Did it snow when dinosaurs were around?

Answer 1

No....not until possibly at the very end during the extinction

Time:
248 to 65 million years ago

At the start of the Mesozoic, the continents were all joined together forming one large continent called Pangaea. During Mesozoic time, they pulled apart from one another. Continents move due to plate tectonics.
Climate:
·The climate most likely remained warm throughout the Mesozoic. No evidence of glaciations has been found in Mesozoic age rocks and abundant evidence of tropical species has been found in Mesozoic age fossils.
·During the last part of the Mesozoic (called the Cretaceous period) the climate warmed very much. Earth was several degrees warmer than it is today. There was much less variation in temperature between the equator and the poles at this time.
·There is strong evidence that global cooling occurred at the end of the Mesozoic. The cooling may have been caused by either a huge asteroid impact near the Yucatan Peninsula, a large amount of volcanic eruptions in the area that is today India and Pakistan, or by a combination of both the asteroid and volcanoes. The Sun would have been blocked for some time by the debris spewed into the atmosphere.
Evolutionary Events:
·Dinosaurs evolved and became abundant! Some were herbivores (eating plants) while others were carnivores (eating meat). Dinosaurs were reptiles, however there is some evidence that they may have been warm-blooded.
·Birds: During the late Mesozoic, birds evolved from a group of small carnivorous dinosaurs.
·Plants: Conifer trees evolved at the beginning of the Mesozoic. The first flowering plants evolved towards the end of the Mesozoic.
·Mammals evolved during the Mesozoic but there were relatively few species and they were small in size. During the Mesozoic, mammals were eaten by carnivorous dinosaurs.
·At the end of the Mesozoic, the Cretaceous-Tertiary Mass Extinction occurred. This was the extinction event that killed the dinosaurs (among others). Many of the animals and plants that survived the extinction event (such as mammals and birds) went on to become very abundant afterward. Likely causes of the extinction event include a large asteroid impact, erupting volcanoes, and climate change. There is evidence that all three of these happened (see climate section above).

Answer 2

The Dinosaurs were around in the Mesozoic Era, of which is divided into the Triassic, Jurassic and Cretaceous.
The Triassic was primarily dry but with large temperature variations (such as currently). This is true because in a supe rcontinent, water does not reach the middle. Since water normalizes temperature, that means the middle was very dry and very hot. The Jurassic was wetter and warmer because Pangea was breaking up, introducng the entrie continent to water. That, with the heat, increased humidity as well. Temperatures were much more constant. The Cretaceous saw virutally little difference in temperatures in the poles and equator; tmeperatures were about 10 degrees C warmer. It is still confusing to scientists as to WHY this is true; whether it was atmospheric carbon dioxide or a result of ocean currents. In the early Cretaceous though, East Gondwana did see freezing temperatures. The weird conditions, like 6 months of darkness produced nocturnal and dwarf dinosaurs.
The end of the Cretaceous saw some cooling, when the dinosaurs died out.

So in general, there is no evidence to prove snow in the Mesozoic nor are there traces of glaciation. Constructing paleoclimatic models is still very complicated and there is a large amount of conflicting data.

Answer 3

No, temperature conditions during the Mesozoic, in fact during most of the Earth's history, were several degrees higher than they are today. There is little evidence of ice, even at the poles, with major exceptions during the Permian Period (before the existance of dinosaurs) and the Edicarian, just prior to the Cambrian Period (Icehouse-greenhouse) at the end of the Proterozoic Eon. Some geologists consider current conditions to be part of Pleistocene glaciation due to polar ice.

Answer 4

It snows wherever the climate allows snow (for instance, it snowed here in SE Texas recently, even though it's normally hot and humid here). Birds are warm-blooded, and many can and do live in cold climates. With even bigger body weight ratios, larger dinosaurs, which were probably predecessors to modern birds and also warm-blooded, would have been able to retain body heat better than smaller animals. The span of time in which dinosaurs existed was extremely long, and there were probably many different cycles of ice ages that occurred during their time. During these ice ages, dinosaurs must have either migrated to warmer climates, or were already able to or evolved to cope with the cold and snow.

Answer 5

Near the poles it probably did. However mostly the dinosaurs probably didn't live there. I don't think the dinosaurs themselves would have seen much snow, unless they were warm-blooded.

Answer 6

At the poles, yes, but probably not where the dinosaurs were. The CO2 level in the atmosphere was about four times as high then as it is now, so the climate was probably warmer.

Answer 7

Yes, Actually I think it was a lot colder than we think, How could these huge animals live in a tropical climate ? wouldn't they over heat ? Dinosaurs lived for like 200 million years, I'm sure there were Ice ages during that time since they are on a 100,000 year cycle. I think Dinosaurs had feathers to keep them warm, just like their closet relatives birds ! but the feathers don't fossilize they just rot away

Answer 8

as long as the place is not near the equator..

Answer 9

Yes it did. In fact, it caused their extinction. They loved to go sledding, but they weren't good at steering, so they crashed and died.

Answer 10

In the bible it says it never rained until the flood of Noah! So the answer is no.
