- One other abelisaurid, Niebla, was present in Argentina with extra typical theropod jaw than later abelisaurids supply
- A brand new small tyrannosauroid from China, Jinbeisaurus, helps that the primary large tyrannosaurs have been in North America supply

- Small and gracile
- Estimated to be about 15 ft (4.5 m) lengthy and weigh between 500 and 1,000 lb (227 to 454 kg)

- Holotype is presumably a juvenile, UMNH VP 20208, and features a practically full cranium, dentary enamel, vertebrae, proper humerus, proper scapula, left ischium, proper tibia, proper femur, and left metatarsals (had a big orbital within the cranium)
- In all probability seemed like different iguanodonts, with a cumbersome physique

- A part of the sub group Styracosterna
- Closest relative is Theiophytalia, an iguanodontian
- Helped present that Early Cretaceous iguanodonts in North America have been extra primitive than iguanodonts in Europe and Asia that lived on the similar time
- Lived round small lakes with gradual transferring rivers, in an space with a seasonally dry local weather
- Different dinosaurs that lived on the similar time and place embrace Iguanacolossus (one other ornithopod), ornithopod Cedrorestes, sauropods Cedarosaurus and Moabosaurus, theropods Martharaptor and Nedcolbertia, nodosaurid Gastonia, and dromaeosaurid Utahraptor
