Calotte or Carapace?

Is this the top of a hominid skull, replete with sagittal crest running down the middle, or is it the top of a tortoise shell?

This image comes from great resource I just found (thanks to Louise Leakey on Twitter) for paleoanthropology students – africanfossils.org. I won’t answer here whether this is hominid or turtle, you’ll have to find it at the African Fossils site.

The site has 3D, manipulable images of fossil hominids and other animals from Kenya and Tanzania. The Smithsonian Museum of Natural History also has a very nice 3D collection, similarly manipulable. Resolution isn’t always what you might want it to be (for instance, you won’t be able to tell if the basi-occipital suture is fused in the Homo erectus cranium KNM-ER 42700), but you still get good overall view of some neat and bizarre animals. Like this robust australopithecus! (KNM-ER 406) Hey, its brain case does look kinda like the pic above…
