Histiodella is an extinct genus of conodonts.
Histiodella wuhaiensis is from the Ordovician of the Lower Klimoli Formation in China.[2]
Histiodella kristinae forms a conodont zone, in the Table Cove Formation, Table Point, "Middle Table Head" and Table Cove, in the Middle Ordovician of Newfoundland, Canada where the trilobite species Lonchodomas clavulus or Galbagnostus galba are also present.
