Mystery solve, and dating fossils
It took a bit of digging, but I found out why the domestic dog fossil found with the remains of the La Brea woman didn’t cause more of a sensation. Using carbon 14 dating, the dog fossil turned out to be around seven-thousand years younger than the fossil of the woman. What is carbon 14 dating, and how does it work?
Here’s a link to the paper about re-dating the remains of the La Brea woman, and the domesticated dog.
