A dentist caught a 抱擁する surprise when he visited his parents' house and spotted a familiar bit of anatomy embedded into the 回廊(地帯) of their newly renovated home.
The freshly laid tile appeared to 含む/封じ込める a human jawbone, just inside the threshold that leads out to the terrace, によれば a 地位,任命する on Reddit where he 株d the find.
Reddit is rife with 偽の 地位,任命するs, but 多重の 専門家s 確認するd to DailyMail.com that this really does appear to be a jawbone, and that it probably belonged to either a modern human (Homo sapiens) or, more likely, an extinct hominin like Homo erectus or a Neanderthal.
And if the 化石 belonged to one of these?古代の human ancestors, it is anywhere from 24 thousand to 1.9 million years old.
A Reddit 使用者 地位,任命するd this photo of a jawbone 設立する in his parent's home. It was embedded into a travertine tile. Travertine is a 激しく揺する that 一般的に 含む/封じ込めるs 化石s.
Neither Killgrove nor Corthals could say for sure what 肉親,親類d of hominin 種類 the jaw belonged to, but Corthals had some ideas.
'The mandible is 公正に/かなり 狭くする. It could be a human, but it looks more like a hominin,' she said.
'There's been 化石s of Homo erectus and Homo heidelbergensis excavated from this type of 石/投石する before. It could be Neanderthals, it could be anything. Any of the hominins,' Corthals 追加するd.
The tile was quarried in Turkey, Kidipadeli75 wrote, and Corthals 確認するd that travertine quarries in Turkey have been the 場所/位置 of 多重の hominin finds.
Because of the angle the jawbone was 削減(する) to make the tile, it may also be difficult for a paleontologist to identify who the tile (機の)カム from.
Some 手がかり(を与える) s are there, though, Corthals said.
She pointed out the alveolar 過程, the 厚い 山の尾根 of bone that 持つ/拘留するs the tooth sockets.
At Mammoth Springs in Yellowstone 国家の Park, you can see travertine 存在 formed in real time, as calcium-rich water precipitates its minerals の上に the surface.
The jawbone in the travertine tile, shown here with a 白人指導者べったりの東洋人 for 規模. The redditor's parents did not notice it until he pointed it out.
In modern humans, this section of bone is not very long 前線 to 支援する. But in this jawbone, it has a large 量 of 構成要素 behind the 前線 teeth.
This thickness is more characteristic of Homo erectus mandible anatomy.
'My money is on Homo erectus,' Corthals said. 'There is much more space there than on Homo sapiens.'
The 全体にわたる width of the mandible, too, looks more like Homo erectus than Homo sapiens, she 追加するd.
If the jawbone belonged to a Neanderthal, it could be between 200 thousand and 24 thousand years old. And if it belonged to a member of Homo erectus, it could be between 1.9 million and 108 thousand years old.
Jawbones tend to be 比較して 壊れやすい, Corthals pointed out, so the fact that it's 損なわれていない 示唆するs it was probably fossilized before it got embedded into the travertine.
And since fossilization can take a long time, the jawbone is also probably 極端に old, she said, making it ありそうもない that it belonged to a modern human.
So this newly tiled home is probably not a 罪,犯罪 scene, fortunately. But it is やめる a find.?
