Tithonian
Sign in to saveIn the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series. It spans the time between 149.2 ±0.7 Ma and 143.1 ±0.6 (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous).

In the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series. It spans the time between 149.2 ±0.7 Ma and 143.1 ±0.6 (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous).
==Stratigraphic definitions== The Tithonian was introduced in scientific literature by German stratigrapher Albert Oppel in 1865. The name Tithonian is unusual in geological stage names because it is derived from Greek mythology. Tithonus was the son of Laomedon of Troy and fell in love with Eos, the Greek goddess of dawn. His name was chosen by Albert Oppel for this stratigraphical stage because the Tithonian finds itself hand in hand with the dawn of the Cretaceous.
