Dating dinosaurs and other old things
Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.They were found together with fossils of land plants, including pollen from trees and tree ferns, as well as with fossil marine animals.The remains of dead land animals and plants were probably washed down a river and into a shallow bay, where they mixed with the remains of dead marine animals.
The sandstone containing the fossils is above a layer of late Jurassic greywacke and under a layer of late Cretaceous mudstone.The results can be as much as 150 million years different from each other! They then pick the date they like best, based upon their preconceived notion of how old their theory says the fossil should be .So they start with the assumption that dinosaurs lived millions of years ago, then manipulate the results until they agree with their conclusion. So why is it that if the date doesn't fit the theory, they change the facts?This material was compressed together with sediments into a sandstone rock.The fossils and rock tell us about what lived in prehistoric Hawke’s Bay and what the environment was like.
