Remember in the movie Jurassic Park where Richard Attenborough tells Sam Neil et al that his scientists obtained Dino DNA from prehistoric mosquitoes that had been encased in amber. Well wouldn’t it be better just to have the dinosaur itself be encased in amber, or at least a part of one. Well it’s happened, a Chinese paleontologist named Xing Lida found the remarkable specimen in an amber market in northern Myanmar.
The specimen is just a portion of the tail of a very small dinosaur, and it’s covered in feathers. Now, it’s not a bird, X-rays revel that the tail bones are arranged differently than those in birds. In fact paleontologists have identified the fragment as belonging to a member of the coelurosaurian group and therefore a relative of the Mighty T-Rex and the well known velociraptors. Although this animal probably only grew to the size of a small bird.
Researchers haven’t been able to obtain any DNA but they have found soft tissue and decayed blood. This specimen has already given scientists a better idea of how dinosaurs, at least some, where covered in feathers rather than scales making them better able to control their body temperature and could provide the final proof that at least some dinosaurs were warm blooded.
Looking for ordinary fossils is like looking for a needle in a haystack but trying to find such spectacular specimens in amber is certainly needle in a haystack squared. Nevertheless you can be confident that dino hunters out there will be on the lookout and before to long maybe they will find that one specimen that does give us our first actual sample of Dino DNA.
P.S. A couple of posts back I talked a little bit about Cosmic Inflation after the Big Bang and how some cosmologists, and me, think that a simpler model is to look at the Big Bang as a Big Bounce from a previously contracting Universe. Well, Nova Next from PBS just released an article which goes deeper into that very subject. If you’re as interested as I am you can check it out by clicking below.
I’m amazed, I have to admit. Seldom do I come across a blog that’s both
equally educative and engaging, and without a doubt, you have hit the nail
on the head. The issue is something too few men and women are speaking intelligently
about. Now i’m very happy I found this in my hunt for something regarding this.
With havin so much content do you ever run into any problems of
plagorism or copyright infringement? My site has a lot of exclusive content I’ve either written myself or outsourced but it appears a lot of it
is popping it up all over the web without my agreement.
Do you know any ways to help prevent content from being
ripped off? I’d certainly appreciate it.
Thanks for the comment. I’m afraid that with cut and paste there’s little you can do about someone stealing some of your content. It really isn’t worth getting upset about!
