More lambeo infor (was Re: Family Ties)



In reply to :

 < As for the supposed composite nature of the beast, recent work by
French paleontologists in China (I can't recall if it is Taquet or
Buffetaut, and incidentally the other disagrees with the first...)  have
found multiple partial skulls of Tsintaosaurus, including additional
specimens with the vertical crest.  It does seem to be distinctive, a
lambeosaurine, and an interesting critter.>

The paper "Tsintaosaurus spinorhinus Young and Tanius sinensis Wiman: 
a preliminary comparative study of two hadrosaurs (Dinosauria) from the
Upper Cretaceous of China" by Eric Buffetaut and Haiyan Tong has been
published in the C.R. Acad. Sci. Paris, t. 317, serie II, 1993, pp
1255-1261. 
The results of their comparative study were that Tsintaosaurus spinorhinus
and Tanius sinensis are two different taxa. 
It sounds reasonnable for these authors to place Tanius sinensis in the
subfamily Hadrosaurinae and Tsintaosaurus spinorhinus in the subfamily
Lambeosaurinae and they think that it does possess a hallow nasal spine, 
formed mainly by the nasals and directed anterodorsally.
For Taquet the reference is "The status of Tsintaosaurus spinorhinus
Young, 1958 (Dinosauria), in the Fifth symposium on Mesozoic terrestrial
ecosystems and biota. Extended abstracts, contributions from the 
palaeontological Museum, 364,
Oslo, 1991, pp. 63-64".
Taquet interpreted the spine in Tsintaosaurus spinorhinus as an artefact
caused by post mortem displacement of the nasals. 
These papers show the different position of the two French paleontologists
Taquet and Buffetaut about these taxa.
