(Newser) – The death of a 9-day-old baby gorilla at Lincoln Park Zoo in Chicago has left authorities scratching their heads, the Christian Science Monitor reports. Yesterday, first-time mom Bana carried her baby's lifeless body to the zoo's gorilla enclosure, but zoo officials couldn't spot any serious wounds. "There are no bite marks or cuts and no sign of aggression, but it is possible she may have been dropped or even sat on," says a zoo spokesperson.

But life among gorillas can be dangerous. Last year, one family scuffle led to a baby gorilla losing part of a leg in Louisville, Kentucky. Earlier this year, an infant gorilla in London died during a group fight after a new male entered the group. In the wild, most gorilla infanticides happen when the dominant male dies, forcing moms to seek protection before another male murders her baby. As for Bana, zoo workers let her hold her baby for a few hours "to make peace with what happened." (For another ape story, read about the death of a chain-smoking chimp.)
