    Did Insects Kill the Dinosaurs?
    Question regarding the following article on CNN.com

    Did Insects Kill the Dinosaurs? Dated Thursday, Jan. 10, 2008 By MICHAEL D. LEMONICK
    Did Insects Kill the Dinosaurs? - TIME

    I was curious about the Turonian period when there seems to be a contradiction in planetary environment where the oceans where hot but there is evidence of arctic glaciers.

    Could this be due to the earth being more egg shaped at the time due to the moon's gravitational influence? (it was closer to the earth then) or some other affect on the earths circumference?

    If indeed this is the case then the outer crust of the earth would be much thinner at the equators and thicker at the Polar Regions. The thinner outer regions would be more prone to crustal movement and mantel influence creating the massive volcanism but the Polar Regions would be more stable allowing the build-up of massive glaciers in Antarctica?

    Does this make any sense?

    Thanks!

    No at least it does not make sense to me .
    Death of dinos must have taken place due to environmental changes and due to lack of food, as reported and written in the literature available, but after there death ,they must have been eaten by those ants and insects as the article says.


    Latest research are reporting manythings... I just wonder ,if the laws of physics and chemistry ramain the same... ever

    Absent evidence to suggest specific changes in the laws of physics and chemistry, it's reasonable to assume they do not change. So far that assumption has turned out to be right and assuming that physical laws stay the same has allowed scientists to make accurate predictions over and over. No reason to doubt it...

    Wow! What an interesting article! It's amazing to me that you can infer the presence of glaciers by looking at the chemical balance of oxygen isotopes in foraminferans' shells.

    But this question should have been posted in geophysics. I realized no one has been here in months, however.
