What caused the climate during the Jurassic period?
A drop in temperatures occurred at the Jurassic-Cretaceous boundary. It has been suggested that increased volcanic and seafloor-spreading activity during the Jurassic released large amounts of carbon dioxide—a greenhouse gas—and led to higher global temperatures.
What was the weather like when the dinosaurs lived?
When dinosaurs ruled the Earth, the climate was most likely hot and humid. There is no evidence of Ice Ages or glaciations found in rocks of this age. There is a lot of evidence of tropical species existing at this time.
What caused the end of the Jurassic period?
Events marking the beginning and end of the Jurassic period This dinosaur extinction was paralleled by a shift in dominate vegetation from the conifers and cycads of the Jurassic period to shorter, primitive flowering trees (346).
Did dinosaurs live in hot climates?
Dinosaurs inhabited all latitudes, and although the climate in the age of dinosaurs 65 (million) to 150 million years ago was much warmer than today, the animals could nonetheless maintain high body temperatures in polar climates with freezing or near-freezing conditions.
Did any dinosaurs live in cold climates?
But Rich and other scientists working in Australia, Alaska and even atop a mountain in Antarctica have unearthed remains of dinosaurs that prospered in environments that were cold for at least part of the year. Polar dinosaurs, as they are known, also had to endure prolonged darkness—up to six months each winter.
What are some major events that happened in the Jurassic period?
