what was the name of the super continent during the mesozoic era?
pannotia
the mid-atlantic ridge started to form in the early jurassic period (175 million years ago), breaking apart the super continent pangaea and beginning the expansion of the modern atlantic ocean. it has widened steadily to its present size. this rifting event separated north america from africa, and the area known today as virginia became the trailing edge of the newly formed north american continent. the jurassic period is found in the mesozoic era, or the age of the dinosaurs. the mesozoic era spanned a length of time from 251 million years ago to 66 million years ago.

at the close of this period came the permian–triassic extinction event in which 96% of all marine species vanished and from which bio-diversity took 30 million years to recover.

during the triassic (252–201 ma), much of scotland remained in desert conditions, with higher ground in the highlands and southern uplands providing sediment to the surrounding basins via flash floods. this is the origin of sandstone outcrops near dumfries, elgin and the isle of arran. towards the close of this period sea levels began to rise and climatic conditions became less arid.
