nice, above average quality Petoskey stone specimen. The fossil
measures over 4 5/8" x 3 7/8" x 2 1/4" and is not polished. The
fossilized coral has
nice detail and a good appearance. A very nice addition to your fossil
collection.

Petoskey stones are composed of fossilized coral, Hexagonaria
percarintata, deposited in the Devonian period, some 350 million years
ago. They are found in the Gravel Point Formation of the Traverse Group in
the northwestern portion of Michigan's lower peninsula.

FO811c
This is a Shark Tooth Fossil in matrix. It is from Morocco. The
specie name is Otodus Obliquus and it is from the Eocene period. This
one measures 2 3/4" diagonally and is in matrix of over 4" x
nearly 3 1/2" x 2 1/2".
A portion of the upper tooth has been reattached to this fossil. Our
price reflects this flaw.

This is a Fossil Fish Diplomystus from the Eocene Age from the Green River
Formation, Lincoln County, Wyoming. The specimen measures 6 5/8" x 6"x
1/2" and
the fish specimen is nicely centered and measures 4 7/8" from head to tail.
This fossil fish lived some 50 million years ago. These fish are found in
a light colored Limestone.
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 natures finest art. They are highly valued
by collectors the world over.

FO814c
Here is something different for the fossil collector. This is a very
nice above average quality, colorful Ammonite. The exterior has been
ground smooth and polished to show the highly detailed suture lines. The specimen
measures over 4 3/8" x 3 1/2" x over 1" and has a nice polish. This super
Ammonite fossil is from Madagascar and displays nicely.

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

This is a fossilized Ammonite from the early Jurassic (Lias) period
nearly 200 million years ago. This is species Dactylioceras Commune
from near Whitby in North Yorkshire, England. This is a nice quality, partly
pyritized split nodule specimen with very nice detail. It measures over
3 1/4" x 3" and 1 5/8" thick.

This is a very nice find of several high quality Schafite in matrix
from South Dakota. They measure from 1" to nearly 2" in a fossilized matrix measuring
7 3/4" x 4 1/2" x 4 1/2". The Schafite has a natural, iridescent, pearl-like
finish. This specimen has a nice Nautiloid as well, at left in the
picture. 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.

Here is something different from the Rock Shed's Fossil department.
This is a very nice fossilized Caesalpinia pecorae (dvivi divi tree) leaf
resting in a matrix capsule. The fossil leaf measures 1 1/4" x
over 1/4" and the capsule matrix 2 1/2" x 1 3/4" x 5/8" and has not been polished.
A one-of-a-kind fossil for a one-of-a-kind collector.

Here is something different from the Rock Shed's Fossil department.
This is a very nice fossilized coral slab from an unknown location. We
believe it is from Utah but cannot be certain. The fossil coral slab measures
nearly 7" x
6 1/4" x 1/4" thick. The slab and many cool fossils scattered about and has been polished
on one side.

FO820c This
is a pair of Fossil Fish Knightia from the Eocene Age from the Green River
Formation, Lincoln County, Wyoming. The Limestone matrix measures
over 5" x 4 3/8" x 3/8". The fossil fish
each measure about 2 1/4" from head
to tail. These fossils lived some 50 million years ago. They are found
in a light colored Limestone. |

FO804b This
is a neat find, a complete Ammonite from Nigeria in matrix. This fossil
has not been polished or cut. The complete specimen measures nearly 3 3/4"
x 2 3/4" x 2". The Ammonite itself is 2 3/4" x 2 1/4" x
2". There are imprints of other fossils in the matrix along
with additional fossil pieces. An awesome fossil Ammonite for any collection!

Here is a great find! This is a very nice, above average quality,
fossilized Ammonite from Morocco. The specimen was carefully chiseled out of
the original matrix revealing the
detailed ridges of the Ammonite. It measures over 5 1/4"
x 4 1/2" x nearly 2 3/8", weighs over 2 1/2 pounds and has not been
polished. A super cool fossil.

FO822b This
is a large end cut of Petrified Wood from the beautiful Black Hills of South
Dakota. It measures over 5 3/4" x 5 3/4" x 2" and is polished on the
front face. This beautiful specimen has a deep shaded Brown color with
Gold, and Blackish Brown accents. It would make a great centerpiece.
This material is unique in that it is very unpredictable; some may have interesting
cavities, internal and/or external fractures and natural knots. A perfect
work of nature. Another photo
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.
