Maiasaura is a characteristic fossil of the middle portion (lithofacies 4) of the Two Medicine Formation, dated from about 86.3 to 70.6 million years ago. [2] Maiasaura lived alongside the troodontids Stenonychosaurus and Troodon and the basal ornithopod Orodromeus, as well as the dromaeosaurid Bambiraptor and the tyrannosaur Daspletosaurus. [2]
Parasaurolophus, a crested hadrosaur.. Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores.The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.
Horner and others studied the histology of Maiasaura peeblesorum bones. They found that Maiasaura only took 8–10 years to reach adult body size. A 7 metres (23 ft) adult Maiasaura could have an adult body mass of over 2,000 kilograms (4,400 lb) despite hatching at a length of about half a meter and with a body mass of less than a kilogram ...
A nearly identical EQ range of 2.3 to 3.8 was found, and it was again noted this was higher than that of living reptiles, sauropods and other ornithischians, but different EQ estimates for theropods were cited, placing the hadrosaur numbers significantly below even more basal theropods like Ceratosaurus (with an EQ range of 3.31 to 5.07) and ...
Size compared to a human. Maip is estimated to have been around 9–10 metres (30–33 ft) long in life. As such, it may be the largest megaraptorid currently known. Members of the Megaraptoridae as a whole increased in body length following the extinction of the carcharodontosaurids in the Southern Hemisphere in the early Late Cretaceous. [4]
