This is Lyuba, a female baby wooly mammoth that only lived 30 to 35 days.
She is believed to have died around 41,800 years ago and is considered to be the best preserved mammoth to ever be found. She was discovered by an indigenous hunter and reindeer herder named Yuri Khudi and his three sons on the bank of a frozen river in Siberia.
After running some tests, scientists concluded that the baby mammoth had been preserved in lactic acid that was produced by a bacterium that had entered her body shortly after death.
A CT scan revealed that she still retained her organs and her intestines showed traces of feces from an adult mammoth. Baby mammoths typically consume their mother’s feces in order to obtain the necessary microbes needed for their body to properly digest grᴀss. The scan also revealed her cause of death to be drowning in muddy water.
Lyuba was roughly the size of a large dog with a height of 33.5 in. (85 cm) and a length (trunk to tail) of 51 in. (130 cm). She weighed 110 lbs (50kg).
