Podocnemididae

Fossils show that Podocnemidids were once found in Europe, Asia, North America, and Africa. Stupendemys lived around 5.5 million years ago in northern South America, and was the largest freshwater turtle with a carapace length of 2.4 metres, the largest of any known turtle and is the largest pleurodire known.[9]
