<< What  she  found  was  that  the  trilobite  traces  intersected  the  worm  burrows  more  often  than  would  be expected  by  random  chance.  The  fossils  also  show  evidence  that  suggests  the  trilobites  were  selective in  hunting  their  preypreferring  smaller  wormsand  that  trilobites  attacked  their  prey  at  low  angles  more frequently  than  expectedimproving  their  chances  of  grabbing  onto  and  handling  their  prey  >>
