Re: China feathered dinosaur & flora re-dated
To be specific, they are now considered middle Barremian (*mid*-Early
There is more information on _Nature_'s web site (the article is
appearing in this week's _Nature_).
In order to read the commentary, you must sign-up for on-line access to
_Nature_. (user name and password are needed. It's easy, and _Nature_
doesn't spam. It takes about a minute to sign up.). Unfortunately, not
all _Nature_ articles are available on line for free (in fact,
relatively few are), but it is still worthwhile to get a user-name and
password for access to what is available.
Click "This weeks Nature" and scroll down to the "News and Views"
section. Look for "Palaeobiology: A refugium for relicts", by Zhexi
Next, check out the research article, itself, on-line (yes, it's a
free-bee this week, the whole paper is available!), entitled "Cretaceous
age for the feathered dinosaurs of Liaoning, China" by CARL C. SWISHER
III, YUAN-QING WANG, XIAO-LIN WANG, XING XU & YUAN WANG. (it's a
"Letters to Nature" article).
Not exactly something to tweek the passions of a the typical dinosaur
fan, but to a geologist and bio-stratigrapher, it's very interesting :-)
As a side note, I came away from the article feeling that this whole
geo-chron. matter could have been resolved years ago..... :-/
