Anisograptidae is an extinct family of graptolites. As the first planktic graptolites, they play a crucial role for understanding the transition of graptolites from ocean floor suspension feeders to ocean surface plankton during the early Ordovician.[1]
Anisograptids can be quadriradiate (Rhabdinopora, ), triradiate (, ), or biradiate (, ).[1]
