The Edmontosaurus, another herbivore, roamed the forests like the Pachyrhinosaurus - and is helping palaeontologists build up a picture of this ancient land.

The dinosaurs included carnivorous megalosaurs - ancestors of Tyrannosaurus rex - and long necked herbivores that were up to three times bigger in size than an elephant.

Meanwhile, the Stegosaurus is seen an iconic herbivore, whose armored plates and spiked tail helped it to defend itself against predators and adapt to a challenging environment.

The palaeontologists hypothesise that charcoal was ingested to detoxify stomach contents, as ferns can be toxic to herbivores.

In the late Jurassic, the climate grew warmer and more humid, and vegetation expanded, providing more food for dinosaur herbivores such as sauropods, the iconic long-necked behemoths, who left behind dung full of plant remains.
