We are in the Cenozoic Era which began after the extinction of the dinosaurs and many other life forms.

The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic Era.
Mammals became the dominant land animals in the early Paleocene period of the Cenozoic era, after the extinction of the non-avian dinosaurs at the end of the Cretaceous period of the Mesozoic era.

The current era is Cenozoic era. The preceding era was Mesozoic era. However if you are looking for periods in Cenozoic era, the current one is Neogene period, the preceding period was paleogene period.
If you are thinking of the dinosaur killer that struck 65 million years ago, the location of the impact was the Yucatan peninsula (in what is presently Mexico).
the extinction of dinosaurs created an opportunity for mammals. Another thing that created an opportunity for mammals in the Cenozoic Era was the fact that they evolved so quickly because they had no limiting factors.
