- Panama Plate (Wikipedia)
The Panama Plate is a small tectonic plate (microplate) that exists between two actively spreading ridges and moves relatively independently of its surrounding plates. The Panama Plate is located between the Cocos Plate and the Nazca Plate to the south and the Caribbean Plate to the north. Most of its borders are convergent boundaries, including a subduction zone to the west. It consists, for the most part, of the countries of Costa Rica and Panama.
- Permian (Wikipedia)
The Permian (/ˈpɜːrmi.ən/ PUR-mee-ən) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia.
