The Amazon River has been around for 11 million years ago and in its shape for the last 2.4 million years ago, according to a study on two boreholes drilled in proximity of the mouth of the Amazon River by Petrobras, the national oil company of Brazil.
Until recently the Amazon Fan, a sediment column of around 10 kilometres in thickness, proved a hard nut to crack, and scientific drilling expeditions such as Ocean Drilling Program could only reach a fraction of it. Recent exploration efforts by Petrobras lifted the veil, and sedimentological and paleontological analysis on samples from two boreholes, one of which 4.5 kilometres below sea floor, now permit an insight into the history of both Amazon River and Fan.

Tote that barge ping.
But she doesn’t look a day over nine. Ten million tops.
Do they mean the riverbed or the ‘river’....if it’s the ‘river’ that water would be mighty stale by now...
They drilled a core into the Fox River near Green Bay and found 11 inches of wood pulp.
Beaver.
Using only two points of data are what I call, in academic terms, grossly overexaggerated BS....
The bottom must be a mile deep in fish poop.
The river is not the water that flows through it any more than a highway is the cars that drive on it. ;)
Yet I imagine that many of those atoms in those water molecules have made that particular passage many times over the last 11 million years.
Maybe.
I find this very very hard to believe. There may have been rivers in the Amazon Basin area for this amount of time, but the river itself probably wasn’t. Oxbow lakes and meanders can form very very quickly and it would be very unlikely that the entire river would remain unchanged for over 2 million years
All I know is that I’m never swimming in it. I watch the show about fish in the Amazon.
Sarah Palin’s gonna have a very tough time explaining just who or what was swimming amid all those piranhas for the prior 10,996,000 years.
The mouth of the river has probably been fairly stable but I tend to agree about the river wandering.
The fish are not nearly as dangerous as the flat worms that can swim up your urethra and take up residence in your bladder.
I don’t doubt the delta has been there that long, even the source of the river, but in between can change a lot even from one bad storm.
I’m pretty sure there’s a sea monster in there somewhere.
Not true. It can’t be older than 6,000 years. Probably much younger, since it’s not even mentioned in Genesis.
What do Biden and Gore have to do with this?
Point taken...however my later post indicates that data taken from only TWO boring points, in engineering terms, can fit a buttload of different curves.....curves in this case might apply to age, possibly?
