A dinosaur which roamed components of the world 160 million years in the past is assumed to have had the longest neck ever seen in an animal, based on scientists.
Known as Mamenchisaurus sinocanadorum, the dinosaur’s neck measured 15.1 metres – six occasions longer than the necks of giraffes and 1.5 occasions the size of a double-decker bus.
The animal belongs to a subgroup of dinosaurs often called sauropods, that are recognized for his or her giant measurement, lengthy neck and tail, four-legged stance and plant-eating weight loss plan.
Dippy – the well-known dinosaur on show on the Natural History Museum in London – belongs to this group.
Dr Andrew J Moore, a palaeontologist at Stony Brook University, New York, mentioned: “With a 15-metre-long neck, it looks like Mamenchisaurus sinocanadorum might be a record-holder – at least until something longer is discovered.”
The M. sinocanadorum roamed east Asia and its fossils have been first found in China in 1987 inside 162-million-year-old rocks.
Dr Moore and his colleagues re-examined the specimens as a part of their analysis into the dinosaurs.
Although M. sinocanadorum is understood solely from a handful of bones from the neck and cranium, scientists have been in a position to reconstruct its measurement and form with assist from full skeletons of its closest kinfolk.
Dr Moore mentioned: “All sauropods have been massive however jaw-droppingly lengthy necks did not evolve simply as soon as.
“Mamenchisaurids are important because they pushed the limits on how long a neck can be and were the first lineage of sauropods to do so.”
The paleontologists used a way often called computed-tomography scanning which revealed the vertebrae – again bones – of M. sinocanadorum have been light-weight and hole with air areas taking over almost three-quarters of the amount.

According to the researchers, a lot of these bones are often seen in small birds.
To compensate for its light-weight bones, M. sinocanadorum had rod-like ribs within the neck about 4 metres lengthy to assist with its stability, the crew mentioned.
The largest dinosaur to have lived was the Patagotitan mayorum, which was regarded as 37.5 metres lengthy and weighed about 57 tonnes.
The analysis is printed within the Journal of Systematic Palaeontology.
