Carnotaurus sastrei lived in Patagonia, Argentina, near the end of the Cretaceous. José Bonaparte found its single known skeleton in 1984 in the La Colonia Formation of Chubut Province and named it in 1985.
It had a short, deep skull with a pair of thick horns above the eyes, and arms even more reduced than those of T. rex, with stubby forearms. The skeleton was found with large areas of skin impressions: rows of big conical bumps among small scales, and no sign of feathers (Hendrickx & Bell 2021).
Its tail had very large muscle attachments, and Persons and Currie (2011) argued it was one of the fastest large theropods in a straight line, though not agile in turns. How it used its horns, and how it hunted, remain open questions.
名称含义
From Latin carnis ("flesh") and taurus ("bull"): "meat-eating bull", for its horns; sastrei honours Ángel Sastre, owner of the ranch where it was found (Bonaparte 1985).
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。
运动方式
Carnotaurus was a fast runner in a straight line but not agile.
证据等级:中等证据Its tail had room for very large leg-retracting muscles, which suggests high speed. The same stiff tail would have made sharp turns difficult.

生物力学模型 · Carnotaurus tail muscle reconstruction
Reconstruction of the caudofemoralis muscle, very large thanks to wide tail ribs, the main muscle for pulling the leg back.
标本: MACN-CH 894
皮肤与体表覆盖
Carnotaurus had scaly skin with rows of large bumps and no feathers.
证据等级:直接证据Its only skeleton was found with large patches of skin impressions, showing small scales mixed with bigger cone-shaped ones on several parts of the body.

Skin from the neck, shoulder, chest and tail: small pebbly scales with scattered large conical scales, and no feathers.

行为
Carnotaurus used its horns in head-butting contests.
证据等级:假说Models show the skull could bear the loads of head-to-head shoving, but how the horns were used is not observed. Display is also possible.

生物力学模型 · Carnotaurus skull finite-element model
Stress model of the skull and jaws: a fast but relatively weak bite; the horns and skull roof can bear head-butting loads.
标本: MACN-CH 894
其他
The arms of Carnotaurus were vestigial and had little use.
证据等级:中等证据Its forearms are extremely short and its hands lack proper claws, so the arms were probably of little use for catching prey.
