Mamenchisaurus Posture Paper

[Mike Taylor <mike@miketaylor.org.uk>]

I have just run into this two-year-old popular article:
http://english.peopledaily.com.cn/200307/04/eng20030704_119448.shtml
which says:

        Contrary to the fallacy that Mamenchisaurus could
        stride forward with its head held high, study on the
        neck bones of a well-preserved dinosaur revealed that
        it could raise its head only slightly higher than the
        body within an angle of 20 degrees.

        Dr Ouyang Hui with the Chengdu University of Science
        and Engineering in Sichuan Province said that if the
        head and neck span was 6.5 meters, the most
        comfortable head position would be within 2 meters
        above its body.

Does anyone know the reference for the paper this article is based on?
Thanks.
