21. To the west, the Gascoyne Complex is overlain unconformably by sedimentary rocks of the Phanerozoic Carnarvon Basin. 22. Modifying the CPT model to account for the entire Phanerozoic including multiple Wilson Cycles would complicate the model considerably. 23. Phanerozoic unconformity-related deposits occur in Proterozoic metasediments below an unconformity at the base of overlying Phanerozoic sandstone.24. Phanerozoic unconformity-related deposits occur in Proterozoic metasediments below an unconformity at the base of overlying Phanerozoic sandstone. 25. Over the past 600 million years, Phanerozoic time, the earth has supported a complex population of organisms. 26. Hard-shelled creatures appeared toward the end of that time span, marking the beginning of the Phanerozoic era. 27. In the early Phanerozoic , increased atmospheric carbon dioxide concentrations have been linked to driving or amplifying increased global temperatures. 28. During the Phanerozoic the biodiversity shows a steady but not monotonic increase from near zero to several thousands of genera. 29. An extensive study published in 2015 supports the presence of a trend toward larger body size in marine animals during the Phanerozoic . 30. Royer, " et al . " ( 2007 ) determined climate sensitivity within a major part of the Phanerozoic .
