Wow, what a find! This site has translations of the papers that describe
_Yandusaurus_, _Gongxianosaurus_, _Bellusaurus_... and Dollo's assertion
that the hadrosaur _Aachenosaurus multidens_ is really just a lump of wood
(first published 1888)!
Also, some interesting stuff on _Pleurocoelus_, from Salgado et al.'s
abstract. According to them:
(1) _Pleurocoelus nanus_ (type species, from the Arundel Formation of
Maryland) is the possible sister-taxon to the Titanosauria; it shows a few
titanosauriform synapomorphs (absence of phalangeal articular surfaces on
the distal metacarpals; transversely expanded distal tibia), but its
anterior caudal vertebrae are amphiplatyan, not procoelous.
(2) _P. altus_ (also from the Arundel Fm) is NOT an adult _P. nanus_; it
probably does not even belong in the same genus. _P. altus_ "exhibits an
anteroposteriorly expanded distal tibia, a character which is plesiomorphic
(3) The _Pleurocoelus_ material from the Comanche Series of Texas,
definitely does NOT belong in the genus _Pleurocoelus_. Its anterior
caudals are procoelous (albeit slightly). Based on this and other features
("dorsal vertebrae with the infradiapophyseal laminae bifurcated at their
base, and the presence of a centro-parapophyseal lamina") the Comanche
sauropod appears to be a basal titanosaur.
What a mess! If Salgado and co are correct, no less than THREE sauropod
genera are represented from among the Lower Cretaceous North American
material named "Pleurocoelus". So much for the sauropod hiatus! I hope
Salgado et al. follow this abstract up with a complete publication.
