Are dinosaurs mentioned
Yes, living dinosaurs are mentioned in history but they are not called dinosaurs, because the word "dinosaur" was not invented until 1841. History before 1841 refers to dinosaurs, but they are called dragons. History has many stories about dragons, in fact history as written at the time, often have numerous accounts of people encountering and killing dragons. The descriptions of these dragons, match those of known dinosaurs. These accounts are dismissed by most historians as myth and legend do to the influence of evolutionary thinking but if taken at face value they seem to be descriptions of encounters with living dinosaurs.
Dragons accounts from the British Isles.
St George; the Patron Saint of England; is said to have killed a dragon whose description matches that of an allosaurus. This occurred under the rule of the Roman Diocletian, in the 4th century A.D.
Near the village of Boldragon is a carved stone, said to mark the place where a knight called Martin killed a dragon, that had devoured nine maidens.
In Cawthorne (South Yorkshire) a flying dragon, is said to have once lived in the well. Because of this it is called Serpent's Well. It is said that this Dragon was often seen flying east to Cawthorne Park.
A small dragon is said to have once lived in Kellington (Yorkshire). It was killed by a shepherd named Armroyd, wielding nothing other than his shepherd's crook. This account is possibly related, to the Kellington Serpent Stone. It is a grave stone with a cross and a serpent on it.
A hill near Wormshill (Kent) was reputed to have been the resting place for a dragon.
A dragon is said to have once lived in a cave near Lewannick. (Cornwall) Any human who ventured into this cave was killed. One day St Samson was in the area and heard of the dragon. He walked right up to its cave and dragged the dragon out using his linen belt and then threw the creature into the River Inny.
In Llandeilo Graban (Powys) it is said that a dragon once nested in the belfry of the local church. It ravaged the neighborhood. One day a blacksmith made a dragon out of iron and set it in the nest; when the dragon was away. When the dragon returned it attempted to remove the impostor triggering a mechanism thrusting sharp spikes into the creature, killing it.
Other Dragons from around the world.
Ancient China has many stories about dragons.
In Babylon's epic of Gilgamesh, Gilgamesh is said to have killed a dragon.
In "Bel and the Dragon," a book that is part of the Apocrypha, the Babylonians had a dragon that was worshiped as a god. Daniel is said to have poisoned and killed it.
There are many others such accounts from all over the world, and the descriptions of these dragons match known types of dinosaurs.
When one looks at the standard picture of a dragon, it turns out to be an amalgam of various kinds of dinosaurs. It has the general body shape of a sauropod like diplodocus, the wings and tail of a pteradactyl, the teeth of a tyrannosaurus rex, the claws of a raptor, the plates of a stegosaurus, and the backward pointing horns of a styacosaurus. This is what one would expect if people had seen the animals we call dinosaurs, and over time the numerous verbal descriptions got mixed together to form a combined description from several different kinds of animals.
