DescriptionThough known only from a partial skull found in the Echkar Formation, Rugops was estimated as being {{convert|6|m|ft|1}} long and {{convert|750|kg|lb}} in weight based on comparisons with its relatives.[1] Later estimates suggest a revised length of {{convert|4.4|m|1}}.[2] At the same time other authors suggest that it measures {{convert|5.3|m|ft|1}} long and {{convert|410|kg|lb}} in weight.[3] Paul Sereno, who led the team that discovered the fossil, said "It's not the kind of head designed for fighting or bone-crushing", suggesting that it may have been a scavenger.{{Citation needed|date=September 2018}} The top of the skull bears two rows of seven holes, each of unknown purpose, although Sereno has speculated that they may have anchored some kind of display crest or horns; based on the presence of grooves for blood vessels forming a pathway into these pits.[4] Like other abelisaurs, Rugops likely had very short, or even vestigial arms. These were probably useless in fighting, and may have only been used to counterbalance the dinosaur's head.{{Citation needed|date=September 2018}} PaleoecologyThe discovery of Rugops See also{{Portal|Dinosaurs|Cretaceous|Paleontology|Prehistory of Africa}}
