So overall we have 8 braincases or parts of braincases. Six contain enough of the structure for us to be sure they are unique. Two are fragments that apparently don't fit on any of the other larger parts, so I'm confident that they represent unique individuals as well. Given that we also have bones from a vey small individual and a bone from a very large individual, this brings us up to a total of 10 individuals in this find!
Here are pictures of the braincases I have copies of. Two of the original braincases were sent to Alaska before I got a chance to scan them, so I don't have the files to print 3D copies. The two fragments are at the lower left. And the grey one on the lower right is the latest one that I've just finished preparing.
Here is a short video about preparing the braincase. Sincerely, Greg Carr
Here a couple of highlight pictures to show where braincases fit into the skulls. The backbones attach to the skull at the Occipital Condyle, with the hole for the spinal cord just above.
