Sauropods are dinosaurs known for their towering long necks and huge bodies, and in a new study, scientists have found a sauropod with the longest neck of them all.
The Late Jurassic Chinese sauropod Mamenchisaurus sinocanadorum had a 50-foot-long neck, according to estimations from Stony Brook researcher Andrew J. Moore and his team’s analysis published in the Journal of Systematic Palaeontology. This is the longest neck discovered on any dinosaur–or any animal–yet, comparable to the height of a four-story building or eight giraffe necks stacked on top of each other.
The Mamenchisaurus at the center of the study was first discovered in 1987 from 162-million-year-old rocks in northwest China. Due to the partial nature of the remains, Moore and his team reconstructed the Mamenchiasaurus’ evolutionary relationships and were able to use close relatives, like the Xinjiangtitan shanshanesis (a specimen with a remarkably well-preserved neck), to estimate the Mamenchiasaurus’ neck length.
