“the research team estimated that the dinosaur would have weighed 27 metric tons—about the same as nine adult Asian elephants—and measured 27 meters in length.”
SINGLE SOURCE
One source mentions Nagatitan weighed 30 tons and was over 88 feet long (approx 26.8m), which is very close to the claim's 27 tons/27 meters, but the specific 'nine adult Asian elephants' comparison is not corroborated by a second independent source.
