The Giant Turtle
Archelon was a slow moving creature of the ancient seas
during the Cretaceous (65 to 146 million years ago). Some remains
measure over 15 feet long. Like many of today's turtles it ate
jellyfish and expired drifting fish as well as plants, buried its eggs in
sandy beaches, and may have lived more than 100 years.

skeleton of an Archelonnext to a standing man gives a perspective of the
size of these giant turtles
Giant Early Shark, Megalodon
was a prehistoric shark that lived roughly from 28 to 1.5 million years ago,
during the late Oligocene to early Pleistocene periods. Estimated to have
been over 50 feet long it was one of the largest and most powerful
vertebrate predators ever to have lived.
Meganeura monyi, Giant Dragonfly with a 29 Inch Wingspan
Meganeura monyi is a genus of extinct insects from the
Carboniferous period approximately 300 million years ago and are related to
the present-day dragonflies. They fed on other insects, and even small
amphibians. M. monyi is one of the largest known flying insect species ever.
Glyptodon was a huge armored mammal that
lived in South and North America during the Pleistocene (1.8 million to
11,000 years ago). Some were as long as 16 feet and would have weighed about
as much as a small car. They were related to modern day armadillos.
Glyptodon is believed to have been an herbivore, grazing on grasses and
Toxodons, named for the curvature of their
teeth, were a numerous species of mammal that lived in South America during
the Pliocene and Pleistocene epochs from about 2.6 million to 16,000 years
ago. Toxodons became extinct around the end of the Pleistocene. Some Toxodon
fossils have been found with arrow heads indicating that they were hunted by
humans who likely caused or contributed to their extinction.
Baluchitherium was an early hornless
rhinoceros which lived in Asia and fed on tree leaves during the late
Oligocene (24 to 38 million years ago ) and early Miocene (5 to 24 million
years ago). It was the largest known land mammal to have lived, estimated to
be 18 feet tall at the shoulder, 33 feet long and weighing more than 20
