Mount Vesuvius erupted in 79 AD , spewing molten rock, pumice, and hot ash over cities of Pompeii and Herculaneum .

The vast majority of victims died of asphyxiation, choking to death on thick clouds of noxious gas and ash.

A 2001 study in Nature estimated a temperature of 500 Celsius ( 932 Fahrenheit ) for the pyroclastic surge that destroyed Pompeii , sufficient to kill inhabitants in fractions of a second .

Scientists have found glass-like fragments of the guardian's brain at Herculaneum .

They say Vesuvius erupted in a hot ash cloud that surrounded its victims, including the guardian.

The ash cloud likely vaporized the soft tissues of other victims.

Once ash cloud dissipated, temperatures returned to ambient conditions, resulting in cooling.
