Answer:
The Marsupials would be extinct as they wont be able to migrate to South America and Australia.

Contour lines determine the steepness of the land by how close they are together. Generally, contour lines rise to a particular scale (e.g. a line for every ten metres), therefore, if the contour lines are closer together then the height of that particular area has risen more steeply than if the contour lines are further apart where the steepness has increased more gradually.
Fossils (from the Latin fossilis, which means 'excavated') are the remains or signs of the activity of past organisms.These remains, preserved in sedimentary rocks, may have undergone changes in their composition (by diagenesis) or deformations (by dynamic metamorphism) more or less intense.
