| Graptolite Classification - Class Pterobranchea |
| proposed by Kenneth E.Kinman (1994) |
| Dendroida (Middle Cambrian - Upper Carboniferous; 4 families) |
| Graptoloida (Lower Ordovician - Lower Devonian; 16 families) |
| Dithecoida (Middle Cambrian - Lower Devonian; 4 families) |
| Archaeodendrida (Middle Cambrian; 1 family) |
| Acanthastida (Lower Ordovician; 1 family) |
| Tuboida (Upper Cambrian - Upper Silurian; 2 families) |
| Camaroida (Upper Cambrian - Lower Ordovician; 2 families) |
| Crustoida (Lower Ordovician - Upper Silurian; 3 families) |
| Stolonoida (Lower Ordovician; 1 family) |
| Rhabdopleurida (Middle Cambrian? - Recent; 4 families) |
| Graptovermida (Lower Ordovician; 1 family) |
| Cephalodiscida (Lower Ordovician - Recent; 2 families) |
| Kenneth E. Kinman (1994) was of the opinion that classifying pterobranchs and graptolites in separate Classes was unnatural. He treated both groups as members of a single Class Pterobranchea and emended the name with his standarized suffix for Classes (-ea). This author also emended the endings of graptolite and pterobranch Orders from -oidea to -ida. He was only able to divide Orders into four preliminary clades, placing Graptovermida with the two living Orders in the fourth (most derived) clade. |
