古生物學家認為 Patagotitan mayorum (學名) 是一種巨型食草動物，屬於泰坦龍類，體重約為 70 噸。該物種大約在 100 到 9500 萬年前的白堊紀晚期生活在今天 Patagonian 的森林中，是迄今為止發現的最大的恐龍之一。
Paleontologists suggest that Patagotitan mayorum, a giant herbivore that belongs to a group known as titanosaurs, weighed in at around 70 tons. The species lived in the forests of today’s Patagonia about 100 to 95 million years ago, during the Late Cretaceous period, and is one of the largest dinosaurs ever discovered.
