Anyway what I am trying to figure out is something I have been thinking about for many years. The dinosaurs didn’t die from a big explosion or anything just that the earths gravity increased and made them less competitive to smaller creatures. I have heard bone mass decreases for astronauts so I am think it must increase if gravity increased. Also I am not looking for a number but an understanding of what a creature would weigh with the increase of matter that has been hitting the earth over time. The 37,000# number is what I found on the internet as a theory to what is being added to the earth ever year so over 60 million years there must by an increaseHope someone can help
