Question
-Do they have some fact that suggests as much as time hard cold/dark after event k-t, do how many sew they date on this period?  
-if they have tests that the cold/dark took place, some place exists where this test is not located?  
-i want to see some fossils of leaves of plants of the period cretácic where it could locate that?  
-It can get me or to tell me some address where I can see the dimension of those craters that produced were after event k-t  
-with regarding some animals of the I generate Pterosaurus, did they weigh several tons and the wings were not so long, I want to know if it exists in the scientists, some restlessness with regard to if alone they drifted or did they fly?  
-Do you know, the dividing line of the layer of clay of event k-t, to become of meters inches?  
-Have I heard speak of multi species of inexplicable bones of animals of that period in great magnitude, where this storages have been?

Answer
Hi Kamil,

Do you have access to the National Geographic?  There are several very good stories in this publication about the K-T event and its impact on life on Earth.  

The KT event caused a cloud of dust which hid the sun and brought about a climatic winter over much of the Earth.  There may have been some areas which were not a deeply affected but for the most part, the impact lasted decades.  It is similar to the "mini ice age" of the 1600's and 1800's caused but the eruption of Tambora and Krakatoa (volcanoes).

Fossils of plants from the Createous period are found in many places from China to the Americas.  Some of the best are found in China.

I am not familiar with the Pterosaurus.  Are you sure of its spelling?

The KT event boundry materials are in the meters thick in the Americas and upwards of a 10 centimeters in India and parts of Asia.

There are many fossil beds around the world from the KT boundry period.  Many can be found in China, North Africa, The American South West, and elsewhere.  Many of these areas are now deserts and this has helped in the preservation of these materials.

If you do not have access to National Geographic please let me know and I will look for web site links for you.
