One can see the cranial sutures in several of the skulls. I would speculate that the front fontanel was perhaps much larger than in humans at birth and afterwards, allowing for the expansion of the skull as the brain grows.
Maybe the skull grew sort of line an antena...
That distinct lateral ridge is bizarre isn't it, almost like a second skull.
As Gaby mentions it looks as though the fontanelle was fully circumferential therefore allowing for vertical extension after birth.
Gotta say I'm intrigued at what sort of brain configuration would be contained in there!

That made me laugh too
