Details:

Fossil Gomphoceras specimen cephalopod raised on cut base. The whole internal fossil form having individual chambers now filled with white calcite mineral formed over millions of years, is thought to be a member of the nautiloidea class of cephalopods. A fine example of the internal structure showing the chambers which have been replaced by quartz and calcite minerals over 420,000,000 to 355,000,000 years. The fossil excavated from the fossil site, cut out of solid rock, semi matt polish finishes an organic look. Read more below...

Details

Fossil of the internal nautilus cephalopod. A highly decorative Internal Gomphoceras mineralised shell and last largest living chamber. The living chamber where the nautilus would resides and being the largest chamber. The extinct marine cephalopods soft body, its head and numerous tentacles would have reached out of the largest last chamber and possibly the aperture had cover which would have been made of calcite, a hinged lid over the opening, referred here to as the mouth aperture, if the nautilus felt in danger the aperture would close.


The cephalopod added chambers as it grew, each progressively larger than the preceding one. The largest chamber cavity is easily viewed as the wide end of the fossilised shell in our illustrations, now the foot end cut for display, which is most apt, as the name cephalopod derived from the Greek, pod being foot and (keyhole head extrapolate to cephalo) cephalopod. Gomphoceras is thought to be part of the nautiloidea subclass of cephalopods as described by sowerby in 1839.


Interestingly sightings of the modern extant Nautilus Pompilius have been made off the Great Barrier Reef at depths between 200 to 400 meters, showing the pressures these Cephalopods can attain. Nautiloids are cephalopods and and wishing the cephalopod group nautiloids are The Ammonites extinction is dated around 65 million years. Ammonites are important index fossils, it is often possible to link the sediment layer in which they are found to specific geological time periods. The largest ammonite to date is around 2.5 meters in diameter from Germany.


Phylum: Mollusca, Class: Cephalopoda, Subclass: Nautiloidea, Order: Oncocerida, Family: undetermined, Genus: Gomphoceras described by Sowerby 1839.
