    Many theories have been put forward as to the death of the dinosaurs, some more plausible than others. I have my own theory which I am sure someone can point out the errors to if they wish, I am just a layman not a scientist.

    The Idea

    All water on Earth came from space (Earth can not produce water).
    For bacteria to create life shallow, warm waters are ideal so may have been little water then.

    Over Millenia Earth came in contact with the glacial meteor belt slowy raising the water levels and allowing the abundance of life to grow.

    Maybe 65million years ago earth was hit by glacial meteors in gigantic proportions, not one large asteriod but wave after wave of glacial meteorites.
    This could have opened up a catologue of events, (maybe one large one did hit mexico that was too large too melt on entry?)

    1. The Earths mass got larger increasing the gravity fundamentally so giant dinosaurs could not exist.

    2. The pressure of the oceans and the increased gravity start the movement of the teutonic plate causing continental drift.

    3. The increased gravity pulled Earth into a new orbital cycle away from the glacial meteor belt.

    I am sure there are many reasons why this theory is wrong but I welcome your thoughts.
    Thanks

    What about small dinosaurs?
    Mammals also grew to be very large after the dinosaurs died, one of them i think weighed 18 metric tons.

    I'm very unsure of this but I think there was an ice-age afterwards.

    Hi Fratze well 18 metric tonnes was miniscule compared to dinosaurs and maybe the earths gravity increased again during the ice age.

    Hi snowy, welcome to the forum, and telling us of your interest and ideas.
    Having said that, read and study some more. The current body of opinion
    supports the evidence of lava flood plains polluting the atmosphere way before
    the asteroid hit Yucatan area, that was the final blow to most life on earth.
    Along with a poisoned atmosphere, a sudden drop in earth temperature and no
    sunlight. But pose your idea on the forum for general discussion
    nokton.
