Cretaceous Sauropods from the Sahara and the Uneven Rate of Skeletal 
Evolution Among Dinosaurs

Science 286(5443): 1342-1347 [Nov 12 1999]

two new African sauropod genera and species are described, namely, Jobaria 
tiguidensis and Nigersaurus taqueti

and their genera become #866 and 867 in the Dinosaur Genera List:

Jobaria Sereno, Beck, Dutheil, Larsson, Lyon, Moussa, Sadleir, Sidor, 
Varricchio, G. P. Wilson & J. A. Wilson, 1999

Nigersaurus Sereno, Beck, Dutheil, Larsson, Lyon, Moussa, Sadleir, Sidor, 
Varricchio, G. P. Wilson & J. A. Wilson, 1999

With merely 11 authors, this description still falls two short of the 13 
authors of the Suchomimus paper.

Jobaria (named after the Tuareg mythical creature "Jobar") is described as a 
primitive camarasaurid-like macronarian with a short neck of 12 cervicals and 
broad teeth, known from a number of individuals. Nigersaurus (named after the 
Niger Republic) is described as a rebbachisaurid diplodocoid with unusually 
numerous small teeth and a broadly squared-off snout. Both are from the Lower 
Cretaceous of the Niger Republic, roughly contemporaneous with Afrovenator, Ou
ranosaurus, Lurdusaurus, and Suchomimus.

I'm sure we'll be hearing plenty more about these dinosaurs in the near 
future. Most of the good stuff in the descriptions and phyletic analysis is 
in the article's footnotes.
