Answer: The shape of the skull and the supraorbital height tell us the following about each species-
- It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
- Most of the species possess similar skulls as mostly their structures are  oval shaped, sloped or round shaped. 
- Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
- Variation in teeth and face shapes could also be due to different geological locations.
- In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after. 
- Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
- It also tells what probable causes of death would be when the species died.
