i dont think dinosaures lived in the age of pangea coninent.....then the land mass was still evolving....if dinosaures got extinct in pangea continent then dinosaures fossils would have drowned in oceans sea beds....and scientists say that indian subcontinent collided with eurasia forming himalayas 45 million years ago........there used to be ocean between india and china 45 million years ago and dinosaures got extinct 65 million years ago.....no chance of volcano erupted from india would have spread to the entire world across continents and killed dinosaures
