Apatosaurus, NSM Monograph #26 - Help!
My local university library has been trying to hunt down the recent
publication by Upchurch, Tomida and Barrett. So far, to no avail. Does
anyone know of ANY library in the country (U.S.) that might have a copy of
this? I promise to forward highlights of the paper to this list.

A new specimen of _Apatosaurus ajax_ (Sauropoda: Diplodocidae) from the
Morrison Formation (Upper Jurassic) of Wyoming, U.S.A.
Paul Upchurch, Yukimitsu Tomida, and Paul M. Barrett
National Science Museum, Tokyo December, 2004
ABSTRACT: In 1993, a nearly complete postcranial skeleton of Apatosaurus was
recovered from the Morrison Formation (Upper Jurassic: Kimmeridgian -
Tithonian) near Thermopolis, Wyoming (USA). This specimen was purchased by
the National Science Museum, Tokyo, where it has been mounted for public
display. Description of this new Apatosaurus material has yielded
additional anatomical data that have been used to revise the generic
diagnosis and species-level taxonomy of the genus. A
specimen-level cladistic analysis of individuals referred to Apatosaurus
identifies hitherto unrecognized phylogenetic structure and indicates the
presence of four valid species: A. ajax (the type species), A.excelsus,
A.louisae, A.parvus (comb. nov.). The latter species is based on material
of
"Elosaurus" parvus from the Morrison Formation of Sheep Creek, Wyoming
(USA). The cladistic analysis indicates that the Tokyo Apatosaurus can be
referred to A. ajax, which makes the current study the most detailed
description of this genotype species. Revised generic and specific
diagnoses have allowed re-evaluation of various specimens that have
previously been assigned to Apatosaurus, including juvenile material from
Oklahoma.
