What is an Archaeopteryx?
The word archaeopteryx means the first winged ones It is a scientific name given to a group of the earliest flying birds and to one in particular These daring Wright Brothers of the bird world lived about 150 million years ago during the Jurassic Period of earth's history when most of the animals were dinosaurs There were large and small dinosaurs Some walked on two legs, some on four, some lived on land and some in the sea All of them were cold‑blooded, scaly‑skinned, egg‑laying reptiles
During this period, the earth enjoyed a mild climate and the ancient seas slopped over onto vast areas of the land These conditions suited the dinosaurs just fine and they branched out into‑an amazing assortment ' of shapes and sizes Later, when the swampy land dried, countless numbers of their fossilized bones were preserved in the hardened earth
Big sturdy bones of course, tend to make the best fossils, for they are strong and durable The bones of small animals tend to break apart in the crushing layers of the earth's crust The fragile bones of a bird are small and hollow, and a bird fossil is very rare indeed However, once in a while an early bird fell into a swamp and the imprint of his feathery body was pressed into the soft mud and sealed there as the mud hardened into a sedimentary rock,
One of the earliest birds fall into a swampy lagoon in what is now
Bavaria, The water teemed with weeds which took minerals and made them into crusty calcium Later, the swamp became dry land and the ancient bird was sealed in a layer of limestone His remains ware discovered when the limestone was mined to be used in a special process of printing words and pictures Also sealed in the ancient limestone were the fossil remains of turtles and cuttlefish, dragonflies and ancient crocodiles
From these and other records were rebuilt a picture of the archaeopteryx and the everyday world in which the first birds took to the air Their bodies were no larger than crows, but their feathery pinions mush have made them seem much bigger They had strong feet, suitable for running and perching The head, body and tail, however, were more like that of a lizard than a modern bird In fact, the experts tell us that the first birds were members of the reptile family and all our birds share their remote ancestors with the dinosaurs
The archaeopteryx of Bavaria had a long lizard body bordered on each side with a fringe of stiff, flat feathers He had a long, lizard snout and sturdy haws crammed with sharp teeth Has leathery wings were tipped with stiff pinions The imprint of his skeleton shows that his wing bones were very like the arm bones of his ancestors In facts claws like those of his scrappy ancestors still poked forth from the ends of his fossil wings
