The Jurassic Period of the Mesozoic Era spanned 50 million years from
199.6 to 145.5 million years ago.
It is the second period of the Mesozoic Era following the Triassic Period.
In this period, giant reptiles such as dinosaurs thrived on the land,
and ammonites, in the sea.
In the latter part of the Jurassic Period, birds appeared for the first time,
with gymnosperms like cycads and gingkoes thriving.

legs to reach and feed on the leaves of tall trees.
Its most prominent body feature is the oval-shaped dermal scutes on both
its back and tail.
It was discovered both in the
U.K. and
U.S.A.

Early Jurassic, it had two crests split in the shape of a V on
top of its head.
Its razor-sharp teeth, long and strong legs, and long claws were
perfect for hunting.
Its first toe on its hand was shaped in the way to hold a prey,
functioning like a thumb.
