"Skeletons in the Sand" PBS show

[Bernard Silver <bernard@gte.com>]

I just watched the above for the nth hundreth time (my daughter's
favourite thing to do is to watch this video).  It is about Serreno's
discovery of the Afrovenator (and the other as yet un-named sauropod)
in Niger in 1993.

There are a lot of strong statements made in the program (by the
narrator), including that, prior to these discoveries, almost
nothing is known about Cretaceous dinosaurs in Africa, later
specialized to nothing is known about carnivorous dinosaurs in the
African Cretaceous.   Since Spinosauras is a Late Cretaceous dinosaur
found in Niger, and they talking about 130 mya, I assume they really
mean the early Cretaceous.  

How little is/was really known about early Cretaceous African
dinosaurs?  I'm trying to seperate hype from truth!

Thanks
