New Moroccan sauropod paper
One more for the long list of unassociated sauropod limbs:

2004. The first record of a sauropod dinosaur from the Late Cretaceous
phosphates of Morocco. Journal of African Earth Sciences 40 (1-2): 81-88.
"Sauropod dinosaur remains have been discovered recently in the Late
Cretaceous (Maastrichtian) phosphatic deposits of the Oulad Abdoun Basin,
near Khouribga (central Morocco). The material consists of right hindlimb
bones (femur, tibia and fibula) from a small-sized individual. The marine
associated fauna, mainly selachians, actinopterygians, turtles, mosasaurids
and plesiosaurs, suggests a marine depositional environment, so that the
dinosaur remains may be a remnant of a floating carcass. The femur exhibits
a prominent lateral bulge on the proximal one-third, a diagnostic feature of
Titanosauriformes. The Moroccan sauropod lacks synapomorphies of
Titanosauria and less inclusive clades (i.e., distal tibia expanded
transversely to twice mid-shaft breadth; femoral distal condyles angled
dorsomedially relative to the shaft); therefore, it is here assigned to a
basal titanosauriform as Titanosauriformes indet. This is the first sauropod
reported from the Maastrichtian of Morocco and one of the few dinosaur
records from the uppermost Cretaceous formations of northern Africa. This
discovery confirms the wide geographical distribution of Titanosauriformes
during the Late Cretaceous and supports their survival into the Late
Maastrichtian of Africa."
At least this time, unlike _Phosphatodraco_, they held off and didn't
give a name to restricted material.
By the way, are any Titanosauria known from Africa, or was it the
exclusive domain of more basal forms?
