JURASSIC CATURUS FISH FOSSIL ON ATTRACTIVE
LIMESTONE PLATE FROM SOLNHOFEN
Solnhofen Plattenkalk
Formation - Eichstatt, Germany
JURASSIC
PERIOD: 160 million years ago Famous
for producing an astonishing diversity of rare and most intricately
preserved fossils found anywhere in the world, the Jurassic lithographic
limestone deposits of southern Germany are legendary. Quarries in
the region are privately held and mostly worked by hand on a small
scale. The finest grade fossils are few and far between and much
rock must be split to locate them. The best fossils are most often
kept by the quarry owners who themselves, are often collectors.
Some quarries are operated on a large scale but these are now dug with
machinery instead of manual labor. Because of this the rock is
damaged and along with it, the rare fossils. What all this means
today is that even fewer fine grade Solnhofen fossils are found and when
they are, rarely do the best pieces make it to market.
Occasionally, an old private collection surfaces and specimens are sold
or traded. This is where the rare opportunity comes along to
acquire a specimen on a level that truly is a prize find.
Typically, the older material is often the best as it was collected when
the deposits were first being worked and quality was in greater
abundance.
From
this famous formation, we offer a SUPERB quality example of the extinct Jurassic fish, Caturus furcatus.
This is a beautiful fossil of this species and features a complete and
finely detailed fish fossil on its original limestone plate. The
plate is not only large but it is has concentric bands of stunning gold
colors in the limestone slab which makes for an additional aesthetic
feature. The color is 100% natural and the fish shows well
prepared fetaures.
Superb fossil
preservation of the body and internal skeleton of the fish is very
evident. Delicate fin and bone detail is preserved, as well.
NO RESTORATION.
Caturus
was a primitive species of fish that thrived during the Jurassic Period
but went extinct by the Lower Cretaceous Period. This was a mid-size
streamlined fish similar to modern salmon. Caturus was a fast
swimming predator and had powerful, toothy jaws. It possessed ganoid
scales but as a member of the holosteans, was a more developed fish
compared to the ganoid-scaled but cartilaginous chondrosteans. The
holosteans had a bony skeleton compared to the unossified vertebral column
of earlier chondrostean fish. Caturus is unique in that its
vertebral column is only partially ossified which is why it is usually
without much detail as it was more compressible during the burial and
subsequent fossilization process.
The scales
of holosteans are a blend of a rhomboid and cycloid profile. Caturus
had scales that are more to cycloid in nature. Another feature of
the holosteans is the presence of a fully functional swim bladder enabling
neutral buoyancy compared to the earlier chondrosteans where fin movement
was required to maintain a stationary position despite the presence of a
swim bladder, albeit a smaller, barely functional one.
Some of
the largest dinosaurs that ever walked the earth were in existence when Caturus swam in the ancient seas alongside massive plesiosaurs and
ichthyosaurs!
