Which came first the Jurassic or Triassic period of geologic time?
The Triassic period came before the Jurassic period in geologic time. The Triassic period lasted from around 251 million to 201 million years ago, followed by the Jurassic period, which lasted from around 201 million to 145 million years ago.
In the mississippian period what did the earth surface look like then?
Buildup of carbon deposits led to surplus oxygen in the atmosphere. Oxygen built up in the Mississippian period and by the end of the carboniferous period, 35% of the atmosphere was oxygen. -nb
What came after the triassic period?
After the Triassic period, the Jurassic period followed. The Jurassic period lasted from approximately 201 to 145 million years ago and was characterized by the dominance of dinosaurs, the evolution of new species, and the breakup of the supercontinent Pangaea.

What is a description of the Paleozoic era?
The Paleozoic Era is the first and longest era in the Phanerozoic Eon, and is one of three, the two other eras being the Mesozoic and Cenozoic. Paleozoic is derived from Greek and means "ancient life." The Paleozoic lasted from roughly 542 to 251 million years ago, and is subdivided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The era began with the advent of multicellular life, and ended with the most severe mass extinction in Earth's history, destroying 96% of all marine species and 70% of terrestrial vertebrate species. The Paleozoic Era saw the development and diversification of all the modern phyla and most of the groups of life we see today, including invertebrates, arthropods, fish, amphibians, and reptiles. Most groups of marine and terrestrial plants also arose and flourished during this time. Mammals and birds would not appear until the Mesozoic Era, which came after.

The Pennsylvanian and Mississippian periods can be best explained by the carboniferous system which is divided into a number of sections. The division came from the North America stratigraphy.
What came first the Mesolithic or the Paleolithic period?
