Re: ?Lambeosaurus laticaudus



Thanks. At first glance (text search 'laticaudus') there's nothing on L. 
laticaudus in the paper naming Angulomastacator.

Hmm. Does anyone know what happened to the bones? The Morris 1981 naming paper 
says they are likely to go to a museum in Mexico in the future; did this happen?

As for the LACM-26757-may-not-be-?L-laticaudus issue ... am I missing 
something? Morris 1981 doesn't mention LACM 26757 anywhere (it's not in the 
list of referred specimens), but the mass estimate it cites from Morris 1972 is 
explicitly for LACM 26757.

I don't really doubt it's the same taxon; it just seems ... messy, and a 
possibly necessary piece of bookkeeping. (How *does* taxonomic/species 
assignment bookkeeping that's not complex/original enough to warrant a paper 
get published? Is there some accepted mechanism?)

no problem, you may also want to check Wagner's "Angulomastacator"
paper in regards to the problem, although I cannot remember off-hand
if he discusses it.
