Other Prehistoric Life

Dinosaurs weren't the only creatures roaming the earth tens of millions of years ago. Here's a look at the other flora and fauna of the Triassic, Jurassic and Cretaceous Eras, including insects, plants, and aquatic and land animals.
Prehistoric Whales - The Story of Cetacean Evolution
It may be hard to believe, but modern whales evolved from terrestrial, dog-sized mammals that roamed central Asia about 50 million years ago. Here's the story of cetacean evolution, along with profiles of a dozen prehistoric species.
Prehistoric Horses - The Story of Equine Evolution
Horses have come a long way since their tiny, ferret-sized ancestors prowled the woodlands of North America, 10 million years after the extinction of the dinosaurs. Here's a look at horse evolution, along with profiles of various prehistoric horse genuses.
Prehistoric Proboscids - Mammoths, Mastodons, and Early Elephants
Modern elephants belong to a long and distinguished evolutionary line that dates back 60 million years, to shortly after the extinction of the dinosaurs. Here's a brief history of prehistoric pachyderms, along with profiles of extinct species ranging from Amebelodon to Stegomastodon.
Saber-Toothed Cats - The "Tigers" of the Prehistoric Plains
They weren't technically tigers, but the saber-toothed cats were every bit as dangerous to the grazing mammals (and early hominids) of their day. Here's a look at saber-tooth evolution and lifestyles, and profiles of various genuses of saber-toothed cats.
Dino-WHAT? 10 Ancient Creatures That Grew to Dinosaur-Like Sizes
The Greek prefix "dino" (meaning "great" or "terrible") is extremely versatile--it can be attached to just about any kind of creature, as demonstrated by the examples below.
The First Mammals – Mammals of the Triassic, Jurassic and Cretaceous
It's not quite true that mammals succeeded the dinosaurs--they lived right alongside these lumbering beasts, in small, quivering, furry form, all through the Mesozoic Era. Here's a look at the evolution, anatomy and survival strategies of the early mammals of the Triassic, Jurassic and Cretaceous periods.
Trilobites: The Dinosaurs of the Arthropod Family
Millions of years before the dinosaurs, trilobites ruled the earth's oceans. Here's a brief description of these unique creatures, and why their fossils are so important to paleontologists.
