Re: Giant raptor claw found
In a message dated 97-12-07 14:59:42 EST, you write:
What happened to the repeated names?
Like _Bison bison bison_, or _Pica pica pica_?
What do you mean what happened to them? Why there aren't many of them anymore?
Well, tautonyms, which is what repeated names are called, aren't all that
common anyway. They usually result from a species in a genus turns out to be
in the wrong genus, and is accordingly transferred into another existing
genus. The species name stays the same when the genus is changed. If the genus
is the same as the species (say the species _badis_ is transferred into the
genus _Badis_), then you have a tautonym (_Badis badis_). Tautonymy is illegal
in botany according to the ICBN (International Committee on Botanical
Nomenclature). In zoology, you probably don't see it that much in recently
named things because A. In the "olden days" it was much more likely to
misassign species to a genus, with all the namings in many wastebasket genera,
and B. It just isn't all that prevalent in most of the names one who is geared
towards large vertebrates (that's just an assumption based on this being the
DINOSAUR list, after all...) sees. I would think that it still happens often
in the myriad of names in say, entomology (correct me on that if any invert
people say otherwise.) Also, one thing supposedly behind naming is to get
information about the organism in the name (of course that is never done
:-} All the names nowadays are named after someone...), so the situation where
a species is the same as the genus of a closely related genus is hard to come
I can't think of any dinosaurian tautonyms off the bat...does _Liliensternus
