What is the K-t boundary layer?
K-T stands for Cretaceous-tertiary boundary. The K is used instead of a C to help that there is no confusion between the Cretaceous and Carboniferous Periods; as the Carboniferous Period was among one of the first periods. The K-T boundary is marked by the element named Iridium, the K-T boundary contains approximately 31% iridium, this element is rare on Earth, common in space debris, such as asteroids and meteors/meteorites, such as the one believed to have hit the Earth causing the extinction of the dinosaurs. The Cretaceous was the last of the dinosaur bearing periods. The Tertiary period is the period we as humans live in currently.
Were animals on Pangea?
Theoretically, Pangaea existed during the Jurassic Period. If you are familiar with the Michal Cricton novels, you are aware that during the Jurassic, the dinosaurs flourished. The Jurassic is the second element of the Mesozoic Period (Triassic, Jurassic, and Cretaceous). You should be aware that the dinosaurs are theorized to have died off at the end of the Cretaceous (look into KT Boundary Theory).
