Often when new evidence if found, it can either totally change our conceptions of the truth or help prove our hypothesis. Here are some new and interesting discoveries within the last few years that show this.
NAME: Avisaura, chicken-size, found in Utah was believed to be a bird-like dinosaur, but in actual fact was a flying bird. It lived 70-80 million years ago in the Late Cretaceous
NAME: Mononykus, (nature 93), 70 million years younger than the Archaeopteryx (the Late Cretaceous). As you can see in this picture its arms look like wings, but it has been determined that they are too small to have been able to be used for flight. Originally, it was thought to be an avian, even though it could not fly, because its supposed wings were too stubby. After more study, palaeontologists concluded that this animal may have been a specialized dinosaur-its stubby front limbs especially suited for digging up food. Its long-legged skeleton otherwise resembles predatory theropod dinosaurs such as the Velociraptor.
These two examples, prove an important
point about New Discoveries. Not everything is what it seems to be, but
more importantly even though one scientist may say that it is one thing
because of his reasons, it is never a closed book discussion. Everybody
has something to add to the evidence or present theories/hypotheses.
