A resulting file of the reference planes and bony labyrinth
endocasts for Petauroides volans is shown in Figure 1.
Endocasts for this analysis came from two other partial H. naledi skulls.
Then they compared the two endocasts with those for seven fossils of early cynodonts — carnivorous reptiles that are close relatives of the first mammals — as well as with
endocasts for 27 other primitive mammals that lived between 65 million and 190 million years ago and with the brains of 270 living mammals.
