Claim
built-in 847
Correction

The Great Mosque of Samarra was not built in 847. UNESCO’s nomination dossier dates the mosque to 849–852.

Full reasoning

This date is contradicted by UNESCO’s official nomination dossier for the Samarra World Heritage site. In its description of the Great Mosque, UNESCO states that the mosque “was the largest mosque in the Islamic World when it was built between 849 and 852.” That places construction after 847, so the article’s date is incorrect.

Claim
It lasted from 5,500 BCE and eventually collapsed in 3,900 BCE.
Correction

This date range is too late at the end. The Samarra culture is generally dated to roughly 5550–4800 BCE, not to 3900 BCE.

Full reasoning

The sentence is describing the prehistoric Samarra/Samarra culture. Standard archaeological dating places the Samarra culture in the 6th to early 5th millennium BCE, ending around 4800 BCE rather than 3900 BCE. An MIT OpenCourseWare handout lists “Samarra Culture (5550–4800 BCE)” and places Tell es-Sawwan at “ca 5500–4800 BCE.” A classic excavation report on Tell es-Sawwan likewise says the site’s occupation stretched only into the early fifth millennium BCE, which is still about a thousand years earlier than 3900 BCE.

Claim
127
Correction

The yearly precipitation total in the climate table is arithmetically wrong. The monthly values shown on the page add up to 171 mm, not 127 mm.

Full reasoning

This is an internal calculation error in the climate table itself. The monthly precipitation values listed are 25, 30, 29, 21, 8, 0, 0, 0, 0, 4, 20, and 34 mm. Adding those values gives 171 mm, so the table’s year total of 127 mm is incorrect. This also matches the prose immediately above the table, which says that about 171 mm of precipitation falls annually.
