  Good question!
  
  There may have been more carbon dioxide produced when dinosaurs ruled the planet and that was because there was a lot more volcanic activity. Volcanoes are made when land – or tectonic plates – rub against each other, causing magma (or lava) to spew out. When dinosaurs were around, land was a huge super continent which began splitting – this opened up the Earth’s crust, causing volcanic eruptions – and the release of carbon dioxide – that lasted thousands of years.
