Tying together dinosaurs and the time for stone to form, ie fossilisation – I heard a while back that some bods (maybe in a US university?) doing tests found unfossilised tissue inside certain dinosaur bones, totally throwing off the standard 63,000,000 years ago thing.
A comet hitting a smaller oceanless earth, breaking the crust into fragments, and burying itself in the mantle could provide a mechanism for an expanding earth. What happens when ice meets lava?
