Displaying excellent detail throughout, from its tip, down throughout its tail, every detail of this specimen has been painstakingly revealed, giving one a very precise look and understanding of what the skeletal system of these bizarre creatures is comprised of. Not only is the ray's tail nicely preserved, but the the fine bones in its "wings" are amazingly detailed as well. This is truly a specimen anyone (collector or not) would be proud to display. One can easily mount a hanger on the back side of this specimen, allowing it to be hung on a wall. Or, it would look equally impressive on an acrylic support stand.


Stingrays are a dimorphic, carnivorous species that live much of their lives sedentary, partially buried in the shallow coastal sands of oceans and seas. Stingrays are very easily recognized due to their unique physicality, including their pointed and sometimes "barbed tip" tails.


Although Stingrays have eyes, they're thought to not have particularly keen vision, and they rely on a build in electrical sensor called ampullae of Lorenzini. These sensors allow Stingrays to sense and then hunt down their prey, similarly to the way a shark does.


Stingrays mainly rely on the motion of the seas to move themselves about. However, when necessary, they can flap their winged sides or contort their bodies, allowing them to swim swiftly to attack their prey, or escape from being attacked. Along with that, many Stingrays use their pointed tails to defend themselves. The tips of many rays can be poisoned.


Stingrays are a good example of what are referred to as "living fossils" as they still live among us and their basic anatomy has remained unchanged for millions of years.


The Green River formation in the USA covers an area over 25,000 square miles and is more than 2,000 feet in thickness. This formation, dating back more than 50 million years, is one of the largest documented accumulations of sedimentary rock in the world. At the time, the area was sub-tropical and many different species flourished.
