DescriptionAt 4-4.5 m (12-16 ft) long and 1.5 m (4 ft) high at the hip, Rugops was a midsize carnivore. The skull bore armour or scales, and other bones had many blood vessels, causing Dr. Paul Sereno, who led the team that discovered the fossil, to say, “It’s not the kind of head designed for fighting or bone-crushing”, suggesting that it may have been mostly a scavenger (though this has yet to fully be confirmed). The skull also bears two rows of seven holes each, of unknown purpose, although Sereno has speculated that they may have anchored some kind of crest or horns. Like other abelisaurs, Rugops probably had very short arms. These were probably useless in fighting. They may have only been balance tools, items to counterbalance the dinosaur’s head. The type species is R. primus (meaning “first wrinkle-face”). Rugops is believed to be an abelisaurid, related to other abelisaurids like Majungasaurus and Carnotaurus. The discovery of the related genus Chenanisaurus indicates African abelisaurids such as Rugops may have been distinct from other abelisaurids in Gondwana.
In the media
- Rugops appears in the third episode of Monsters Resurrected Biggest Killer Dino, attacking a juvenile Paralititan but inaccurately shown it being lifted by the jaws of Spinosaurus and gobbled up whole. In real life, a 30 ft long Rugops was far too large for Spinosaurus to lift with its 5.5 ft (1.7 meter) long jaws and consume whole. The other one was being chased by the Spinosaurus but was killed. Then a pack of 5 Rugops took down a Paralititan before having a Spinosaurus attempt to steal the food, but the pack's numbers are so great, the theropods kill and eat the Spinosaurus after it fell on it's side & broke it's tall spines.
- Rugops also appears in BBC's Planet Dinosaur, where it was shown as a scavenger, eating the remains of the dead 8 m (27 ft) sawfish Onchopristis left by a Spinosaurus.
- Rugops DNA was used in order to help make the Indominus rex in Jurassic World by adding neck armour to it.
- This dinosaur was one of the supporting characters (identified in 2016) in Ricardo Delgado's Age of Reptiles: Ancient Egyptians mini-series.
