P. Taquet et Da. Russell, NEW DATA ON SPINOSAURID DINOSAURS FROM THE EARLY CRETACEOUS OF THE SAHARA, Comptes rendus de l'Academie des sciences. Serie 2. Sciences de la terre et des planetes, 327(5), 1998, pp. 347-353
New occurrences of spinosaurid dinosaurs from the Aptian of Niger and
Albian of Algeria augment our knowledge of Spinosaurus maroccanus and
permit the description of a new taxon: Cristatusaurus lapparenti from
the Gadoufaoua locality (Niger). Spinosaurs may be separated into two
distinct groups: one with longirostrine muzzles and premaxillae wh ich
are rounded in cross-section, and a second with brevirostrine muzzles
possessing a dorso-posteriorly expanded crest. The spanish genus Pele
canimimus may be related to spinosaurids, rendering spinosaurs a more
diversified group than previously thought. ((C) Academie des sciences
