Material collected in previous years (1983-1998, 2009) comes mainly from the level of the 1st oryctocoenosis.
This conglomerate layer corresponds to the 1st oryctocoenosis represented mainly by separate compactly lying bones including large and very large plates, sometimes partly articulated skeletons and aggregates of sarcopterygian scales, as well as many fragments of bones.
The 2nd oryctocoenosis is associated with that part of bed 1.
Here, at the bottom of bed 2 the fossils of the 3rd oryctocoenosis are found within an intraformational conglomerate.
Bothriolepis ornata dominates the 1st and the 3rd oryctocoenosis (35.
The 1st oryctocoenosis shows a slightly poorer sorting, 75% of all bones are 1-36 mm long, and reach the maximum length of 138 mm.
Within the 3rd oryctocoenosis 75% of all bones are 1-39 mm long, the maximum length being 154 mm.
Some articulated placoderm skeletal elements are known from the 1st and the 3rd oryctocoenosis, two specimens consisting of several scales of Holoptychius in partial articulation, as well as articulated lower jaws of Holoptychius and
Platycephalichthys, while only separate bones are present in the 2nd oryctocoenosis.
Taking all macroscopic remains into account, the articulation index in the 1st oryctocoenosis is the highest, reaching 44%, and the same index counted for the head shields of B.
ornata is better represented in the 1st and the 3rd oryctocoenosis than B.
The highest concavity ratio is characteristic of the 3rd oryctocoenosis where 83.
