MONOGAPTUS
MONOGAPTUS
Graptolites of this genus had a single stipe and a highly variable form; they could be completely straight, gently curved, or completely spiral. The form of the Thecae is vital to identification. In this genus there was a tendency for thecae to become isolated from one another. Some evolved very rapidly, so species of this genus are easily recognizable and stratigraphically useful.
Habitat: It floated in open seas.
