Dave Bowen Posted August 7, 2009 Share Posted August 7, 2009 If I'm not mistaken, the Chicxulub event was caused by an asteroid, not a comet. I guess if they claim that comets weren't responsible for any mass extinction events, they would be essentially correct... lol. Dave Bowen Collin County, Texas.

fig rocks Posted August 7, 2009 Share Posted August 7, 2009 Just goes to show we can't be too set in our beliefs and we have to be open to new evidence when it's discovered! Our knowledge keeps increasing. Link to comment Share on other sites More sharing options...

Guest solius symbiosus Posted August 8, 2009 Share Posted August 8, 2009 ^^There is debate as to whether the Chicxilub event led to the extinction at the end of the Cretaceous. Link to comment Share on other sites More sharing options...
Auspex Posted August 8, 2009 Share Posted August 8, 2009 ^^ Safe to assume that it was a tricky day for the critters living at the point of impact, anyway. As for actual global extinctions, both sides of the debate have valid points. Actual evidence is hard to come by, and subject to assumptive interpretation.

Guest solius symbiosus Posted August 8, 2009 Share Posted August 8, 2009 It is the actual lack of any corroberating data that has doomed this hypothesis to failure. It was fun while it lasted. Well, not really, it seduced a lot of, otherwise, intelligent people. http://findarticles.com/p/articles/mi_hb31...ag=content;col1 http://geology.com/news/2009/asteroid-didn...xtinction.shtml Link to comment Share on other sites More sharing options...
NSRaddict_1 Posted August 8, 2009 Share Posted August 8, 2009 A Asteroid struck the Earth at such a precise angle and location it started a chain reaction of volcanic eruptions thus blanketing the Earth in a vale of smoke and ash triggering a catastrophic event , so indirectly a Asteroid caused the demise of the Dinosaur . That and our ancestors from planet GtbK saw that in order to inhabit the new planet the large creatures would need to go ! Hey , it could happen ! Hunting fossils is fun , but discovering is better !
