Re: Tiantai(o)saurus Dong et al. 2007, missed Chinese therizinosaur?

Ben Creisler

Many thanks to Wenjie Zheng for this update:

Prof. Dong Z.M. and local museum reconstructed the skeleton and wanted
to name it as Tiantaisaurus, but the description of the specimen has
not published yet.


The name would be "Tiantaisaurus" then, pending official publication.
