Ammonite From The Upper Triassic Luning Formation, Nevada

I imaged this ammonite (such a Triassic form is also called an ammonoid) from a public domain document; photographs from such a public domain source can be used without prior approval.

Scientifically, the ammonite is called Guembelites philostrati, from the Upper Triassic Luning Formation, Union Canyon, Nevada.
