MASSIVE VERY RARE
PERISPHINCTID AMMONITE -
Agadir, Morocco
MID CRETACEOUS
PERIOD: 112 - 99.6 million years ago
This is a
rare species of the Perisphinctid species of Cretaceous ammonites from the coastal
village of Agadir, Morocco. Rarely do ammonites occur this large at the site. Most large
Moroccan ammonites of these proportions you will find in the market will
be completely carved replicas. The proof of this wonderful
specimen's authenticity is the clear evidence of untouched,
natural chamber and structural body detail on the reverse side as seen
above in the fifth and sixth images! This species is an
uncommon type compared to the more prevalent Procheloniceras which is
thicker and with a more robust chamber pattern. Viewed
from the edge, it is much more laterally compressed and streamlined, most likely
it was able to swim faster through the ocean since the drag of a thicker
shell was reduced. Another characteristic that sets it apart from
the usually encountered varieties is the individual ridges that make up
each chamber are finer and more delicate. Same shell detail is
also evident on the reverse testifying to its authenticity and rarer
variety as indicated.
Genuine
massive specimens like this example are exceedingly
rare and usually when they reach this size, they are very
"blob-like" and lack nice form and symmetry. Specimens of this quality
and size are very hard to find in genuine form as nearly all large rough
Moroccan ammonites are carved fakes made from the same limestone as the
genuine specimens are formed from. When in doubt, carefully
examine the reverse side. The ridges of the chambers should be
evident in faint form on the reverse at the boundary where the matrix
removal was stopped. Faint chamber detail is clearly evident in
the giant specimen seen in the photos above on the reverse. With
the majority of very large specimens of this ammonite being nothing more
than hand-carved replicas, it is imperative to know your source
and see this kind of detail on the reverse side of what you
purchase. In most cases, the fakes will also be substantially
lower in cost as they can be purchased for much less than a genuine
specimen goes for at the source. This superb grade ammonite is solid stone featuring the
fascinating ridged surface ON
BOTH SIDES of this ancient creature's shell.
We highly
recommend this magnificent giant fossil. It is an uncommon type
regardless of size but as the largest of this type we have ever offered,
it is very highly recommended for the advanced collector. The
pictures with the hands indicate the real magnitude of this enormous
specimen.
AMMONOIDS
evolved from nautiloids in the early Devonian period, about 400 million
years ago. They were abundant in world seas for the next 370 million
years. They suddenly vanished at the end of the Cretaceous period. These
extinct marine animals, which thrived in the Paleozoic and Mesozoic
Eras, some 400 to 65 million years ago, were cephalopods, and are thus
related to squid, octopus, cuttlefish, and the chambered nautilus.
Ammonites were able to swim, thanks to the unique construction of their
shell, which was divided into a series of air chambers. The air in the
chambers provided buoyancy for the animal to float; like modern
cephalopods, they probably moved through the water using jet propulsion.
Because ammonites lived exclusively in marine environments, their
presence also indicates the location of prehistoric seas.
The animal that lived
in this fossil shell looked something like a squid or an octopus, with
tentacles for grasping its food and moving around the ocean floor.
Some
ammonite species have been found up to 6 feet across in size, while
others never got bigger than a dime.
With its three-dimensional form and texture,
this ammonite specimen will bring any event to a halt when displayed.
It is in a class all its own, not only
desired by collectors, but treasured by interior designers and
architects alike for incorporating into a stunning display. Natural color and
wonderfully detailed. An exquisite specimen for such a rare size
and an absolute "show-stopper"!
