Many plant, butterfly, and dinosaur secrets remain hidden in fossils and rocks waiting to be found, maybe by you.

DAYS OF THE DINOSAURS

Big Birds

Pterosaurs, with wings 40 feet wide. lived at the time of the dinosaurs. They were not dinosaurs but giant flying reptiles.

Fancy Feathers

Scientists believe that some dinosaurs had feathers. They recently discovered the fossil of a baby T. rex with feathers. Scientists believe that the feathers helped keep the young Tyrannosaurus warm and may have fallen out as it got older.

Dinosaur Mom

The dinosaur Maiasaura scooped out a nest 7 feet wide to hold the 25 grapefruit-sized eggs it laid. They were carefully arranged in circles and covered with vegetation to keep them warm until they hatched.

Sowing Seeds

A plant starts as a seed. The seed sprouts and grows into a plant. The mature plant produces seeds to start the cycle of life again.

Eager Eaters

Caterpillars spend much of their time eating, until they form a chrysalis and wait to be born as a butterfly.

Bunches of Bugs

Insects make up 80 percent of all creatures on Earth. More than one million kinds of insects have been discovered so far. Insects eat 20 percent of Earth’s vegetation each year.

Dangerous Diet

Some caterpillars eat the leaves of poisonous plants but are not harmed. When these caterpillars become butterflies, their colorful wings are a signal to predators that eating them is a very bad idea.
