The Title explains itself. What Creation Theories do you take an interest in? Why do you believe your ideas are correct? Do you have any secondary sources to back up your claims?
I, like most, take in the theory that the earth was struck by a massive comet near the Gulf of Mexico. Although, like today, the climate may have quickly changed, making it hard for most species to adapt even by means of natural selection.
Of course, there are also the ideas of massive volcanic outbreaks, disease, being out competed by mammals, etc.
Discuss.

The K-T extinction wasn't caused by a space rock forming the Chicxulub crater in Mexico's Yucatan Peninsula. It was caused by huge volcanic explosions in India that created the Deccan Traps lava beds, which covered 580,000 square miles, or more then twice the area of Texas. The impact and the vocanic explosions both would have spewed sulfur dioxide, dust and other emissions into the atmosphere, altering the earth's climate. Which would have cooled the surface of the planet and created acid rain. Professor Gerta Keller of Princeton University determined that Dinosaurs were still around 300,000 years after the Chiculub creator. She added,"There is essentially no extinction associated with the impact." The Deccan volcanism occured "Just before the K-T boundry" according to geophysicist Vincent Courtillot of the University of Paris. After the first flow,"the species disappear, we have essentially very few left,"Keller said. After the fourth flow the extinction was complete. The Chicxulub crater put 50 to 500 billion tons of sulfer in the air, but the Deccan Traps spewed on the order of 10,000 billion tons into the atmosphere. "If there had been no impact,we think there would have been a mass extinction anyway," Courtillot said. ;D

Wow, interesting.
I have never heard of that before. Can I see a link to the source of this stoneage?

Just look under Chicxulub Debate there is all kinds of stuff. There was a show about it not long ago on one of the science channels. Let me know if you find it.

I did find some info! Wow, it makes a lot of sense doesn't it?

We are just in the middle of an interglacial period. Within a few hundred years things are going to get A LOT colder too.

We are just in the middle of an interglacial period. Within a few hundred years things are going to get A LOT colder too. Data from the US National and Ice Data Center say that much of the ice in the Artic Sea is so thin that the Artic will be ice free in the summer within 5 to 10 years. Some are predicting 2011. Sea ice had a higher reflectivity then ocean water, so as the ice melts, the water absorbs more of the Sun's energy and warms up more, which in turn warms up the atmosphere more. Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century then the massive Greenland and Antartic ice sheets, according to a new University of Colorado at Boulder study. The melting of ice can set free large volumes of methane, which would in turn increase global warming. Methane is a much stronger greenhouse gas then carbon dioxide. Greenland is already losing ice to the oceans, contributing to the gradual rise in sea levels. The ice holds enough water to lift sea levels globally by about 22FT if it all melted. A sea rise of only 1 meter in Bangladesh would put half the nation underwater, displacing more then 100 million people. This will also increase weather extremes like drought, flood, hurricanes, tornados, forest fires ect. ;D

I don't think we will after know the true answer, but it is fun to have theories

You must also think about creatures that SURVIVED the extinction,take the frog for example there is a theory of acid rain ... well if it happened the frogs will be completely wiped out because of their soft skin and they will unable to find a shelter for the rain.
