*By G1N4* Well, for starters the first vertabrates were created called the jawless fish (very creative...*HINT THE SARCASM*) and other organisms, which i am not sure are vertages or not, were cepholopds, bronchiopod, ect. also this was the second period in the Paleozoic era. I just learned about this stuff today so id ont know much. so sorry if it is not enough.
What else can I help you with?
What were the major geologic events of devonian period?
there was plate tectonic movement
Which is not a major period of the geologic time scale?
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
What were the major geologic events of the mississippian time period?
During the Mississippian Period, major geologic events included the widespread deposition of carbonate rocks forming thick limestone layers, the development of large coral reefs, and the formation of coal deposits from plant materials in swampy environments. Additionally, tectonic activity led to the uplift of mountain ranges and the creation of rift basins.
What marks the end of a geologic period?
Each era on the scale is separated from the next by a major event or change. Different spans of time on the time scale are usually delimited by major geological or paleontological events, such as mass extinctions.
What period represents the last 2 million years of geologic time?
The last 2 million years of geologic time is part of the Quaternary Period, which is characterized by major advances and retreats of continental ice sheets, as well as the evolution and dispersal of humans.
What were the major geologic events of devonian period?
there was plate tectonic movement
What were the major geologic events in Jurassic time period?
The existence and extinction of the dinosaurs.
What were major geological events of the quaternary period?
Some of the major geologic events include ice ages, the formation of the great lakes, and the continents moving to where they are now.
What major geological events happened in the Ordovician period?
there was plate tectonic movement
What are the major geologic events in the Permian period?
During the Permian period, major geologic events included the assembly of the supercontinent Pangaea, significant climatic changes leading to glaciation and warming events, and massive volcanic activity resulting in the formation of the Siberian Traps. These events had significant impacts on biodiversity and led to the largest extinction event in Earth's history, known as the Permian-Triassic mass extinction.

What were the major geologic events of the Quantenary period?
Mainly the ice age. I have a project in which I have to make a PowerPoint presentation for one of the times and i chose quantenary and we are in the quantenary period right now

What was the major geologic event during the Jurassic period?
your mama was born
What are the major geologic events in the triassic period?
Not much happened really except i think it was climate change and small dinos running around, the size of a chicken. (No im not kidding)
What evidence do scientist use to place events on the geologic time scale?
they use major fossil records
