In the geological timescale, the Late Devonian epoch (from 385.3 ± 2.6 million years ago to 359.2 ± 2.5 million years ago) occurred during the Devonian period, after the end of the Givetian age. The first tetrapods appeared in the Late Devonian, circa 365 Ma.
The Late Devonian epoch is subdivided into two stages: Frasnian and Famennian, with the Late Devonian extinction event occurring at the start of the Famennian.
The earliest known trees, from the genus Wattieza, appeared in the Late Devonian around 380 Ma.[1]
