Jurassic Swamp


Jurassic Swamp
200 to 145 million years ago Sea levels were higher during the Jurassic period. Some land got flooded, which created muddy swamps

During the late Jurassic period, the Earth’s temperatures had cooled to around 30°C (86°F), declining still further later on in the period, and the Earth began to experience seasonality, with extremely hot summers and unbearably cold winters. Nevertheless, the Jurassic period is when life on Earth thrived, with large dinosaurs roaming the land, huge reptiles dominating the seas and winged reptiles ruling the skies. The oceans were teeming with new predators, including ammonites, belemnites and a range of shell-crushing fish. One of the most formidable predators of this period was the Allosaurus. With a large skull full to the back with sharp, serrated teeth and three large claws on either hand that may have been used to grip onto its prey, many believe that the Allosaurus hunted stegosaurs, ornithopods and sauropods – creatures that devoured the plants native to the planet’s swamps. Stegosaurus is perhaps the bestknown stegosaur and was so-called because of the strange, diamond-shaped plates running down its back (Stegosaurus means ‘plated lizard’). While many assume that these plates were for defence, the two pairs of long spikes that projected from the tip of the tail were much more likely for this purpose, rendering the plates little more than fancy decorations.
