Why would you not find trachodon with wooley mammoth fossils?
Trachodon and woolly mammoths lived in different time periods. Trachodon, a type of dinosaur, lived during the Late Cretaceous period around 70 million years ago, while woolly mammoths lived during the Pleistocene epoch around 2 million years ago. Their existence did not overlap, so their fossils would not be found together.
