Monograptidae

Monograptidae is an extinct family of graptolites of the Order Graptoloidea.[1] Monograptids have only one row of thecae per stipe (stem, branch), unlike the biserial graptolites which have two opposing rows of thecae per stipe.[2]

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.[2] They are known from various localities in Europe, North America, South America, China, Thailand, Australia, Algeria and Morocco.[1]
