Identifying these ancient skulls?

Question

http://www.sfusd.edu/schwww/sch697/depts/science/wenning2/datedskulls.htm

What species do F, G, and K belong to? I find that many of the skulls look nearly identical; any tips for identifying them would be appreciated.

Answer 1

F and G belong to the homospecopolis geneous while K is definately Flantmolist. I suggest you compare the relative spectrum of the falangy when looking at the cranium of the horpolipous for a better understanding of this philem.
