Yes, the skulls on right are of giraffe then one of buafflo wildebeest and I think elephant jaw or hippo with a bunch of bones. No those were pickups from the area. The whole area is full of bones from animlas that have been caught by lion, leopard, hyenas and other predators.

After seeing it in the Selous I'm sure they have a clean up team in the Kruger National Park as you never see bones like that lying around and they still have the same percentage if not more of predators.
