The American woman who was mauled to death by a lioness in South Africa's Lion Park on Monday has been identified as Katherine Chappell, a visual-effects editor who has also worked on the hit TV series "Game of Thrones". 

Chappell, 29, was killed when a lion pounced through the open window of her car while she was taking pictures of the animal. The rules at the park prohibit keeping car windows open.  

She was in South Africa to raise money for an organisation working to protect animals from poachers. 

Chappell's sister posted a message on Facebook, mourning her death.

"We are broken-hearted to share this news with our friends and family: Yesterday morning, while on a volunteer mission to protect wildlife in South Africa, Kate Chappell was involved in a tragic and fatal accident.

"Katie was a brilliant, kind, adventurous and high-spirited woman. Her energy and passion could not be contained by mere continents or oceans. She was very much loved and shared her love for life with those she met.

"We cannot thank everyone enough for the kind words and support. It means the world to us during this difficult time."

Chappell had worked on "Godzilla" and "Captain America," and was part of an Emmy-winning episode of "Game of Thrones", a photo of which she had shared on her Instagram account.
