Terreneuvian
The Terreneuvian is a proposed geological period within the Cambrian Period, part of the Paleozoic Era. It is one of several subdivisions that have been suggested to refine the traditional Cambrian timescale, which currently consists of three stages: the Terreneuvian, Serpukhovian, and Furongian. The name "Terreneuvian" derives from the Latin words *terra* (meaning "earth") and *neovius* (meaning "new"), reflecting its position as the earliest division of the Cambrian.
The Terreneuvian spans from the beginning of the Cambrian Period, approximately 541 million years ago, until
The Terreneuvian is further divided into two stages: the Fortunian and the Dapingian. The Fortunian, the earliest
Geologically, the Terreneuvian corresponds to the deposition of sedimentary rocks such as the Tommotian and Atdabanian
