Monograptidae

Monograptidae is an extinct family of graptolites of the order Graptoloidea. Monograptids have only one row of thecae per stipe (stem, branch), unlike the biserial graptolites which have two opposing rows of thecae per stipe.

Fossil record

Fossils of Monograptidae are found from the Ordovician to the Devonian (age range: from 460.9 to 402.5 million years ago). They are especially important during the early Silurian. They are known from various localities in Europe, North America, Argentina, China, Central Asia, Southeast Asia, Australia, Algeria and Morocco.
