The official Communist Party newspaper in China is claimed the snake was one of two enormous boas found by workers clearing forest for a new road outside Guping city, Jiangxi province.
They apparently woke up the sleeping snakes during attempts to bulldoze a huge mound of earth.
“On the third dig, the operator found there was blood amongst the soil, and with a further dig, a dying snake appeared,” said the post.
“At the same time, another gold colored giant boa appeared with its mouth wide open. The driver was paralyzed with fear, while the other workers ran for their lives.
“By the time the workers came back, the wounded boa had died, while the other snake had disappeared. The bulldozer operator was so sick that he couldn’t even stand up.”
The post claimed that the digger driver was so traumatized that he suffered a heart attack on his way to hospital and later died.
The dead snake was 55ft (16.7m) long, weighed 300kg and was estimated to be 140 years old, according to the post.
