It’s finally clear who had the longest
More than 15 meters neck – it must have looked interesting with Mamenchisaurus sinocanadorum wagging its head. For comparison: That corresponds to the length of about six giraffes’ necks. However, the heads of the dinosaurs were surprisingly small.
Dhe dinosaurs may have a new record holder for neck length—at least for now. Researchers led by Andrew Moore from Stony Brook University in New York came to this conclusion, as reported by the British news agency PA. “With a length of 15 meters, it looks like Mamenchisaurus sinocanadorum will be the record holder – at least until something longer is discovered,” the paleontologist is quoted as saying. This corresponds to the length of about six giraffes’ necks.
The dinosaur species lived in what is now East Asia and other parts of the world more than 160 million years ago. Fossil remains of the animals were discovered in China in 1987. Although only a small number of bones were found, researchers have now been able to reconstruct the size and appearance of Mamenchisaurus sinocanadorum using complete skeletons of closely related dinosaurs. The extremely long neck made up about half of the total length of the animals. Their skull was very small in relation to their body.
Using computed tomography, the scientists discovered that the giants, like many birds, had hollow vertebrae. The animals also had neck ribs about four meters long, which provided stability – but also made the neck rather immobile. How giraffes According to the assumptions of researchers, the dinosaurs could not raise it up.
The new findings on the dinosaur are in the Journal of Systematic Palaeontology published.
