Leptaena dejecta
Taxonomy
Dactylogonia dejecta was named by Baarli (1995). Its type specimen is PMO 105.231, a valve (The inner mould of brachial valve), and it is a 3D body fossil. Its type locality is Skytterveien, 11 meters above base of Leangen Member, which is in an Aeronian marine mudstone/sandstone in the Solvik Formation of Norway.
It was recombined as Leptaena dejecta by Musteikis and Cocks (2004).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. G. Baarli 1995 | This is a Dactylogonia species with subparallel, anteriorly directed musde-bounding ridges in the ventral interior valve and smooth teeth braced by tiny accessory plates. The ventral valve shows sharp geniculation, while the dorsal valves are concave. The cardinalia are delicate, and the inner trans-musde septa are long, low, thin, and subparallel, bordering the median side of the anterior muscle scars. The outer trans-musde septa are very short and dose to the inner septa. |
