Mammoth Brains
One of the strangest, yet most scientifically significant, discoveries was a completely preserved mammoth brain found on the coast of the Laptev Sea. The brain was in the same place as other remains from the same mammoth, including tusks legs, yet no torso was found. This discovery led scientists to deduce that the average lifespan of a woolly mammoth around 60 years, as opposed to the formerly presumed 6-10 years.
