Welcome to
Medfield(…a seemingly peaceful town)
…but a crime’s been committed!!
REMEMBER…In the Early Paleozoic Era, North
America was…
…covered by oceans!!
Throughout the Paleozoic, North America is pushed up and out of the oceans and the
continents merge to form the super-continent…
PANGAEA!!
The supercontinent begins to break apart and head to our modern-day continental
positions in the Age of Reptiles…
…the Mesozoic Era!!
So, in the Cenozoic Era, we can expect that the continent of North America,
which used to be the ocean floor, would be mostly…
…Sedimentary Rock!!!
