 | | Terminology used is that of Whittington and Kelly (in Kaesler, 1997), and text-figure 1 in that volume explains the term exterior view of the cranidium or cephalon as a view which shows the maximum surface area. |
 | | The Upper Cambrian trilobites described by Rasetti (1944, 1945a, 1945b, 1963) were collected from boulders in conglomerate layers occurring in the Levis Formation at Levis, Quebec. |
