Chinese scientists have discovered a block of sandstone three meters square that has more than 215 fossilized eggs. The eggs are from one species of flying reptiles known as Hamipterus tianshanensis–a pterosaur from the Cretaceous geological period. When scientists find that many eggs in one place, they can establish a great many facts about how the animals reproduced and lived. There is no question about the arrangement of the bones or how they developed.
We have suggested that dinosaurs had a very large role in the development of the resources on Earth that humans would eventually need. Knowing how these animals lived, what they ate, how they got around, and how they interacted with their environment helps us understand that role. In this case, the eggs contain at least 16 embryos for study.
The flying reptiles didn’t have the limitations of restricted mobility that other animals had, so they are of special interest to many paleontologists. Using computerized tomography (CT) scanning, they can see the embryos in three dimensions. Science can tell us much about the history of creation, and the pterosaur is just one part of that picture. We remind ourselves again that can know there is a God by the amazing things He has made.

Scientists have difficulty finding information about dinosaurs. Much of what we know about them has come from indirect information. I spent a great deal of time studying coprolite, which is petrified dinosaur droppings. By analyzing the solid wastes left by a dinosaur, we can tell what the animal ate. Sometimes we find plant materials–leaves, stems, seeds, etc. Sometimes it’s animal remains–teeth, bone fragments, and complete bones. It is extraordinarily rare to find a complete skeleton of a dinosaur, but now we have something even better.
Until recently we had never found an animal with skin in place and internal organs visible. In 2011 miners working in northern Alberta came across an amazing find that has given scientists their first complete mummy of a dinosaur. This dinosaur was a plant-eating nodosaurus, which means “knobbed lizard.” This animal is complete with its armor, spiky skin, and internal organs. Paleontologists have spent some 7,000 hours carefully extracting the creature. Caleb Brown, who is a researcher on the project, said, “We don’t just have a skeleton, we have a dinosaur as it would have been.”
Dinosaurs were the agents that prepared Earth for humans. Without that preparation, we would not be able to have our crops, our domesticated animals, and our advanced civilization. Dinos were key agents in preparing an ecosystem suitable for us. They lived in an environment very unlike what we have on Earth today. Having a find like this will greatly enhance our understanding of Earth’s history.
It is clear that God used natural processes to prepare the planet for us, and the dinosaurs played an important part in that process. Scientists will continue to study this dinosaur, and in the process, we will learn more about God’s wisdom in design.
