Carboniferous explosion

The Cambrian explosion and the Carboniferous period followed the same pattern of making and breaking, but a different type of biological expansion appears in each. In the Carboniferous, organisms grew big, while in the Cambrian, they grew different shapes. The Carboniferous explosion was more quantitative, the Cambrian more qualitative. 1 think this was because the Cambrian explosion had an additional chemical boost that promoted biological invention an increase in dissolved calcium. 

Butterfield may be right to be skeptical about the Carboniferous explosion,. .. N. J. Butterfield. Was the Devonian radiation of large predatory fish a consequence of rising atmospheric oxygen concentration 2011. Proc Natl Acad Sci. 108(9), p. E28. DOI 10.1073/pnas.l018072108. 

Ammonium nitrate is the principal base material in slurry explosives and lower-cost blasting agents. It can be converted to an effective blasting agent by proper mixing with a carboniferous material such as fuel oil. Ammonium Nitrate/Fuel Oil (ANFO) mixtures are used extensively in open-pit mining and outdoor construction work because of ease of handling, availability, low cost, and safety. 

Plants ability to evolve and build new structures with oxygen almost drove the planet out of chemical balance 200 million years after the Cambrian explosion. This later period of time is the Carboniferous period. It is as distinct in the fossil record as the Cambrian, and it coincided with a rise in oxygen levels. 

Instead of an explosion of shelled forms as in the Cambrian, Carboniferous rocks contain an explosion of plants and fish, and an increase in size of all sorts of life. Carboniferous forests and wetlands resounded with the sounds of huge insects and amphibians, like dragonflies with two-foot wingspans. Even the microbes were big in the Carboniferous.
