Ages: Further Divided

Last time, we were venturing through the eons, eras, and epochs. But today, we’ll be venturing into the zenith of geological times: ages.

If I mention the time of T. Rex in basic forms, I would be saying Late Cretaceous, Mesozoic Era in the Phanerozoic Eon. But here’s the catch. Saying just Late Cretaceous would mean that it lived alongside much older genera such as Spinosaurus aegypticus.

Here is where ages come into play. In total, there are 30 ages just in the Mesozoic. Here they are.

Early Triassic:
Induan
Olenkian

Middle Triassic:
Anisian
Ladinian

Late Triassic:
Carnian
Norian
Rhaetian

Early Jurassic:
Hettangian
Sinemurian
Pliensbachian
Toarcian

Middle Jurassic:
Aalenian
Bajocian
Bathonian
Callovian

Late Jurassic:
Oxfordian
Kimmeridgian
Tithonian

Early Cretaceous:
Berriasian
Valanginian
Hauterivian
Barremian
Aptian
Albian

Late Cretaceous:
Cenomanian
Turonian
Coniacian
Santonian
Campanian
Maastrichtian
