I mean, here's Edmontosaurus and Anatotitan.
Edmontosaurus was widely distributed across western North America.
They found four classes of scratches on Edmontosaurus teeth.
Edmontosaurus has been described in detail from numerous specimens.
First, the specimen is actually of Edmontosaurus annectens.
Edmontosaurus was a wide-ranging genus in both time and space.
The episode then cuts to the high Arctic, where Edmontosaurus are hunted by a large species of Troodon.
Edmontosaurus has been considered a possibly migratory hadrosaurid by some authors.
The time span and geographic range of Edmontosaurus overlapped with Tyrannosaurus, and an adult specimen of E.
As many as three quarters of the dinosaur specimens from badlands near Drumheller,Alberta may pertain to Edmontosaurus.[87].
Two known species: Edmontosaurus regalis and Edmontosaurus annectens.
Like Stegosaurus, the neural canal was expanded in the hips, but not to the same degree: the endosacral space of Stegosaurus had 20 times the volume of its endocranial cast,whereas the endosacral space of Edmontosaurus was only 2.59 times larger in volume.
Fossils of Edmontosaurus discovered in eastern Montana(Hell Creek Formation).
Before the 1960s and 1970s, the prevailing interpretation of hadrosaurids like Edmontosaurus was that they were aquatic and fed on aquatic plants.
The bone histology tells us that Edmontosaurus is a juvenile, or at least a subadult, and the other one is an adult, and we have an ontogeny.
However, the most recent review of Hadrosauridae, by Jack Horner and colleagues(2004),came to a noticeably different result: Edmontosaurus was nested between Gryposaurus and the"brachylophosaurs", and distant from Saurolophus.
Edmontosaurus has had a long and complicated history in paleontology, having spent decades with various species classified in other genera.
Research conducted by computer modeling in 2007 suggests that Edmontosaurus could run at high speeds, perhaps up to 45 kilometres per hour(28 mph).
Edmontosaurus regalis is known from the lowest of five units within the Horseshoe Canyon Formation, but is absent from at least the second to the top.
The fact that the damage seems to have healed suggests that the Edmontosaurus survived a tyrannosaur's attack on a living target, i.e. the tyrannosaur had attempted active predation.
Although Edmontosaurus was only named in 1917, its oldest well-supported species(E. annectens) was named in 1892 as a species of Claosaurus, and scrappier fossils that may belong to it were described as long ago as 1871.
A 2007 study by Terry Gates andScott Sampson found broadly similar results, in that Edmontosaurus remained close to Saurolophus and Prosaurolophus and distant from Gryposaurus, Brachylophosaurus, and Maiasaura.
Although Edmontosaurus was only named in 1917, its oldest well-supported species(E. annectens) was named in 1892 as a species of Claosaurus.
Two specimens still under study in the collection of the Museum of the Rockies- a 7.6 m(25 ft) tail labelled as MOR 1142 and another labelled as MOR 1609-indicate that Edmontosaurus annectens could have grown to larger sizes, possibly rivaling Shantungosaurus in size.
The reconstruction of Edmontosaurus annectens, a plant-eating hadrosaur was based on a juvenile specimen, but still weighed in at between 0.8? 0.95 tonnes.
Traditionally, E. regalis has been regarded as the largest species, though this was challenged by the hypothesis that the largerhadrosaurid Anatotitan copei is a synonym of Edmontosaurus annectens, as put forward by Jack Horner and colleagues in 2004, and supported in studies by Campione and Evens in 2009 and 2011.
The time span and geographic range of Edmontosaurus overlapped with Tyrannosaurus, and an adult specimen of E. annectens on display in the Denver Museum of Nature and Science shows evidence of a theropod bite in the tail.
Edmontosaurus was also reported from the Javelina Formation of Big Bend National Park, western Texas based on TMM 41442-1, but was later referred to Kritosaurus cf. navajovius by Wagner(2001), before being assigned to Kritosaurus sp. by Lehman et al.(2016).
A study published in 2008 by Casey Holliday andLawrence Witmer found that ornithopods like Edmontosaurus lacked the types of skull joints seen in those modern animals that are known to have kinetic skulls(skulls that permit motion between their constituent bones), such as squamates and birds.
Their results showed that within both recognized Edmontosaurus species, many features previously used to classify additional species or genera were directly correlated with skull size.
