Research groups such as universities have revealed that the bones of people from the Jomon period 3000 years ago, which were kept by Kyoto University, are left behind after being bitten by sharks.
The group claims that it is the oldest bone ever for a person who has been attacked by a shark.
After being bitten by a shark, I found a human bone that was excavated about 100 years ago and kept by Kyoto University at the Jomon period ruins in Kasaoka City, Okayama Prefecture.
The bones are believed to belong to a middle-aged man from the Jomon period about 3000 years ago, and it was confirmed that there were about 800 wounds on the whole body, except for the right foot and left hand.
When a British graduate student focused on these scratches and investigated them in detail by research groups such as Kyoto University, the scratches were left in parallel as if they were scratched, and they all looked like V-shaped grooves. It means that the characteristics match those after the shark bites.
The oldest human bones found in Puerto Rico, about 1000 years ago, have been considered to be the oldest bones of people who have been attacked by sharks, but this discovery goes back about 2000 years. It means that it will be.
Professor Masato Nakatsukasa of Kyoto University, who conducted the research, said that it was estimated that the shark attacked a large shark with a body length of 4 meters or more, and that it was thought to be a great white shark or a tiger shark based on the sea environment around Japan at that time. "From the ruins of the Jomon era, historical materials showing the relationship between people and the sea at that time, such as excavated fishing needles and tiger sharks, have been found, but new discoveries different from those may lead to new findings in the future. I don't know. "
