(Give credit if you use) Torosaurus was a bulky herbivorous ceratopsian dinosaur related to Pachyrhinosaurus and Triceratops (according to some paleontologists, the two dinosaurs may be one and the same animal, with some sexual or chronological differences explaining the two different frills and other dissimilarities), but at about 9 meters (30 ft) in length and weighing an estimated 6-9 tonnes, it was smaller and lighter than Triceratops.
Thanks to WWD for the design and music. And thanks to walking with wikis for the text.
