Chalk usually refers to the white colored, soft, powdery limestone rock that is primarily comprised of fossil shells. These are basically dominated by the calcite minerals.
By the end of this period, the dinosaurs were completely wiped out from the earth and the flowering plants started to evolve after the mass extinction event, which is commonly known as the Cretaceous-Tertiary boundary (K-T boundary).
