FO600c
This is a very nice, good quality Schafite or Ammonite in matrix. It measures
3 1/8" x 2 1/2" in a fossilized matrix measuring
6 1/2" x almost 4 7/8" x 2 3/4". The Schafite has a
natural, iridescent, pearl-like finish. This excellent fossil is
from the Upper Cretaceous Fox Hills Formation in north central South
Dakota. Close observation will reveal many other partial to
semi-complete fossils throughout the limestone matrix. These fossils
make great gifts or work wonderful as an educational tool for school,
scouts or clubs.

Here is something different from the Rock Shed's gift department; this
is a very nice and very unique fossilized Ammonite from Madagascar.
The exterior has been ground smooth, polished to show the suture lines,
and the interior shaped into a functional bowl. The Ammonite has
pretty brown and tan exterior colors with the highly detailed tan suture
lines. The inside of the Ammonite shows the dark yellow calcite in the
different chambers.
The specimen measures
almost 5 5/8" x 4 5/8" x 1 1/4" thick and weighs almost 1 1/8 pounds.
A true work of nature and man.

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.

FO603b This is a
unique smaller portion of a Dinosaur Bone from Utah. The actual
species of Dinosaur is unknown. This Dinosaur Bone specimen measures
3 3/8" x nearly 3 1/8" x almost 5/8" thick. This interesting fossil has
great detail of the bone structure throughout. We cut and polished a
portion of it to show in cell structure inside. A must have for the
fossil collector or an excellent gift for someone!

This is a very nice fossil Trilobite from Morocco. It measures nearly
2 1/2"
long x almost 1 3/4" wide setting in a matrix measuring 5 7/8" x
4 1/4" x nearly 1 5/8" thick including the Trilobite. The
uncommon Trilobite species appears to be Order Corynexochida and family
Thysanopeltidae and is from Devonian period from the Sahara Desert in
the northern part of Africa. This awesome fossil shows evidence of being
professionally repaired but displays very nice! Another photo

Another photo Trilobites are
hard-shelled, segmented members of Arthropoda and the class Trilobita that
existed throughout almost all of the Paleozoic era, flourishing in the
earlier part of it and slowly declining in the later part. The most common
trilobites were about 2-7 cm (1-3.5 in) in length, but over their long
history they ranged in size from 1 mm-72 cm (.04 in-28 in) and exhibited
so much variation that they are classified into nine (or possibly ten)
orders with more than 15,000 species. The smallest species are presumed to
have been part of the free floating plankton, while the more common,
mid-sized species probably walked along the sea floor filtering mud to
obtain food, and the larger varieties may have been swimming predators.

Here is a very cool fossilized Nautiloid from Madagascar. This particularly
large fossil
measures nearly 5" x 3 7/8" x almost 3 1/4" and has been
nicely polished on all sides.
The fossil is complete and has good detail and great color. Close
inspection shows specks of Pyrite on one side near the center and along
the chamber lines. A great educational
tool or very cool keepsake. Very cool!

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.

FO607c This is a
fossilized Shark Tooth in matrix from Morocco. The specie name is
Otodus Obliquus
and is from the Eocene period. This nice Shark Tooth with a prominent side cusp measures
2 1/2" diagonally x 1 1/4" wide in a Limestone matrix that is
4 3/8" x over 3 7/8" x nearly 1 1/4" thick. Very cool!

Sand Shark or Otodus
obliquus – (the Great Grandfather of the Megalodon) is one of the earliest
mackerel sharks. These teeth are noted for their wide triangular crown and
large side cusps (occasionally multiple side cusps). The Otodus obliquus
was the king of the early Eocene, approximately 50-55 million years ago.
These large teeth are very showy, making them a must have for every fossil
shark teeth collection. Large Otodus obliquus teeth are not easily located
in the phosphate pits in Atlas Mountains of Morocco, but can still be
affordable.

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 Tertiary 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 tooth is from the largest shark ever known to live.
The Carcharocles Megalodon sometimes ranged in size up to 60' in
length and weighed over 52 tons. This huge monster is the
largest predatory fish that ever lived, second only in size to the
sperm whale. Fossil teeth have been found that exceed 7 inches
in length. These sharks lived in the Miocene period some 23
million years ago to the Mid Pliocene times, 3.6 million years ago.
This specimen is from South Carolina.
