Paleogeography (750 Ma
Muchas personas tienden a pensar que los animales son seres inferiores al hombre debido en buena medida a cuestiones culturales, influidas por la religión, que otorgan un papel cualitativamente superior a las capacidades racionales humanas. Paleogeography is used to explain the altering positions of the continents and the traditional extent of land, mountains, shallow sea, and deep ocean basins.

Dinosaurs and palm trees lived north of the Arctic Circle and in southern Australia. The glaciers superior and receded a number of times. Though very massive, Pangaea probably did not include all of the land plenty that existed then. Ultimately, North America assimilated some South American mammals (floor sloths, armadillos, opossums, and porcupines), but the majority of South American species turned extinct.
On a global scale, collisions have diminished the dimensions of continents and expanded the size of ocean basins. Index organisms are used to find out the weather conditions, the degree of salinity, and other traits of the basin. Assuming that historical crops had local weather tolerances much like these of contemporary plants, ancient floras provide proof of climatic conditions in past time periods.
Pressure partitioning also begins to play an vital position as oblique convergence continues, accommodating deformation by the formation of parallel, strike-slip fault zones and backthrusting (southward subduction of the Caribbean plate beneath the South Caribbean deformed belt).
On the overthrusting Caribbean arc and forearc terranes, north-south rifting adjoining to the collision zone initiates and is managed by ahead momentum of southward-thrusting arc terranes combined with slab pull of the underlying and subducting, north-dipping South American slab.
