Summary
| Description |
English: Figure 3. Two different methods for compensating for the incompleteness of the marine genus fossil record, each applied to different data sets, yield strikingly similar patterns of stage-bystage marine Phanerozoic per genus extinction rates (genus extinctions/genus/million years). The similarities include the timing and relative magnitudes of the peaks, and the timing of (some of) the stages with zero or close to zero extinction rates. Top Panel: From Foote (2007), based on his analysis of Sepkoski’s compendium (Foote, 2003). Bottom Panel: From Kocsis et al. (2019) using the Paleobiology Database. The shading guides the eye to the period boundaries. Ma = millions of years ago. |
