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.

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.

The Shunosaurus ( shun·o·saur·us ) is a genus of sauropod dinosaur from the Jurassic Period approximately 170 million years ago. First discovered and ex- cavated 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 ma- terial. The saurapod family of dinosaurs represents some of the largest creatures to ever roam the earth, such as the Diplodocus and Apatosaurus.

Macroplata (macro·plata) was an extinct aquatic basal ple- siosaur of the Early Jurassic Pe- riod, 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 rela- tively long neck, usually twice the length of the skull, differenti- ating itself from pliosaurs of the time.
