Male mammoths more often fell into 'natural traps' and died, DNA evidence suggests

http://ift.tt/eA8V8J Researchers who have sexed 98 woolly mammoth specimens collected from various parts of Siberia have discovered that the fossilized remains more often came from males of the species than females. They speculate that this skewed sex ratio exists in the fossil record because inexperienced male mammoths more often traveled alone and got themselves killed by falling into natural traps that made their preservation more likely.
