A 6,000 year old skull section from the town of Aitape located at Papua New Guinea almost certainly belonged to the fatality of a tsunami – an enormous, distressing ocean wave. Several researchers have analyzed the geological residue from the region where the mid-Holocene skull was actually found in the year 1929, and also found strong proof that it was swept by waves of tsunami – representing a probable cause of demise for the skull’s poor possessor. The skull was initially buried in a mangrove by Paul Hossfeld who is an Australian geologist. He regained it and took a field report of a area known as Paniri Creek, but didn’t test the residue in which it was buried.
Hence this is the reason why researchers travelled to Aitape. They stated that- “What we were doing was in fact going in and sampling the residue’s to bring back for lab investigation that would definitely let us know more about the period and depositional narration there.” The skull which was found has always been of great importance, as it’s one of the very few human being remains from region of that time. Earlier radiocarbon dating put its era for about 6,000 to 7,000 years old – at a point when ocean levels are high, and the area would have been nearer to the seashore.
It’s not recognized where, precisely, Hossfeld found the skull, but on the basis of his field description, the panel is fairly confident they were within 150 meters (329 feet) of its spot. When the panel investigated the residue, they found a huge number of residues from single-celled a marine organism which is known as diatoms. These microalgae are with this in a cell wall mainly built from silica, which remains at the back when the diatom dies. They are an excellent way for investigating ecological conditions, and (diatom) paleontology can help to rebuild sedimentary surroundings and precisely gauge the age of residue.
In the case, they can also help to settle on what actually happened in the region where it was found. “These residues that Aitape skull was in pure aquatic diatoms in them, which is deep-sea water that’s inundating it,” as stated by Golitko. “It’s actually high-energy deep-sea water – as high-energy sufficient for these small little specks of silica which are diatoms constructed to be broken as they are washing in.”
