Timmy the tortoise dies aged 160

A tortoise who was a ship's mascot in the Crimean War has died at his Devon castle home at the age of 160. Timothy, who was first discovered on board a Portuguese vessel in 1854, was thought to be the country's oldest resident. He lived at Powderham Castle near Exeter and was owned by Lady Gabrielle Courtenay, 91. He arrived there fully-grown in the late 19th Century. The castle's Rose Garden had been his home since 1935. He was also believed to be the oldest Mediterranean Spur Thighed Tortoise in existence.
