  1. I have come to the same conclusion as you have, through the following reasoning: Any increase of the Earth's gravity implies an increase of the Earths mass. So I concur that it is plausible that a meteorite impact could add so much material to the Earth total mass as to increase the Earth's gravity. . Also, subsequent animal species that evolved after the dinosaurs never were able to develop nearly as much body mass as the great lizards, and that certainly implies that large animals, weighing more than 3 tons, could no longer be sustained by the Earth's environment,. It has also been rather difficult for modern paleontology to make a credible model of dinosaur speed and motion, It was believed that dinosaurs were slow moving animals, judging from their bone-mass, but more recently the opposite view has been accepted, The debate whether dinosaurs where cold blooded like reptiles or warm blooded like birds further implies that much is still to be known about dinosaur metabolism. It would be interesting to address these issues taking into account a lower Earth gravity. How would it affect the current models of dinosaur movement?
