Thanks to the Polyglot Paleontologist website
(www.uhmc.sunysb.edu/anatomicalsci.paleo), I have been able to peruse the
description of the sauropod _Abrosaurus dongpoensis_ translated by Will
Downs. No figures, alas.
Ouyang Hui (1998). A new sauropod from Dashanpu, Zigong Co., Sichuan
Province (_Abrosaurus dongpoensis_ gen. et sp. nov.). Zigong Dinosaur
Museum Newsletter 2:10-14.
Ouyang Hui refers _Abrosaurus_ to the Camarasauridae. Based on the text
alone, it's difficult to pin down its affinities. The enlarged narial
openings is not just a macronarian character, having also been found in
_Jobaria_. The author points out several primitive prosauropod-like
characters. Anyway, my knowledge of the cranial anatomy of sauropods is
awful, so I'll hold off on further musing.
Interestingly, the description mentions a new sauropod genus, Bashunosaurus,
from the same Dashanpu quarry: "Another sauropod genus from the Dashanpu
quarry, Bashunosaurus, is represented by a damaged skull. However, after
restoration, it appears to be generally consistent with Omeisaurus although
its maxillary morphology is more consistent with Shunosaurus, it lacks a
mandibular fenestra and has an even more reduced dentition, distinguishing
it further from _Abrosaurus_."
I would hazard a guess that "Bashunosaurus" is still a nomen dubium; but
after the kafuffle surrounding the status of _Abrosaurus_, maybe the
description is lurking in some obscure Chinese pamphlet or newsletter.
