GENUS/SPECIES NAME:  Tharsis dubius

GEOLOGICAL AGE: Upper Jurassic
(150 million years old)

STRATIGRAPHIC FORMATION: Solnhofen Plattenkalk (limestone)

LOCATION: Eichstatt, Bavaria, Germany

DESCRIPTION:  This is a very nice example of the bony fish Tharsis dubius, a member of the Teleostei fish, exhibited within a very nice slab of the world-famous Solnhofen limestone of Eichstatt, Germany.  The first true bony fish first became apparent in the fossil record in the Triassic Period and, as they  evolved, true bony fish gradually displaced the bony ganoid fish that preceded them.  Within the Solnhofen plattenkalks, a large number of different genera of the true bony fish have been recovered and, while many of these genera are rare, the Teleostei fish are far more common than fossils of the bony ganoid fish.  The magnificent Tharsis is a relatively common fish which is possessed of large, almost almond-shaped eyes, with the body being slender to somewhat thickset, and with both an elongated head and a slightly pointed snout.  The fish fossil’s dorsal fin arises somewhat posterior to the midpoint of the body, and the caudal tail fin is divided, with narrow fin lobes.  The fine preservation as noted in this specimen derives from the anoxic environment of the vast Jurassic ocean which covered this region of Bavaria at that time as well as the finely grained limestone matrix within which this fossil was preserved, capturing exquisite detail and, at times, soft body parts and skin/feather impressions. 

This fossil is centered and extends to the right, with the body curving upwards on approach to the right slab margin.  Bodily details are well preserved, including all fins, the tail and the skull.  The specimen rises from the specimen in relief and exhibits a golden-brown coloration, with dendrites arising from the tail region most prominently, but being also evident along portions of the fish body.  The large limestone slab ranges from beige to a beautiful golden-orange. The negative plate which accompanied this specimen was sadly broken, but can repaired and included at a significantly discounted price. This is a very handsome and large example of the more common bony fish Tharsis dubius, available at a quite reasonable price.
