 It was originally described informally as a hadrosaurid in one of the
Fossils of Arizona volumes. (I bet Tracy Ford has the reference). When I
saw it I told them they had a sauropod and suggested they bring it uo to
Dinofest in Tempe and show it to Jack McIntosh, which they did. Jack
identified it as a slender limbed brachiosaurid.
 
 Now how does it compare to Pleurocoelus (= Astrodon "teeth").
 
  In the Cedar Mountain of Utah we have Pleurocoelus type things
spanning the Aptian through Albian. I expect there will be several
related taxa when someone works the material up.

By the way our Gastonia, Eolambia, Nedcolbertia, and Zuniceratops and
Bakker's Eobrontosaurus will all be named and described in New Mexico
Museum of Natural History Bulletin #14. Bakker also describes a Jurassic
mammal in it. It is at the printer and copies will be availible for
viewing and ordering at SVP and for purchase at our Early Cret.
Symposium at the beginning of Oct. The volume includes 36 papers
covering the terrestrial faunas of the Early to "mid." Cretaceous all
over the world. At $40.00 (prepublication price) it is a real bargin.
