Dinosaur Babies
Read and answer : Can people see a real dinosaur in the wild now?
When people are talking about finding dinosaur bones today, they are finding fossils.
Fossils can tell us about dinosaur eggs, dinosaur nests, and dinosaur babies.
Dinosaur eggs are usually found in nests. But dinosaur nests are not like the ones birds build in trees. Most dinosaur nests were dug in sand and mud.
Scientists say that some dinosaurs returned to the same nesting grounds year after year.
The biggest dinosaur egg fossils ever found are about the size of a football. But the mother dinosaur that laid them was over 40 feet long!
Why did huge dinosaurs lay small eggs? Scientists think that if dinosaur eggs had been bigger, the shells would have been too thick for baby dinosaurs to break out of.
After coming out from the eggs, dinosaur babies grew bigger and bigger, stronger and stronger, and tried to survive in that tough world.
