It is the proposal of this article that the development of the ability to build a layer of phosphorus rich earth over plants by termites in order to smother them and thus harvest the fungi that grow there, caused the decline in size, bone, armor, and teeth of savanna vertebrates. This happened because of the nature of the sheet erosion that took place. Also resulting was deposition of ocean phosphorites, anoxic bottom water, large ocean reptiles, and Ammonite decline. Therefore paleontologists should analyze the soil profiles associated with fossils for phosphorus in order to get as full a picture as possible.
