TRIASSIC Period
Triassic period is characterized by the rise of the dinosaurs, turtles, crocodiles, and frogs. It is also the first phase of the Mesozoic era which is called the age of the dinosaurs. It spanned a time frame about 248- 208 million years ago. -
PLATEOSAURUS

Archaeopteryx is believed to be the earliest known bird. It is actually considered to be the intermediate between the birds and predatory dinosaurs, a possible link between reptiles and birds. -
Creataceous 145 to 65 million years ago
The Cretaceous period began about 145 million years ago and ended 65 million years ago with the extinction of the dinosaurs. Flowering plants and modern insects appeared. Dinosaurs of all shapes and sizes walked the land, including duckbills, armored, horned, and dome-headed dinosaurs. -
TRICERATOPS prorsus
Triceratops was the most numerous of the horned cretaceous dinosaurs as well as the largest ceratopsian; it was one of the last to become extinct. Its name means "three horned face". Triceratops was a herbivore and its largest predator was Tyrannosaurus rex. -
PTERANODON
This extinct flying reptile was a pterosaur, descendant of the
