' new life ') is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of insects, mammals, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic.
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.
Quetzalcoatlus, one of the largest flying animals to ever live, first appears in the fossil record. c. 66.038 ± 0.011 Ma – Cretaceous-Paleogene extinction event at the end of the Cretaceous Period marks the end of the Mesozoic era and the age of the dinosaurs; start of the Paleogene Period and the current Cenozoic era.
Another huge animal of this group was Uintatherium, with skull length of 76 cm (30 in), 1.5 m (4 ft 11 in) tall at the shoulder, [144] 4 m (13 ft) in length and 2.25 t (2.48 short tons), the size of a rhinoceros.

This list of Mesozoic birds is a comprehensive list of all Mesozoic dinosaurs that have been assigned to the clade Avialae (birds, in the broadest sense). The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are ...
