This is something different for a fossil collector and a really great
find! Here are very nice fossilized Orthoceras stand up. The
larger fossil specimen measures over 4 5/8" x over 3/4" and the curved one is
4"
x nearly 5/8". The stand overall is over 6 1/2" tall x almost 6"
wide x
nearly 2 1/2". A
unique and great addition to any fossil collection. Orthoceras was a marine cephalopod, this particular species was straight
shelled and they thrived some 400+ million years ago in the Paleozoic era.

Here is a very nicely polished Ammonite
from Madagascar. The specimen measures almost 4 1/2" x 3 5/8" x
nearly 1" and
has a nice polish on the both sides. The larger Ammonite has a nice Yellow

Ammonites are extinct members of the cephalopod group of mollusks. Only
a limited number of species have survived to the present day which includes
the squid and the chambered nautilus. Ammonites had a multi-chambered shell,
and added more chambers as it grew, always living in the outer chamber.
They lived in the Cretaceous period some 63 to 130 million years ago.

has several very distinct Belemnite fossils throughout the matrix. A
very nice starter fossil or just add it to your collection.

Belemnites
or Belemnoids are an extinct group of marine Cephalopod which are very similar
to the modern Squid and closely related to the modern Cuttlefish. The
possess an ink sac, but unlike the Squid, they have ten arms of equal length
and no tentacles.

Here is a very unique dish craved from Orthoceras and Geisonoceras
fossils in matrix from Morocco. This platter has a very nice
Geisonoceras carved out in the center with other fossils scattered in the balance of the dish. The dish measures
8 1/2"x
6 1/2" x nearly 1 1/4" and has
a nice polish. It has a slight nick in the outer edge that is
reflected in our price. This would make a great gift or keep it for yourself!

Orthoceras is a genus of extinct Nautiloid Cephalopod. These fossils
are common and have a global distribution which occur in any marine rock,
especially Limestone. These are slender, elongated shells with the middle
of the body chamber transversely constricted and a sub-central
orthochoanitic siphuncle. The surface is ornamented by a network of fine
lirae or fine lines/ridges.

This is a very nice, high quality Schafite in matrix. This fossil
is from South Dakota. The large Schafite measures nearly 1 1/2" x 1
1/4" in a fossilized matrix measuring 4 7/8" x 3 1/2" x 2 1/4". The
Schafite has a natural, iridescent, pearl-like finish. These fossils make
great gifts or work wonderful as an educational tool for school, scouts or
clubs. Close observation
will reveal several other partial to semi-complete fossils throughout the
matrix. Another photo

This is a very nice Fossil Fish Diplomystus from the Eocene Age from the
Green River Formation, Lincoln County, Wyoming. This fossil fish specimen
is in a tan limestone matrix measuring 9 7/8" x 5 3/4"x over 3/4".
The fossil itself measures 5 7/8" from head to tail. This fossil fish
lived some 50 million years ago.
In southwest Wyoming (and parts of Colorado
and Utah) in the Green River Formation are found some of the world's most
outstanding specimens of fossil fish. The Green River system was
composed of three lakes: Lake Ulinta, Lake Gosiute and Fossil Lake.
These Eocene Lakes lay in a series of intermountain basins formed by
geological events that uplifted the Rocky Mountains during the early
Tertiery time.
The Climate was much different from the desert-like
climate of this area today. Both the fauna (crocodiles, alligators,
boa constrictors and some subtropical fish families) and the flora (such as
large palm trees) indicate a climate much like that found along the Gulf Coast
today. Large amounts of ash found in the sediments indicate that volcanoes
were particularly active at this time.
The fossils found in the Green
River Formation are between 40-60 Million years old and are in excellent preservation.
The most common fish found in the formation is the Knightia, a herring-like
fish. They are found singularly or in large groupings. These groupings
are referred to as "Mortality Layers" and are believed to have been caused
by extensive ash fall-out after volcanic eruptions. Some of the other species
of fish found in the Green River Formation are: Phareodus, a carnivorous
fish often found up to 2 feet in length and having many sharp teeth.
Mioplosus, a true perch, and Priscacara, a sunfish-like fish with stout dorsal
and anal spines. There are also turtles, stingrays, crocodiles and alligator
gar-fish.
The fossils of the Green River Formation
- each one unique - are some of nature's finest art. They are highly valued
by collectors the world over. |

This is a very nice, good quality Schafite in matrix. This fossil is
from South Dakota. It measures 1 1/2" x 1 1/4" in a fossilized matrix measuring
4" x 4 1/2" x over 2 1/2". The Schafite has a natural, iridescent, pearl-like
finish. These fossils make great gifts or work wonderful as an educational
tool for school, scouts or clubs. Close observation will reveal many
other partial to semi-complete fossils throughout the matrix.

This is an extra large, above average quality
specimen of Petrified Wood Slab from Madagascar. It has been highly
polished on one side and measures 11" x 11" x 1/2". The wood has
a nice blend of Earth tone colors and has a very different, irregular shape
and design.
Petrified Wood is a type of a fossil as it consists of fossil wood where
all the organic materials have been replaced with minerals while retaining
the original structure of the wood. These minerals are most often Silicates
such as Quartz. Other minerals, Manganese, Iron and Copper, in the water
or mud during the petrification process give Petrified Wood a variety of color
ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.
Petrified Wood can preserve the original structure of the wood in all its
detail all the way down to the microscopic level. Structures such as
tree rings and the various tissues are often observed features. Although
Petrified Wood can be found worldwide, it is rather rare in larger quantities
and at times can be difficult to obtain by the average collector.

FO601c Here is something different from the Rock Shed's
gift department. This is a very nice, above average quality
Octagon Orthoceras
Fossil box. It measures over 5 1/2" x nearly 2 5/8" tall with the lid and is polished
on the top of the lid and the outer sides. The box has a soft Black
color with well defined Orthoceras
fossil on the lid, as well as other Orthoceras
fossils in the matrix on the bottom. A true work of nature and
man.

This is a fossilized Shark Tooth. The specie name is Otodus Obliquus
and from the Eocene period. This Tooth is in a Limestone matrix and measures
2 3/4" diagonally and is from Madagascar. Close observation would reveal
minor damage to the very tip of the tooth, and though it does not take from
the appearance, we have reduced the price. |
