GAL400c  MOSASAUR FOSSIL PLAQUE

This is a very nice Mosasaur fossil jaw section with five teeth from Morocco.  This genuine fossil is natural as found and is from the Cretaceous period, some 75 million years ago.  The largest tooth is nearly 3" long x almost 1 3/8" wide.  These Mosasaur teeth, jaw sections and various other fossil bone fragments rest in a sandstone matrix backed up by plaster that measures approximately 17" tall x 16" wide x over 5 1/4" thick and weighs 32 1/2 pounds.

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.

GAL401b  TRILOBITE FOSSIL PLAQUE

This outstanding Trilobite plaque is an extremely well preserved specimen from Morocco.  It has four different size, very detailed Trilobite specimens, all appearing to be Cambropallas Telesto from the order Redlichiida and Family Holmiidae.  They range in size from 4 3/4" to 8 1/2" long.  The largest Trilobite on the upper left measures over 6 1/2" wide with the smaller one on the left being almost 7 1/4" long x nearly 5 1/8" wide.  The inverted Trilobite on the upper right is almost 6 1/2" long x 4 1/4 wide and the smallest on the lower right is 4 3/4" long x 3 1/2" wide.  The matrix measures 15 3/4" wide x 17 1/2" tall x over 1 1/4" thick and weighs almost 14 1/2 pounds.  An excellent addition to any fossil collection!

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.

Trilobites are thought to represent an early stage in the step-by-step development of life on Earth though all trilobites have been extinct for the past 200 million years. Others would assert that the trilobite line itself left no descendants, but that ancestors of the trilobites would also have given rise to species that became today's horseshoe crabs. The trilobites are considered to be the first animals to have evolved true eyes.

GAL402b   MOSASAUR FOSSIL PLAQUE  

This is a very nice large plaque of Mosasaur jaw sections with numerous teeth from Morocco.  This genuine fossil is from the Cretaceous period and is about 75 million years old. The largest tooth is almost 1 1/2" long x nearly 3/4" wide. These Mosasaur jaw sections rest in a sandstone matrix that measures approximately 23 5/8" wide x 8" x almost 4" thick and weighs almost 23 pounds.  If you look closely at the pictures, you can see this fossil in matrix was carefully placed on a plaster base to preserve it. Several of the teeth have been professionally reset in position. An extremely nice fossil to display!

GAL403b  SHARK TOOTH FOSSILS

This is a very nice group of three larger Sand Shark's Tooth Fossils in matrix from Morocco.  The specie name is Otodus Obliquus and it is from the Eocene period.  The Shark's tooth on the left measures over 2 3/4" diagonally x 2" with cusps on both sides. The center tooth measures 2 7/8"  x 1 1/2" and has side cusps on both sides as well.  Overall, the matrix is over 10" x nearly 7 1/4" x almost 2" thick and weighs nearly 6 1/4 pounds.  These shark's teeth are found in a light colored Limestone.

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.

GAL404c  OREODONT FOSSIL

This is a very nice fossil skull of a small Oreodonta from the Brule Formation in the White River Badlands of South Dakota.  This was a goat-like species of terrestrial herbivore belonging to the Oreodont family.  This very detailed fossil with many intact teeth is from the Oligocene period and is about 30 million years old.  The highly detailed skull together with the light colored limestone matrix is 4 5/8" long x almost 3" wide x 3 5/8" tall and weighs nearly 1 3/4 pounds.  An awesome fossil to display in your collection!

The Oreodonta is an extinct suborder of mammal in Order Artiodactyla, and therefore distantly related to pigs, hogs, camels, hippopotamuses, and the pig-like peccaries.  Over 50 species of Oreodonta have been described. They first appeared some 50 million years ago during the warm Eocene and were widely prevalent during the Oligocene in the grasslands, prairies or savannas of what is now the North American badlands.  Today, fossil jaws and teeth of the Oreodonta are commonly found in the White River badlands in South Dakota, Nebraska, and Wyoming.  Oreodonts are Artiodactyls, even toed ungulates, sometimes called a cross between a pig and a sheep. Note that they have both large canine front teeth, but also molars for chewing plants.  They were herding animals and grazers, eating mostly grasses.  They averaged three to four feet long.

Canidae are dog or fox-like mammals, canids are familiarly dog-like, with straight, level backs, long, slender legs, large ears and long muzzles.  All are built to run but many also use stealth and pouncing to secure birds and small mammals.  Essentially monogamous, canids are unique among carnivores in regurgitating meat to feed pups and other non-hunting family members.  The Canidae of the White River fauna show similarities to modern day raccoons and foxes, and show a great variation in size.  Cynodictis gregarious was the size of a tiny fox, Daphoenus felinus that of a coyote, and Daphoenus superbus that of a wolf.  A few such as Ischyrocyon hyaenodus were huge, approaching the size of a modern day grizzly bear.

GAL408b  STARFISH FOSSIL

This is something special for a serious fossil collector.  This is a very nice quality fossil plaque with two larger Starfish and several quite small Starfish from the Ordovician or some 450 million years ago.  The species of the starfish is Ophiura, otherwise known as Brittle Star and is from the Kataoua Formation in Morocco.  The largest highly detailed fossil measures approximately 5 1/2" x 3 1/2".  The second Starfish is 2 5/8" x 2 3/4".  The small Starfish range from just under 1/8" to almost 1/2" in diameter.  These very cool fossils all rest in a matrix that is nearly 7" x over 7 1/2" x almost 1 1/4" thick.  The fossil specimen has had some professional repair; mostly evident on the back side.  An outstanding addition to a fossil collection.
