English: FIGURE 7. Radiodont distribution. (A) Stratigraphic distribution during the Cambrian and Lower Orodovician. Each symbol indicates one genus belonging to one the four Radiodonta families and those of uncertain affinity, with paleogeographic terranes represented in vertical columns. For example, in Series 2 Stage 3 of South China, described radiodonts include three Anomalocarididae genera, four Amplectobeluidae genera, two Hurdiidae genera, one Tamisiocarididae genus and four genera of uncertain family affiliation. Total number of genera found in each geological time period (for all paleogeographic regions combined) indicated in the line graph on the right. (B) Paleogeographic distribution of Lagerstätten that have yielded radiodonts.
