Prehistory means literally "before history", from the Latin word for "before," præ, and historia. Human prehistory is the span of time since behaviorally and anatomically modern humans first appear, and until the appearance of recorded history following the invention of writing systems. Since both the time of settlement of modern humans, and the evolution of human civilizations, differ from region to region, prehistory starts and ends at different moments in time, depending on the region concerned. Sumeria in Mesopotamia and ancient Egypt were the first civilizations to develop their own scripts, and to keep historical records; this took place already during the early Bronze Age. The neighboring civilizations of the Ancient Middle East were the first to follow. Most other civilizations reached the end of prehistory during Iron Age.
Dinosaurs are a diverse group of prehistoric animals of the clade Dinosauria. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic (about 201 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups (and some three-quarters of plant and animal species on Earth) at the close of the Mesozoic Era. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic Period and, consequently, they are considered a subgroup of dinosaurs. Some birds survived the extinction event that occurred 66 million years ago, and their descendants continue the dinosaur lineage to the present day.
