Weatheredmegacrystic Crathes Granite in Littletown quarry near Dunecht(Aberdeenshire, Scotland). This rock is from the current CenozoicEra.TheCenozoic Era began about 65 million years ago, following the MesozoicEra, which was the era of the dinosaurs. The Cenozoic is sometimescalled the “Age of Mammals”, as most land animals during this erahave been mammals. However, the history of mammals began long beforethe Cenozoic, and the diversity of Cenozoic life is far wider thanjust mammals.TheCenozoic is divided into the Tertiary and Quaternary periods, thelatter covering the last 1.8 million years. The Quaternary is thendivided into the Pleistocene and Holocene.Ourcurrent geological epoch, the Holocene, covers the last 11,700 years. It began after the last glacial period and the last glacial retreat. Some consider it an interglacial period within the Pleistocene Epoch(the Flandrian Interglacial).  The Holocene is identified with thecurrent warm period. -- source link
