Ok People, Heres another good well, 'interesting discovery...
You'll find it on: http://news.xinhuanet.com/english/2005-06/...ent_3049613.htm
If you can't be bothered to look there, heres what the article says:
Scientists resolve dinosaur s** riddle in part

BEIJING, June 6 -- A Tyrannosaurus rex recently excavated in Montana, U.S. has surprised scientists. A layer of medullary bone found inside the leg bones of the animal - a most improbable discovery after 70 million years - showed it was an ovulating female.
The finding provides a way to tell at least some dinosaurs' sexes. Until now, distinguishing the s** of dinosaurs has been impossible without well-preserved pelvic bones.
Medullary bone is a calcium-rich layer that develops in the long bones of birds during the egg-laying process. It provides a supply of calcium to form eggshells.
Moreover, after careful testing, the scientists led by Mary Schweitzer of North Carolina State University determined that the estrogen-derived tissue was similar to substances now present only in living birds that produce eggshells.
The team concludes in a report in Friday's issue of the journal Science that the finding "solidifies the link between dinosaurs and birds" and "provides an objective means of gender differentiation in dinosaurs."
This discovery won't enable paleontologists to determine the s** of all dinosaurs, however, since medullary bone is present only during the egg-laying cycle. But when it is present, it at least enables them to say that particular example is female. Enditem

Hmmm... I'm debating explaining the scientific facts behind this... didn't I mention them before? I saw a talk on this at the Society of Vertebrate Paleontology meeting last year and its not as exciting as it sounds, unfortunately, but of course the media won't tell you that. /tongue.gif" style="vertical-align:middle" emoid=":P" border="0" alt="tongue.gif" />
In all reality, while the tissue is soft, it was only made so through numerous, very vigorous chemical baths which have very likely destroyed any remnants of DNA, assuming that they were ever there in the first place. So to destroy hopes and dreams, probably no cloning... I think that's all the further I need to go. /tongue.gif" style="vertical-align:middle" emoid=":P" border="0" alt="tongue.gif" />
And the medulary bone stuff is pretty cool and may actually prove to be very soundly based. I'm interested to see further research they do on it.
