when did the mesozoic era start and end
Mesozoic The Mesozoic Era ( /ˌmɛsəˈzoʊɪk, ˌmiː-, -soʊ-/ or /ˌmɛzəˈzoʊɪk, ˌmiː-, -soʊ-/[1][2]) is an interval of geological time from about 252 to 66 million years ago. It is also called the Age of Reptiles, a phrase introduced by the 19th century paleontologist Gideon Mantell who viewed it as dominated by diapsids such as Iguanodon, Megalosaurus, Plesiosaurus and Pterodactylus. This Era is also called from a paleobotanist view the Age of Conifers.[3]
Archaic Greece Archaic Greece was the period in Greek history lasting from the eighth century BC to the second Persian invasion of Greece in 480 BC,[1] following the Greek Dark Ages and succeeded by the Classical period. The period began with a massive increase in the Greek population[2] and a series of significant changes which rendered the Greek world at the end of the eighth century as entirely unrecognisable as compared to its beginning.[3] According to Anthony Snodgrass, the Archaic period in ancient Greece was bounded by two revolutions in the Greek world. It began with a "structural revolution" which "drew the political map of the Greek world" and established the poleis, the distinctively Greek city-states, and ended with the intellectual revolution of the Classical period.[4]
