One of those surprising fossil beds is a place called Dinosaur Cove, Australia. One hundred million years ago, Australia was connected to Antarctica. Both continents were located near the South Pole. Today, paleontologists dig dinosaur fossils out of the ground. They think about what those ancient bones must mean. What was the climate like at Dinosaur Cove then? It was cold! The average temperature was probably around 30 degrees F. The weather would have been like the weather in southern Alaska.

How does the author tell about the climate of Dinosaur Cove?

• by explaining how dinosaurs had to adapt

• by comparing it to the weather of Alaska

• by identifying differences between its location then and now

• by describing the amount of daylight during different seasons

If reptiles get too cold, they become sluggish and slow. Some paleontologists wonder if maybe dinosaurs were more like birds than reptiles. If dinosaurs were “warm-blooded” like birds, then they could have made their own heat. That would explain how dinosaurs might have survived through the cold, dark winters at Dinosaur Cove.

How does the author explain the effect of living at Dinosaur Cove on the dinosaurs?

• by showing that dinosaur fossils were found there by paleontologists

• by showing that dinosaurs of Dinosaur Cove lived on a peninsula and could not migrate

• by describing that dinosaurs were like birds than reptiles

• by describing that dinosaurs of Dinosaur Cove were the last dinosaurs on Earth

To survive, these dinosaurs had to adapt. Imagine you are a dinosaur at Dinosaur Cove. If you happen to have larger eyes, you will have a better chance of surviving than will a dinosaur with small eyes because you can see in the dark. Your children will probably have big eyes, too. As time goes by, there will be more and more dinosaurs with bigger eyes. Big eyes helped the dinosaurs see evergreen trees in the darkness. Since these trees didn’t lose their needles in the winter, they were food for the plant-eating dinosaurs. Big eyes also helped the dinosaurs watch out for predators that would have hunted them.

Which statement from the text explains what helped dinosaurs stay alive in the darkness?

• “In other parts of the world, dinosaurs probably migrated away from the winter’s darkness.”

• “Since these trees didn’t lose their needles in the winter, they were food for the plant-eating dinosaurs.”

• “If dinosaurs were ‘warm-blooded’ like birds, then they could have made their own heat.”

• “Big eyes also helped the dinosaurs watch out for predators that would have hunted them.”

But what if some dinosaurs could survive cold polar winters? Could they also survive on a colder planet? What if the descendents of the animals at Dinosaur Cove survived the extinction? Could they have been the last dinosaurs on Earth? The wonderful thing about science is that each new answer creates more questions. Maybe one day you will become a paleontologist and travel to the coldest parts of the world to search for the bones of Earth’s last dinosaurs. Be sure to pack a sweater!

What word could be used in place of the word "descendents?"

• relatives

• families

• reptiles

• birds
