This is an authentic fossil tortoise found in the Oligocene Age Badlands of Wyoming. It is about 30 million years old. It has been painstakingly cleaned, repaired and stabilized to present a beautiful display for your home, office or collection. This is just as much a historical object as it is a work of natural art.
The tortoises of the Badlands are one of the most abundant, and are certainly among the most fascinating vertebrates from the Brule Formation. Joseph Leidy, in 1852, described Stylemys nebrascensis from several specimens collected by John Evans of the U.S. Geological Corp in an expedition to the Territory in 1849. Stylemys nebrascensis was the first fossil turtle described from North America. Specimens of these tortoises range in size from as small as 5cm to as large as a meter long.
All of the land turtles found in the Oligocene deposits of the central Western Interior are described as either Stylemys, Gopherus, or Hesperotestudos. The extant genus Gopherus has long been thought to have been derived from the Oligocene genus Stylemys, but recently paleontologists have concluded that perhaps the extant genus Gopherus existed in the Oligocene as well. Distinctions between Gopherus and Stylemys are very minor.
There are three modern descendants of these tortoises living in North America. They are Gopherus agassizii in the US Southwest and into northwestern Mexico; G. berlandieri in Texas and northeastern Mexico, and G. polyphemus in Florida. All are herbivorous and all prefer sandy soil and scrub brush. Their Oligocene ancestors probably lived a similar lifestyle.
Stylemys� enemies were few, but there have been many found overturned with their plastron broken into small pieces. Most Oligocene tortoises are missing some parts (especially limbs, and the tail region), suggesting predation.
Our cast Stylemys is made from a complete and uncrushed specimen. It has a very high dome, which is not typical for the species.
Beautifully hand painted with subtle variations in color to mimic the tones of the original fossil, this replica will make a fine addition to any serious display of fossil reptiles, or an excellent conversation piece as a unique desktop ornament or paperweight!
