Quoted from OG
Salt deposits and moisture threaten to destroy the
Mohenjo-Daro excavation in Pakistan, the site of an
ancient civilization that flourished at the same time
as the civilizations in the Nile Delta and the river
valleys of the Tigris and Euphrates.
According to what I have learnt, when using "as" for comparison, 2 clauses are being compared. The above OG sentence is a correct sentence in OG. I think we are missing a verb in the second clause that describe the civilization in the Nile Delta.
I think the sentence should be:
Salt deposits and moisture threaten to destroy the
Mohenjo-Daro excavation in Pakistan, the site of an
ancient civilization that flourished at the same time
as did the civilizations in the Nile Delta and the river
valleys of the Tigris and Euphrates.
