FOSSIL FISH # 9F01 This fossil fish stamp tool comes from the Green River Shale formation of Wyoming, Colorado, and Utah. 50 million years ago this area was covered by a large tropical fresh water lake teaming with an abundance of fish and aquatic life. This particular species of fish is Priscacara Liops ( pris ca cara li ops ) and is quite abundant in the shale formation. Density of fossils in this formation suggest that Priscacara swam in schools. The concrete stamping tool has an overall size of 18 x 9 (45.7 x 22.8 cm) with a light slate texture. PCI # 9F01 Tool Size 18 x 9
NOTHOSAUR # 9F02 This particular species of Nothosaur is known as Keichousaurus Hui ( kei chou saur us hui ) and was a marine reptile, with a long serpentine neck and tail, it lived in the warm tropical waters of the Triassic Period. Keichousaurus is a genus of marine reptiles from the pachypleurosaur family which went extinct at the Triassic-Jurassic extinction event 201 million years ago. The name derives from Kweichow in China where the first fossil of this species was discovered. The concrete stamping tool has an overall approximate size of 27 x 20 (68.5 x 50.8 cm) with a light slate texture. PCI # 9F02 Tool Size 27 x 20
PROCOLOPHON # 9F03 Procolophon ( pro co lo phon ) was a genus of lizard-like reptile, a herbivore with peg like teeth, it is quite possibly an early ancestor to all turtles and tortoises. This particular species, Procolophon Trigoniceps, was first described by Owen in1876, and survived through the Permian Triassic extinction event, 252 million years ago and thrived into the Early Triassic Period. The concrete stamping tool has an overall approximate size of 18 x 9 (45.7 x 22.85 cm) with a light to medium slate texture.. PCI # 9F03 Tool Size 18 x 9
PTERODACTYL ANTIQUUS # 9F10 The late Jurassic Period,161 to 145 million years ago, had some of the most interesting creatures ever known. This winged carnivorous dinosaur, Pterodactyls Antiquus ( ptero dact yl an tiqu us ) discovered in the Solnhofen limestone of Bavaria, Germany and was the first pterosaur species to be named and identified as a flying reptile. The concrete stamping tool replicates the fossilized bones of this creature in a positive format surrounded by a slate texture.

ARCHAEOPTERYX # 9F13 Originally discovered in a limestone quarry in Germany the Archaeopteryx (arch ae op ter yx ) is the earliest and most primitive bird known. Despite its small size, broad wings, and inferred ability to fly or glide, Archaeopteryx has more in common with small theropod dinosaurs than it does with modern birds. This dinosaur with feathers that lived during the late Jurassic Period is a clear candidate for a transitional fossil between dinosaurs and birds, this concrete stamp tool replicates the bones and feathers in a positive format. The concrete stamping tool has an overall approximate size of 45 x 34 (114.3 x 86.4 cm) with a light to medium slate texture. PCI # 9F13 Tool Size 45 x 34

At the time much of the area was covered by a large tropical fresh water lake teaming with an abundance of fish. The sediments of the Green River Formation show a continuous fossil record of approximately six million years. This particular specimen is 13 long and is a member of the species Phareodus ( phar e o dus ) the predecessor of modern day perch.

TURTLE # 9F16 Turtles are characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. The term "Turtle" may refer to the order as a whole or to fresh-water and seadwelling testudines which includes both living and extinct species. The earliest known members of this group date from the early Triassic Period, 220 million years ago, making turtles one of the oldest reptile groups. There are 356 known species of turtles alive today, with some highly endangered. The concrete stamping tool has an overall approximate size of 32 x 18 (81.3 x 45.7 cm) with a light to medium slate texture. PCI # 9F16 Tool Size 32 x 18
FOSSIL SEA FLOOR # 9F17 This concrete stamping tool creates a classic replication of the fossilized lake bottom from the Green River Formation of the Eocene era, 56 to 33.9 million years ago. The depiction here is two fossilized fish from the extinct genus Priscacara ( pris ca ca ra ) along with ammonites and clams in a slate texture. The fossil record indicates that these fish swam in schools, due to the abundance and density of their fossils. These Priscacara are related to modern day perch and are each approximately 7 long by 4. The concrete stamping tool has an overall approximate size of 30 x 18 (76.2 x 45.7 cm) with a light to medium slate texture. PCI # 9F17 Tool Size 32 x 18
SHUNOSAURUS # 9F18 The Shunosaurus ( shun o saur us ) is a genus of sauropod dinosaur from the Jurassic Period approximately 170 million years ago. First discovered and excavated in 1977 by a group of students studying paleontology in the Sichuan Province in southwest China. The Shunosaurus neck length indicates that was a low browser and the design of its jaws shows that it was well-adapted to processing large amounts of plant material. The saurapod family of dinosaurs represents some of the largest creatures to ever roam the earth, such as the Diplodocus and Apatosaurus. The concrete stamping tool has an overall approximate size of 30 x 20 (76.2 x 50.8 cm) with a light to medium slate texture. PCI # 9F18 Tool Size 30 x 20

RAPTOR NEST # 9F30 Raptor Nest with fossilized embryos of a therapod dinosaur. Theropods first appeared during the late Triassic Period 230 million years ago. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living bird species. Modern colonizing birds usually space their nests one full adult body length apart. This same trait is also apparent in fossilized nesting areas.

MACROPLATA # 9F31 Macroplata (macro plata) was an extinct aquatic basal plesiosaur of the Early Jurassic Period, 201 to 174 million years ago, which grew up to 4.5 meters (15 feet) in length. Like other plesiosaurs, Macroplata probably lived on a diet of fish, using its sharp needle-like teeth to catch prey. Its bones indicate that it was fast and powerful swimmer. Macroplata had a relatively long neck, usually twice the length of the skull, differentiating itself from pliosaurs of the time.
