FO702c
This is a set of three Black Ammonites from Peru. These black
ammonites are species Lyelliceras lyelli. They are from Huaruco,
Peru, and lived in the Cretaceous Period (middle Albian), approx. 105
million years ago. They measure smallest to largest specimen - 1 3/8", 1
3/4" and 1 7/8".
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 new and different item at the Rock Shed, a Orthoceras Fossil Plate from Morocco. This
plate measures nearly 12" in diameter and has a nice polish.
The plate is hand carved so it is slightly irregular in shape. The plate
is a soft Brown color and has a nice Orthoceras fossil in one area with
other fossils scattered throughout. A nice item for any 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 something different for the fossil collector. This is a very
nice set of 3 Orthoceras Fossil Free Forms with several nice polished specimens.
The specimens measure approximately 6 1/4" to 7" in length and 1 1/2" to
1 3/4"
in width. The fossils have a smooth, polished finish and have not been
chipped out of the matrix like the Orthoceras plaques we sell. These
fossils are from Morocco. They make great decorator pieces as well as
collectible for the fossil collection.
Note: The
fossils we send will be similar to the picture since the ones we have in
stock are all very near the same size and each looks very similar to the
picture (all have good detail and are nice). You will receive three (3)
fossils.

FO706b This is a
very nice Fossil Fish Knightia from the Eocene Age from the Green River
Formation, Lincoln County, Wyoming. This fossil fish specimen is in
limestone matrix
measuring nearly 5 1/2" x 4"x
3/4". The fossil itself measures 4" 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. |
