70 million year old fossil found !!- Okay what purpose it will serve us?

Hi saiven...fossils are crucial study materials for scientific and anthrological studies-for example, I live in Uganda, East Africa, and some fossils of the earliest Homosapiens were found in Uldovai Gorge-these have contrtibuted to understanding the origins of man-for instance serious questions being raised with the kind of fossil find you talk about in Japan-scientists would want to know what caused the extinction of tarbosaurus, under what conditions did that dinosaur like creature live, are those conditions still there? All these would help improve understandong of our world and probably help predict the future fate of other life forms still around us! I think fossils increase human curiosity about our world from hstorical perspective!

they can estimate in the hypothesis using the radioactive machine that convert a fossilized object,,

Hmmm.. like they said "you'll never understand the present and your future unless you learn from your past". I guess this fossils will give us a hint of what the past look like and how we evolve to today. Geologist has its way of knowing of whats "what" and whens "when".

I am no anthropologist. i have heard there are many scientific ways of actually knowing the exact age of the fossil. may be the old fossils can reveal many facts of that time. i do not know exactly how these are used.

Anyways, congratulations on the people who found those. As for the purpose, I think it could serve us to see what caused the extinction of the animal or insect, etc. to let us know the possibilities of our lives here on earth. It's somehow shows the mark of things that happened or situations that endured those times thus gives us an idea what might happen and how we could survive those. So, it's actually similar to you knowing your family history. Knowing what diseases or events occurred in your family tree would somehow define who you are and what sorts of things could destroy you and create opportunities to these threats. So, there it is. That's my idea, I don't know what others or scientists have to say. =)

I think it's the constant pursuit of man to find answers, especially any question relating to "How did it all start?". Also, trying to estimate the age of the fossil can reveal how long earth has been "living". I don't know about their other methods except carbon dating. Maybe things like these help put the pieces of a puzzles together to form a bigger picture. Since I'm no anthropologist, I have no idea how. Happy mylotting too! :)

Wow!! That's amazing ! How could they predict the date!! I guess, researchers would get more clue on evolution and the kind of creatures that existed then, may be more huge that dinosaurs.....I am little blunt on this, couldn't resist responding though. It's always a pleasure discovering your name here. *laughs*

of course its means that those animals shown in tvs and in thsoe written in the books are really true or really exist and its very exciting to note that sometime they had live with us and wonder how the people during that era coexist with them....and we can imagine what kind of animals do exist during such era..im too was wondering how they can detect or estimate how old is this ..but i had read somewhere that they can through the layers of the dust or soil that covered the stone where the fossil was found...i dont know what the process called but each layer is an equavalent of million year or lesser or whatever..not really sure of...

Hello! Wow, a 70 million year old fossil! I honestly have no idea on how can they be so certain about the ages. Science is amazing, they can tell you many things that you wouldn't even imagine. They have it all studied. And still, there are so many questions to be answered. I don't think that this fossil is going to help us in any way. It is just like studying history: you are studying the past to know your roots, it's not like if it was going to help you in the future. It is always interesting to know where did we come from, isn't it? It could give the scientists more information on the world as how it as 70 million years ago. I'm sure it would have been fascinating to live on that age. Not a single house built! Respectfully, Munhozmib.

I really have no idea how they gauge the age of the things that they find. But how amazing, 70 million years old I cannot imagine something being that old. I think its really strange that they have found something that old that was once alive, I would love to see what it was like when something like that was alive.

Well, it gives us an idea of where we came from, and how things evolved. If that's really only 70 million years old, that's pretty recent in evolutionary terms. Unlikely to be carbon dating, as there's very little carbon in such fossils. Dating can be done by various other radioisotope dating methods though, similar to Carbon-14 testing. Not only that, but its depth in the geological strata would give a good idea.
