A boundary is a borderline, a separation between two things or the edge of something.
Tertiary means third.
In this case the 'Tertiary Boundary' has a geological meaning. It is an horizon in the Earth's rock sequence that marks the end of the 'Tertiary Period' at the end of the 'Cretaceous' and the begiining of the 'Quaternary Period' - a point in time in Earth's history some 65.5 million years ago.
It is also the time when the Dinosaurs became extinct.

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.
