Patagotitan mayorum
读音： PAT-ah-go-TY-tan may-OR-um
Titanosauria
A giant titanosaur from the latest Early Cretaceous of Chubut, Argentina, known from at least six individuals in one quarry. Its describers estimated 69 tonnes; later work suggests 50 to 55 tonnes.

概览
此内容目前仅提供英文版。
Patagotitan mayorum lived in Patagonia about 101.6 million years ago, at the end of the Early Cretaceous. A farm worker found the first bone in 2010 on the La Flecha ranch in Chubut Province; teams from the Museo Paleontológico Egidio Feruglio excavated the quarry, and José Carballido and colleagues named it in 2017.
At least six individuals were found in the same quarry, so almost the whole skeleton is known from repeated bones. The holotype (MPEF-PV 3400) includes neck, back and tail vertebrae, the shoulder, both pubes and both femora.
From the size of its limb bones Carballido et al. estimated 69 tonnes (with a standard error of 17 tonnes). Gregory Paul (2019) found it lighter, about 50 to 55 tonnes, and smaller than Argentinosaurus. A cast of the skeleton is displayed at the American Museum of Natural History.
名称含义
From Patagonia and the Titans of Greek myth, "symbolic of strength and large size"; mayorum honours the Mayo family of the La Flecha ranch (Carballido et al. 2017).
生物学与证据
科学家对这种动物生活方式的看法，以及每种观点的证据有多充分。
社会生活
Several Patagotitan died at the same place on separate occasions.
证据等级：中等证据The six individuals lie in three separate horizons, so the site records repeated deaths rather than a single herd dying together.

标本 · Patagotitan multi-individual quarry
At least six individuals of similar size in one quarry, in three closely spaced horizons.
标本： MPEF-PV 3400
其他
Patagotitan weighed more than 50 tonnes.
证据等级：有力证据Two independent methods give 50 to 69 tonnes. Whether it was heavier than Argentinosaurus is disputed.

生物力学模型 · Patagotitan limb-scaling mass estimate
Femur and humerus circumferences give 69 t (standard error 17 t), about 15% more than Dreadnoughtus with the same equation.
标本： MPEF-PV 3400
生物力学模型 · Patagotitan volumetric mass estimate
A volumetric model gives 50-55 t, with dorsal vertebrae smaller than those of Argentinosaurus.
