upper paleozoic Flashcards
-assembly of pangea
-development of chordates
-development of land plants
late paleozoic
late paleozoic life is marked by what two extinctions
-end of mississippian
-end of permian
in the mississippian, North America was characterized by
extensive limestones
when did gymnosperms come to dominate terrestrial environments?
permian
in the pennsylvanian, laurentia was a time of
extensive coal deposition
massive CO2 drop may have removed some greenhouse warming, resulting in
mid carboniferous ice age
walther’s law states
units that replace each other laterally also replace each other vertically (assuming no time breaks)
different rocks deposited in different environments at the same time
facies
-pangea complete
-end of paleozoic
-alleghany orogeny ends
permian
