What was the environment like during the cretaceous time period?
During the Late Cretaceous there was a warm global climate with ice-free poles. About one-third of the earth's present land area was submerged, allowing heat from the sun to be distributed farther poleward by ocean currents and producing a climate in which cold-blooded reptiles existed worldwide. Fossil ferns and cycads found in Cretaceous arctic rock are similar to plants growing today in subtropical rain forests.
