Titanosaurs from Malawi
This is at the Palaeontologia Electronica website, so I don't know if it
qualifies as a valid publication. Therefore, I do not know if Karongasaurus
gittelmani is a valid genus and species yet (I suspect not).
Sauropod Dinosaurs From The Early Cretaceous Of Malawi, Africa
At least two titanosaurian sauropod taxa have been discovered in the Early
Cretaceous Dinosaur Beds of northern Malawi, Africa. One of these,
_Malawisaurus dixeyi_, is represented by cranial elements, 18 cervical
vertebrae, 10 dorsal vertebrae, a sacrum, 51 caudal vertebrae, 24 chevrons,
pectoral elements, pelvic elements, and dermal armor, all of which are
described and illustrated. The cranial elements indicate that _Malawisaurus_
had a short, high macronarian skull. _Karongasaurus gittelmani_ gen. et sp.
nov. is more derived than _Malawisaurus_ but is represented only by a
dentary and isolated teeth. Some indeterminate vertebrae may also belong to
_Karongasaurus_ or another taxon, but not to _Malawisaurus_. The shape of
the teeth and jaw, and the restriction of teeth toward the anterior part of
the jaw in _Karongasaurus_ are different from _Malawisaurus_ and suggest
that _Karongasaurus_ had a long, low skull. Thus, the sauropods from the
Malawi Dinosaur Beds demonstrate extreme morphological variation in
titanosaurian jaws, teeth, and probably skull shape. Variation in tooth and
skull morphology, because of its relevance to feeding, was likely of
significance in resource partitioning among titanosaurian sauropods in the
Early Cretaceous ecosystem.
