New sauropod paper

My apologies if this has already been posted. I haven't seen or read this paper yet. I find the abstract tantalizing, given that it suggests the coexistence of two sauropods in Brazil, one of which is related to _Rayososaurus_ (a rebbachisaurid), whereas the other is related to _"Rebbachisaurus" tamesnensis_. AFAIK, the latter is a more primitive grade of sauropod, akin to _Jobaria_.

Medeiros, M.A. and Schultz, C.L. (2004). _Rayososaurus_ (Sauropoda, Diplodocoidea) no meso-Cretaceo do norte-nordeste Brasileiro. [_Rayososaurus_ (Sauropoda, Diplodocoidea) in the mid-Cretaceous of northeastern Brazil.] Revista Brasileira de Paleontologia. 7(2): 275-279.

Abstract: "Continental Cenomanian deposits of the Alcantara Formation at Maranhao state, Northeastern Brazil, include a paleocommunity assembling plants, dinosaurs, crocodiles, and fishes. Isolated teeth and bone debris, mainly caudal vertebral centra, are the most common identifiable elements. Comparison with an articulated, almost complete, skeleton from Neuquen in Argentinean Patagonia, and with published data revealed that most of the caudal centra from Alcantara Formation are related to _Rayososaurus tessonei_ (= _Rebbachisaurus tessonei_). Some of them also show similarity with "_Rebbachisaurus tamesnensis_" centra from North Africa. Although the confuse taxonomic status of these taxa precludes an accurate identification for the Brazilian form, this occurrence adds a link among the middle Cretaceous dinosaurian fauna from Patagonia, Northeastern Brazil and Sahara."
