Longest dinosaur track found to be of 35-metre-long sauropod
The world's longest dinosaur tracks discovered in 2009 in a French village have been found to be part of a 110-step trackway extending over 155 metres. Researchers estimate the 150-million-year-old tracks were left by a 35-metre-long sauropod weighing at least 35 tonnes. While each footprint is about a metre long, it can reach three metres when including the displaced mud.
