The Archaeopteryx fossil was a veryimportant discovery by archaeologists. It was discovered in Southern Germany,where there are many well-preserved fossils. The Archaeopteryx fossil is theremains of an ancient bird, which is about 150 million years old. Manyscientists believe that Archaeopteryx might have been the first kind of bird ever.It is not very similar to the kinds of birds we see today. Scientists believeit was part bird and part dinosaur because it had feathers and wings but it wasalso reptilian, like the ancient dinosaurs.接下来为大家介绍"解读托福阅读考古学类短篇练习- The Archaeopteryx Fossil"
托福阅读考古学类短篇练习- The Archaeopteryx Fossil
Unlike birds in today 's world,Archaeopteryx had a full set of teeth, a flat chest, a long, bony tail, andthree claws on its wings, which might have been used to attack prey or to holdon to trees. In fact, from looking at the fossils of Archaeopteryx, the ancientcreature looks a lot more like a dinosaur than a bird.
A big debate amongst scientists is whatArchaeopteryx used its feathers for. Some scientists suggest they were used tocontrol their body temperature while others believe that they were used forflight. This is a very important question for scientists because they want toknow how animals first started to fly.
There are two theories about the origin offlight and about what Archaeopteryx used its feathers for. The first argumentis called trees-down; this is the theory that birds their feathers to glidedown to the ground from trees much like how flying squirrels do today. Theother argument is called ground-up; this is the theory that ancient birds livedon the ground and used their feathers to help them make long leaps into treeswhenever they needed to. For example, if they needed to get away frompredators, then they could jump into the trees from a great distance and holdon to them with their claws.
Scientists are curious as to why ancientbirds stroked their wings like modern birds. They believe it might be relatedto the way that some kinds of dinosaurs used their strong forearms to grabdownwards and hold on to their prey. If Archaeopteryx did this, then it mighthave learned that it could also use its strong forearms to flap its wings andstay in the air for longer periods of time. Over millions of years, animalsthat were related to Archaeopteryx might have been able to stay in the air forlonger and longer until finally they could fly like modern birds do.
