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.

The animal belongs to a herd of hefty herbivores who spend their days lumbering through an open landscape of conifers and gingkos, horsetails and monkey puzzle trees.
