Life restorations are artistic reconstructions based on fossil evidence; true coloration and soft-tissue details remain uncertain.
Carnotaurus
Carnotaurus sastrei (Carnotaurus · カルノタウルス)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 An estimated body length of about 8 m (representative value for the genus) is just short of the length of two passenger cars (about 4.5 m each) (Comparison).
- 💡 The "bull" in its name comes from the two horns on its head, and its tiny arms are seen as a vestige of longer ancestral forelimbs.
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.
📖 1. Overview
Carnotaurus sastrei (genus Carnotaurus) was a carnivorous theropod that lived in Argentina during the Late Cretaceous and is the only dinosaur in the abelisaurid group with two horns on its head. Its name means "meat-eating bull."
🦴 2. Anatomy & Morphology
It had two horns on its head, a very short snout, and extremely small arms. Skin fossils show scales with no evidence of feathers, and its lower jaw was flexible.
🔍 3. Fossil Record & Paleoecology
It is thought to have hunted large sauropods, and recent studies suggest its bite force may have been stronger than that of an American alligator. Uses of the horns are only estimated to include fighting, hunting, attracting mates, or recognizing members of its own kind.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
