The Paleocene or Palaeocene (the "early recent"), was a geologic epoch that lasted from approximately 65.5 to 56 million years ago. It was the first epoch of the Palaeogene period in the modern Cenozoic era.
An underwater Anomaly to the Paleocene existed in British Columbia at a shoreline, theorised to have been recurring for centuries before it was last open in 2012. A Titanoboa came through, but was ultimately lured by Mac Rendell back through the Anomaly just before it closed.
The Paleocene epoch lasted from 66 to 56 million years ago. It was a time of extinction and recovery following the K-T Mass Extinction which had marked the end of the previous period. Many plants and animals, including giant marine reptiles and non-avian dinosaurs, died off, leaving unfilled ecological niches worldwide.
