"I am not sure what the rest of the story is about, except we have this remarkable artifact that was found in disturbed ground and that the dating of
its burial is effectively irrelevant. It is clearly even to us, a non human skull and more informed inspection eliminates a terran genesis unless that
changes under further investigation.
It is an alien skull at this point unless it has been outright faked and that game will not survive a DNA analysis.
From there we can proceed to further investigation. Expert comparative taxometry can be applied and we can learn in detail why and how it differs from
mammal skulls. An DNA analysis can be generated and also compared to the human standard. From there we can even prepare the genome if it is possible.
The first question is to discover how divergent it is from humanity."
