blainvillei Paleozoic Fish Fossil from Odernheim Red Beds
Actinopterygii (ray finned fishes), Order Paleonisciformes, Family
Time: Lower Permian
Jeckenbach Formation, Rotleigendes (Red Beds), Odernheim, Germany
is a particulary well preserved example of a Paleoniscoid fish known
as Aeduella. The paleoniscoids were the first ray-finned fish, a
feature readily seen here. It is a middle sized predatory fish,
with a laterally compressed body, very large eyes, scales rectangular.
Some 40 or more families appeared during the Carboniferous and Permian
Periods. The Jeckenbach Formation is famous for the abundant fish
genus Paramblypterus found there. The Aeduella are rarely found.
They come from a thin layer within the larger formation. The matrix
is lighter in color and of a different composition than the black
shaly surrounding strata. Quarrying at the site ended in the 1980s.
