Answer to Question 1

Vast outpourings of lava in India had detrimental impacts on the climate.

Answer to Question 2

Most Mesozoic mammals had both mammalian and reptilian features. For example, while the
mammalian lower jaw has one bone, reptiles and the early mammals had multiple bones in the lower
jaw, but they also had teeth and a jaw-skull joint typical of mammals.
