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, Staurograptus), triradiate ( Anisograptus, Triograptus), or biradiate ( Adelograptus, Kiaerograptus). [1]
