OMEISAUR CLUBS, PACHYRHINOSAUR
I didn't keep the emails unfortunately, but there was some
recent discussion here on the ostensible tail club of
_Omeisaurus_. Pete suggested that the tail clubs attributed
to this animal may in fact have come from _Shunosaurus_.
Ye et al. recently reported the presence of an expanded
club-like structure on the tail of _Mamenchisaurus
hochuanensis_ (_Vertebrata PalAsiatica_ 39, 266-271).
They describe the distal caudals as fused together and
forming a 'cocks-comb' shaped lump. If they are correct and
this is not some sort of bizarre pathology then the presence
of such a structure in _Mamenchisaurus_ could support the
presence of a tail club in _Omeisaurus_. Incidentally, Ye et
al. regard _Omeisaurus_ as club-bearing and describe its
club as hammer-shaped and thus like that of
Ben Creisler reported...
> New species of Pachycephalosaurus from Alberta:
Ben made a freudian slip... this is the Pipestone Creek
_Pachyrhinosaurus_, not _Pachycephalosaurus_.
Finally, 'Leonardo' the new brachylophosaur specimen from
Montana (also reported here by Ben) allegedly has a tongue
preserved. Assuming it >is< a tongue I think this is a first.
