Figure 1. Dinosaur generic richness through Mesozoic by epoch. Each epoch has two metrics: left tabulation is absolute generic richness and consists of summation of different genera found during that time interval; right tabulation in each epoch is total sample counts, tallied from different geographic localities represented in that time interval. E.-Early; M.-Middle; L.-Late.TABLE 1. DINOSAUR GENERIC RICHNESS THROUGH THE MESOZOIC BY CONTINENT Epoch
