Study: Male Woolly Mammoths More Often Fell into Natural Traps

An international team of researchers led by the Swedish Museum of Natural History has discovered that fossilized remains of woolly mammoths (Mammuthus primigenius) more often came from males than females (69% versus 31%). The scientists speculate that this skewed ratio exists in the fossil record because inexperienced male mammoths more …
