(1) Perhaps the most basal system in which denticulate structures are reasonably well known is the feeding apparatus of conodonts.(2) The denticulate ligaments vary in number between 18 and 22 in normal individuals.(3) Sculpture on the inner side of the outer lip varies from absent to lirate to denticulate .(4) The outer lip is crenulated on its edge, and smooth or weakly denticulate on the inner side.(5) Both mesial and distal edges of the crowns are coarsely denticulate , with the denticles oriented at an angle of approximately 45u00b0 with respect to the long axis of the crown.(6) The outer side is smoothly rounded; on the inner side the anterior edge is faintly denticulated .(7) For example, at Smiling Dan, six blade tool categories were recognized, including denticulated , unretouched, retouched, notched, truncated, and side and end retouched.(8) Ornithoid eggshells are equally abundant and occur in association with relatively uncommon sauropod eggshell fragments and denticulated theropod teeth.(9) In some specimens the anterior edge of the base is serrated or irregularly denticulated .(10) Because of the denticulated architecture of the rim, with its numerous and perilous lookouts, this would add countless miles to our trip.
