Specimen PAL-11. <b>C</b>: Enlargement of a series of linear rows of oviposition scars in (B). <b>D</b>: Incised margin feeding (DT15) on an isolated pinnule of the cycadophyte <i>Bjuvia</i> sp., indicated by black arrow. Specimen PAL-1599. <b>E</b>: A leaf of the cycadophyte <i>Bjuvia</i> sp. with examples of hole feeding (DT01, DT02), indicated by arrows. Specimen PAL-294. <b>F</b>: The cycadophyte <i>Bjuvia dolomitica</i>, showing four examples of slot feeding (DT08). Specimen PAL-2147. <b>G</b>: Enlargement of slot feeding (DT08) indicated by rectangular template in (F), showing underlying matrix. <b>H</b>: Surface feeding (DT82) on both sides on the basal portion on a cycadophyte leaf of <i>Bjuvia</i> sp. Specimen PAL-729. <b>I</b>: Two miniscule galls (DT80), indicated by black arrows on the cycadophyte <i>Bjuvia</i> sp. Specimen PAL-655. <b>J</b>: Successive pinnules of the cycadophyte <i>Bjuvia</i> sp., showing several small galls (DT80). <b>K</b>: Enlargement of gall at the lower-left template in (J). <b>L</b>: The broadleaved conifer <i>Voltzia</i> sp., displaying a scale mark (DT77), circumscribed by rectangular template.
