Edmontosaurus annectens

Edmontosaurus annectens - Not really an easy meal for tyrannosaurs, despite the popular conception.


Temporal range: Late Cretaceous, Maastrichtian, ~67-65.5 Ma

Length: Around ~10-15 metres
Probable mass: Around ~5-15 tonnes?

Etymology: Connected Edmonton reptile


Edmontosaurus annectens is a species of titanic saurolophine hadrosaur that was one of the last non-avian dinosaurs to live before the KT extinction event. It has a long taxonomic history, in which specimens were assigned to several different genera over the years before they were finally grouped together as E. annectens. The adults of this species were once assigned to the now-synonymous Anatotitan copei (Cope's duck titan). E. annectens exhibits one of the most striking examples of the "duckbill" snout common to hadrosaurs.

It was a large megaherbivore, and would have competed with Triceratops and Torosaurus. Babies and juveniles would have been in danger of predation from dromaeosaurids and small-medium sized tyrannosaurs, but adult E. annectens were likely safe from any known North American Maastrichtian predator except Tyrannosaurus rex and probably Alamotyrannus. And even when against these titan tyrannosaurs, it was by no means defenceless, as large adult E. annectens grew much more massive and subsequently stronger than even the Tyrannosaurus specimen FMNH PR2081 (aka Sue), even rivalling Shantungosaurus giganteus in some cases. Like other hadrosaurs, it probably lived in vast herds.

First digitally-made large hadrosaur life restoration in my gallery. The postcranial body is mostly based on 's Edmontosaurus.

And yes, I gave it a WWD-Muttaburrasaurus-esque nasal resonation chamber. Because, why not? And you may notice the lack of a fleshy crest. The fleshy head crest is a feature of E. regalis, but probably not E. annectens, since the "Dakota" mummy doesn't seem to have it.
