Why are dinosaurs buried so deep? Did rock form over them?
In: 626
Wind and water.
Wind moves sand and dirt. Seas, rivers and lakes flood and leave behind a layer of dirt. Sometimes large fires or volcano eruptions lay down a layer of ash. That effect over 65 million years means they get buried quite deep. During that time, the loose layers of sand, dust and dirt also compress and petrify, becoming stone.
Of course, all that dirt and sand has to come from somewhere, so not every skeleton gets preserved. The ones that aren’t preserved eventually get worn down by the elements.
So, in short, not every dinosaur gets buried. But the deeper they’re buried, the better they’re preserved.
