Ontario is Canada's most populous and second-largest province.
As early as 30,000 years ago, we can also see evidence of some experimentation with clay: at a site known as Dolni Vestonice (Czech Republic), figurines made of clay mixed with crushed mammoth bone were found.
The oldest evidence of pottery manufacture has been found at an archaeological site known as Odai Yamamoto, in Japan, where fragments from a specific vessel have been dated to about 16,500-14,920 years ago.
Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.
Carbon-14 has a half-life of about 5730 years, and therefore it is used to date biological samples up to about 60,000 years in the past.
Two-thirds of the province lies under the Canadian Shield, which covers most of the north, with the exception of the Hudson Bay Lowland.
The Shield’s southern-most boundary forms a triangular wedge, extending from Georgian Bay in the west to its apex near Brockville on the St. To the east lies the eastern Ontario plain, between the Ottawa and St. To the west, from Kingston on, there are belted rolling hills and plains culminating in the flat country in extreme southwestern Ontario.Due to its abundance and durability, pottery is one of the most common types of items found by archaeologists during excavations, and it has the potential of providing valuable information about the human past.Clay is abundant, cheap, and adaptable, which makes it convenient for human exploitation.Scholars and experts hand-picked by Beijing to work on the project say only they will be able to make entries — the latest example of the Chinese government's efforts to control information available on the internet.The scholars say truth is their guiding light, and their editing and review process is a rigorous one.Furthermore, if a sample has been contaminated, scientists will know about it.
