Description:
This is a wonderfully preserved specimen of one of the uncommon
species from the famous Solnhofen Limestone. Another unusual aspect
of this specimen is the quarry from which it was excavated. Generally,
fossils from the well-known quarries have little color, and many
are enhanced to show better. This specimen is a deep sweet chocolate
color which is totally natural, and found specifically at this quarry
site and hence results in it’s great reputation. Very few
specimens from this quarry have been available. Please also take
note of the exquisite 3D preservation of the scales and tail fin.
The upper portion of the body and head are somewhat twisted, exposing
the under-side of the head. The back-side of the plate has been
reinforced for stability.
Actinopterygians,
from primitive Coccolepididae to advanced teleosts, are represented
in the Solnhofen lithographic limestone. These are fishes with rhombic
and round scales. Ganoid scales of the lepidosteoid type are found
in caturids such as Furo. Ganoid scales are usually rhomboid in
shape and have articulating peg and socket joints between them.
They are modified cosmoid scales which consist of a bony basal layer,
a layer of dentine, and an outer layer of ganoine (an inorganic
bone salt). Actinopteri are related to sturgeon. Dating back to
the Permian period.
