 "Diplodocus" has been a famous and much-depicted dinosaur as it has been on display in more places than any other sauropod dinosaur.Much of this has probably been due to its wealth of skeletal remains and former status as the longest dinosaur.The donation of many mounted skeletal casts of "Dippy" by industrialist Andrew Carnegie to potentates around the world at the beginning of the 20th century did much to familiarize it to people worldwide.
