Anisograptidae

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.

Anisograptids can be quadriradiate (Rhabdinopora, Staurograptus), triradiate (Anisograptus, Triograptus), or biradiate (Adelograptus, Kiaerograptus).
