Woolly mammoths had sex on the brain.
Woolly mammoths had an enormous sex drive
Analysis of 30,000-year-old tusks from the extinct beasts have revealed that the mammoths experienced an enormous surge in testosterone during the mating season.
Scientists have drawn parallels with the woolly mammoths and elephants - as dribbling urine and huge hormonal surges are key signs that the large mammals are ready to mate.
This state is known as 'musth', which comes from the Hindi word for intoxicated and marks a period of frantic sexual excitement and aggression.
Michael Cherney, a researcher at the University of Michigan, told MailOnline: "For the first time, we can see these testosterone surges in an extinct species of elephant, the woolly mammoth.
"This might be as close as we're going to get to having direct evidence that these ice-age animals experience the entire suite of attributes that we associate with musth, including aggressive behaviour, dribbling urine, secretions from the temporal gland behind the eye, and even a change in posture and how they walk."
