Ornithischia means ‘bird-hipped.’ This group is comprised mainly of plant eating dinosaurs. Although their pelves supposedly resembles that of birds, they have little else in common with birds (which are actually more closely related to the saurischian dinosaurs). A Harvard University study found that the genome for many of these animals is actually more like that of reptiles. Ornithischian dinosaurs came in all shapes and sizes, some quite ornate, while others were quite plain, they were bipedal, quadrupedal, and everything in between. Some had horns, some had crests and some were covered in bony armor. Ornithischians were the most diverse and abundant group of large animals on the planet, throughout the Mesozoic Era.
