FO200b  This is a fossilized Mangrove Lobster from Gunn Point, Darwin, Northern Territory, Australia.  The fossil was formed after the area was catastrophically buried by an intense cyclone, with Mangrove trees in Calcium rich mud.  The original exoskeleton of the lobster was replaced by calcium carbonate, magnesium, strontium and iron creating the fossil.  This particular specimen, although not complete, is well preserved and measures nearly 3 1/2" x 2" x almost 1 7/8".  It would make a great addition to any fossil collection.

      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.

$30.00 FO203b  Here is a very nice, above average quality, larger specimen of South Dakota Ammonites.  This very cool specimen has a nice size Ammonite with lots of other fossils including a clam visible in the matrix.  It has evidence of where other Ammonites were at some time with excellent detail.  This nice specimen is from the Fox Hill Formation in western South Dakota.  The large Ammonite appears to be a Hoploscaphites and measures almost 2 3/8" x nearly 2" in a matrix that is 3 1/4" x almost 4 1/8" x 1 7/8" and has not been polished.  A great way to begin your fossil collection.

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.

FO204c   This is a very good find! This is a Fossilized Mercenaria species Clam from Florida.   The specimen has the nearly complete large clam shell on each side with attached matrix.  The matrix is composed of calcited cemented marine fossils. Normally any calcite which is present would fluoress blue-green under shortwave and longwave ultraviolet light.  This large clam fossil specimen including the matrix measures nearly 3 3/4" x almost 3 1/4"x nearly 2".  This is a very nice representative specimen from Rucks Pit, Okeechobee County, Fort Drum, Florida. 

These specimens are from the Pleistocene age (1.8 to 5 million years old).

They make great decorator pieces as well as collectible for the fossil collection.

First and most importantly, mosasaurs are not dinosaurs.  They are extinct marine reptiles that are believed to be distantly related to monitor lizards such as the Komodo Dragon. More recent evidence, however says they were even more closely related to snakes than monitor lizards.  These large reptiles often reached lengths of 30 to 40 feet. Many complete mosasaur specimens have been found in the Niobrara Formation of Western Kansas, and some of the first mosasaur remains were collected more than 130 years ago. As a group, the fossilized remains of mosasaurs had been found all over the world, from Kansas to the Dakotas and Montana. They are also found most other states and in Canada. Overseas, mosasaurs are found in northern Europe, to Turkey, Israel to Africa, and from Brazil to Peru. And they're found in Australia and New Zealand to the islands off the coast of Antarctica.

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.

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.
