Talk:10th millennium BC
From Wikipedia, the free encyclopedia
Removed these four items - the temperature change claimed is extraordinary; they sould be not be included without supporting evidence - MPF 14:37, 19 Jun 2005 (UTC)
- Circa 10,000 BC– Antarctica Polar temperatures rise as much as 60 degrees over 50 years
- Circa 10,000 BC– Greenland: Ice cores reveal a 59 degree temperature increase at the North Pole and a large scale release of methane hydrate from the seafloor into the atmosphere.
- Circa 10,000 BC– World: Ice age ends and global temperatures abruptly rise 20 degrees or more.
- Circa 10,000 BC– Antarctica: Ice-free period, which has been put by different researchers everything between year 13000 and 9000 BC.

Peer review request added by MPF on basis that a large number of additions by User:65.82.31.49 are very improbable (the four worst examples removed and listed above) - MPF 15:03, 19 Jun 2005 (UTC)
[edit] Before 10th millennium BC
- I suggest to expand previous dates like 11th millenium BC because Upper Paleolith is event but not a timeline. Igor Skoglund

Armenoids in Polynesia: is it a hoax? Any references to confirm this? --Mzabaluev 21:17, 20 August 2005 (UTC)
Note to MPF. All the information entered from me in April 2005 was from months and months of internet research/google searches and was meant to add content to an empty portion of the encyclopedia (where there was nothing before I wandered by) The only real filter I put on the information provided was that it was found on at least three different websites. I found the information interesting, not found in classic learning material, and wanted to see if someone would challenge me.... Thank MDF for giving it all a once over. Other info I had collected and added was on these sections

[edit] I suggest this information be suitably incorporated somewhere.
...The alluvium samples of northern palaeochannel were tested at the behest of NIOT by Manipur University. The top alluvium collected just below marine sediment was dated to be around 3000 BP and a slightly lower alluvium gave an age of about 5000 BP. A black alluvium which was somewhat semi consolidated and collected above the river conglomerate gave an age of 19000 BP. Obviously the river has been flowing at least between 19000 years BP, prior to Glacial Maxima and up to 3000 BP. This shows that the palaeo channel in the north was active and a riverine regime existed at least from about 19000 BP....
Sample from the same carbonized wood was sent to National Geophysical Research Institute, Hyderabad, India and Geowissenschaftlicte Gemeinschaftsaulguben, Hannover, Germany for Carbon dating. This was the first sample (Location 21o 03.08’ N ; 72 o30.83 E) from near the southern palaeochannel. This first gave a clue to the age and environment of the civilization. The calibrated age as per NGRI was 9580-9190 BP and as per Hannover Institute it was 9545-9490 BP. It means the age is about 9500 BP and this takes the age by more than 4000 years older than the oldest city civilization of Mesopotomia and a fore-runner to ‘Harappan’ civilization....
As expected the one of the pottery piece whose figure is given, gave a date of 13000 ± 1950 BP. It is an important date. Another pottery piece which was ill-fired, on OSL dating (Location 21 o12.54’ N ; 72 o 30.370’ E) by Oxford University gave an age of 16840 ± 2620 BP. These are the oldest fired pottery pieces obtained sofar in the world. Till the results were out it was from Japan where the oldest potteries were known. The “Jomon” Pottery from the Fukui cave in Kyushu gave 12000 BP uncalibrated age. The pottery findings from Odai Yamamoto gave uncalibrated age of 13500-13800 BP. In the Gulf of cambay civilization already attempts appear to have been made in experimental pottery making......These are seen from effects of fired clays (for making pottery) which gave ages of 20130 ± 2170 BP (Location 21 o 13.720’ N ; 72 o 26.190’ E) and 16600 ± 1150 BP (Location 21 o13.80 ‘N ; 72 o 26.10 E), by OSL as determined by the Oxford University dating lab. The well fired 3 potteries in the northern palaeochannel gave ages of 7506 ± 785 BP, 6097 ± 611 BP (both by Manipur University) and 4330 ± 1330 BP by Oxford University.
Apart from this sun-dried Pottery pieces were collected in these areas. Three of the specimens were dated by OSL facility in Oxford. The results obtained are (1) 31270±2050 BP, (2) 25700±2790 BP and (3) 24590±2390 BP. A black slipped dish which was also sun dried was dated in Oxford by OSL. This gave an age of 26710 ± 1950 BP.
The hearth material from the southern township (Location 21o03.04 N 72o30.70 E) by TL dating from PRL, Ahmedabad gave an age of 10000 ± 1500 BP whereas the hearth material near the top in the northern township gave an age of 3530 ± 330 BP by OSL, Oxford University...
From the above it is quite clear that the human activity is very evident from about 31000 BP in what is now in the Gulf of Cambay much before the Glacial Maxima at 18000 BP. The ancients were making potteries and were getting them dried initially in the sun. From about 20000 years, it is clear that the ancients are firing the clay to produce pottery. That means they knew how to make, maintain and manage fire. They appear to have succeeded in making fired pottery from about 16800 BP. They knew the art of construction of towns and houses in neat straight line, row after row as picked up by Side Scan Sonar image and wattle and daub structure and from rammed floor. Both the northern and southern townships have continuous habitational sites interspersed with big structures in between. But good quality fired pottery makes it appearance from about 13000 BP...

- This issue is discussed extensively on Talk:Ruins in the Gulf of Cambay. The consensus is that the "pottery" found in the Gulf of Cambay are just naturally occurring concretions. The source that you cited is Graham Hancock, a pseudoarchaeologist. --Sean Brunnock 11:23, 30 June 2006 (UTC)
