Welcome to CoreFacts, where we're always short on time and big on science. I'm Jessica Robertson. Today's question is pretty interesting.
Where did dinosaurs live?
Paleontologists now have evidence that dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (about 230 million years ago) the continents we now know were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
Its pieces then spread across the globe into a nearly modern arrangement by a process called plate tectonics. Volcanoes, earthquakes, mountain building, and sea-floor spreading are all part of plate tectonics, and this process is still changing our modern Earth.
