Perusal of an article about Saddam Hussein's canal-building projects has led a scientist to a startling discovery about the mysterious collapse of Middle East civilisations more than 4,000 years ago.
Sharad Master, a geologist at the University of Witwatersrand, Johannesburg, saw on satellite images of southern Iraq a large circular depression which he believes is a meteor crater.
If confirmed, it would indicate an impact equivalent to hundreds of nuclear bombs, causing devastating fires and flooding in an area which would have been shallow sea at the time.
The discovery could explain why so many early cultures went into sudden decline around 2300 BC, including the Akkad culture of central Iraq and the fifth dynasty of Egypt's Old Kingdom, along with hundreds of settlements in the Holy Land.
Until now, archaeologists have put their demise down to wars or environmental changes. Recently, however, some astronomers have suggested meteor impacts.
"It was a purely accidental discovery," Dr Master said last week. "I was reading a magazine article about the canal-building projects of Saddam Hussein, and there was a photograph showing lots of formations - one of which was very, very circular."
The faint outline was on satellite images of the Al 'Amarah region, north-west of the confluence of the Tigris and Euphrates rivers and home of the Marsh Arabs.
Analysis of other satellite images since the mid-1980s showed that for many years the crater contained a small lake. The draining of the region, as part of Saddam's campaign against the Marsh Arabs, caused the lake to recede, revealing a ring-like ridge inside the larger depression - a classic feature of meteor craters.
Dr Master has reported his findings in the journal Meteoritics & Planetary Science.

I've been feeling a bit nostalgic lately....
About all I can add (quickly) to the discussion is that there was a severe worldwide 'tree ring' incident at 2354BC. This could have been part of a swarm? If not a swarm, it must have been pretty big event to affect the trees worldwide. (I'll see if I can find other things that may connect, later)
satellite images of southern Iraq have revealed a two-mile-wide impact crater caused by a meteor

This is twice as big as Meteor Crater in the western US.
The demise of the Akkadians is generally attributed to Gutian hordes, while the demise of the Sumerians who followed is attributed to over-irrigation causing excess salinity in the soil.
The Barringer Crater was created what, 50,000 years ago, and it's still in pretty good shape. It hit dry land, so erosion would be less than one that hit a marshy area.
Did they give the age of this Basra crater? They mentioned 4000 years, but was that the determined age of the crater?
This longer article at the Telegraph mentions this:
Yet another reason to topple Saddam's regime - so we can send in the archaeologists!The crater also appears to be, in geological terms, very recent. Dr Master said: "The sediments in this region are very young, so whatever caused the crater-like structure, it must have happened within the past 6,000 years."
Reporting his finding in the latest issue of the journal Meteoritics & Planetary Science, Dr Master suggests that a recent meteor impact is the most plausible explanation for the structure.
A survey of the crater itself could reveal tell-tale melted rock. "If we could find fragments of impact glass, we could date them using radioactive dating techniques," he said.
Ah ha. Maybe a meteor shower.
