tyrannosaur lips

["M Sakamoto, Earth Sciences" <M.Sakamoto@bristol.ac.uk>]

Hi,

Does anyone remember a recent article about the reconstruction of lips on 
tyrannosaurs where the upper and lower lips form a seal over the teeth - 
kind of like chimp lips? I can't seem to find the original reconstruction 
and I'm sure I didn't dream this up...

Can anyone reassure me that I haven't dreamt it up and remind me who's work 
that was?

Thanks,
Manabu
