Hello community In a scientific collection I was measuring some big cat skulls. In the collection, there is a really big jaguar and lion skull. I am curious about how big they could get, as I could not find any answer on the internet on this. Lion skull measures 42 cm (16,53 inch) long and 30 cm (11,8 inch) wide. It weights 3 kilograms. Jaguar skull measures 31 cm (12,2 inch) long and 19,5 com (7,68 inch) wide. It weights 1,2 kilograms and is so massive that a taxidermist thought it was a lion skull. Are these record measures of the respective species or have you heard of bigger jaguar or lion skulls?
