Carnotaurus was a large theropod, about 8 metres (26 ft) in length, weighing between 1488 kg and 2626 kg (1.6–2.9 short tons),
depending on the method of estimation. The most distinctive features of Carnotaurus are the two thick horns above the eyes,
and the extremely reduced forelimbs with four basic digits, though only the middle two of these ended in finger bones,
while the fourth was splint-like and may have represented an external 'spur.' The fingers themselves were fused and immobile,
and lacked claws. It is also characterized by its unusually long neck (compared to other abelisaurs), and its small head
with box-shaped jaws. The eyes of Carnotaurus faced forward, which is unusual in a dinosaur, and may indicate binocular vision and depth perception.
