Yes, the 99-million year old bird wing found encased in amber will impart a great deal of important information to the science community. Discoveries like this one provided insight into the past, into evolution, and even into the present. They often open up new concepts and questions, adding to the science community and human knowledge.
Yes, the discovery of a 99 million year old bird will give important information to the science community if the discovery is actually true. The is no reason to believe that the bird is actually 99 million years old because there is nothing else that was around from that time period by which to verify the age of the bird. However, the bird can give important science information.
This will impart important information to the science community if they are allowed to study it it. Science is about learning continuously and adapting to new information. There is no telling what scientist can learn or what will change as they learn. Learning new this through this discovery can change what we know already.
Absolutely! Finding something accurately dated to 99 million years ago would be absurdly useful to the science community. It could open up so many avenues for learning -- about the age of our planet and universe, about evolution, and about the conditions that existed then, among other things. Studying history through fossils and preserved items like this is enormously valuable and important to science, and to learning more about past conditions and, potentially, what that means for our futures, as well.
