  Calvo, Jorge O. & González Riga, Bernardo J., 2003. Rinconsaurus
caudamirus gen. et sp. nov., a new titanosaurid (Dinosauria, Sauropoda)
from the Late Cretaceous of Patagonia, Argentina. Revista geologica de
Chile 30(2): 333-353>

  Plate 3 includes a statement and photo of an _articulated_ series of
vertebrae showing procoelous, opisthocoelous, amphicoelous, and biconvex
vertebrae from two specimens, in various patterns ... the vertebrae are
prone to transformation, and it cannot be considered that in distal
caudals, titanosaurs fit a single hypodigm nor can they be expected to be
true for all titanosaurs especially since distal caudals are virtually
unknown among titanosaurs. Opisthocoely grading into amphiplatyan and
platycoelous vertebrae in *Opisthocoelicaudia* now no longer is so
"bizarre," especially since *Rinconsaurus* is applied as more basal than
*Opisthocoelicaudia.*

  Enjoy.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
