and flowering plants.

The era that follows the Cenozoic Era is not yet named. However, geologists have proposed a number of names for it, including the Quaternary Era, the Anthropocene Era, and the Holocene Epoch.

The Quaternary Era is the name that is currently used by the International Commission on Stratigraphy (ICS). The Quaternary Era began about 2.6 million years ago and is divided into two periods: the Pleistocene and the Holocene. The Pleistocene Epoch is known for the presence of ice ages and the extinction of many large mammals. The Holocene Epoch is the current epoch, and it began about 11,700 years ago.

The Anthropocene Era is a more recent name that has been proposed for the era that follows the Cenozoic Era. The Anthropocene Era is characterized by the profound impact that humans have had on the Earth's environment. Some geologists believe that the Anthropocene Era began as early as the 18th century, while others believe that it began more recently.

The Holocene Epoch is the most recent epoch of Earth's geologic time scale. It began about 11,700 years ago and is characterized by the retreat of the last ice age and the rise of human civilization.

It is important to note that there is no official consensus on the name of the era that follows the Cenozoic Era. The ICS is currently reviewing the proposal for the Anthropocene Era, and it is possible that a new name will be adopted in the future.
