Question
Sasha found a picture on a university website of a dinosaur’s eggs. This picture was made by a CT scanner. The scientists scanned the egg to see what was inside without damaging the outside of the fossil. The picture showed growth lines on the baby dinosaur's teeth. Scientists determined that the dinosaur formed one line each day it was in the egg. What information could Sasha determine from the CT scan of the dinosaur egg?
Answer
Sasha could determine the growth rate of the baby dinosaur while it was in the egg by counting the growth lines on its teeth, and how long the baby dinosaur was in the egg by counting the number of growth lines on the teeth.
