Larege 1.6 Inch Prone Eldredgeops From NY

 
 
 
This is a beautiful perfectly prone Eldredgeops (Phacops) rana rana from the famous Penn-Dixie quarry in NY. These trilobites are tough to find layed out this nicely, probably 95% (at least) are enrolled or partially enrolled. It's very large for a Penn-Dixie Eldredgeops and the preparation work in fantastic. Every trilobite collection should have a nice Eldredgeops like this from New York.

The trilobite Eldredgeops gazed up at a vibrant oceanic world during the Age of Fish. These ancient arthropods are famous for the rich luster of their thick and well-preserved exoskeleton. The prominent shizochroal eye is an exquisite display of adaptation to the competitive life at the bottom of a sea exploding with diversity.

Eldredgeops have very large, separately set lenses without a common cornea. This compound eye is known as the shizochroal eye, and this style of sight is ideal for low light conditions. The unique shizochroal adaptation is characterized by up to 700 relatively large, thick lenses made of the purest calcite. A doublet system of mounted lenses within the eye reduced distortion, while perched eyes promoted a wide field of view.

Eldredgeops is a genus of the order Phacopida. They lived in the Middle Devonian faunal stage called the Givetian, which lasted from 387.7 ± 0.8 mya to 382.7 ± 1.6 mya. Phacopida means "Lens-face.” Members share a distinctive developmental stage lacking segments, called protaspis.

Shale of the Penn-Dixie, belonging to the Hamilton Group, contains shallow, tropical sea fauna of the Devonian. Along a creek in scenic western New York, Eldredgeops are often found enrolled. Prone specimens are a particularly prized treasure.

The Penn-Dixie dig site contains sediments deposited in an ancient Catskill basin of the Kaskaskian Sea. These sediments originated in the Acadian Mountains which were formed by the Acadian

Orogeny when the Avalon landmass collided with North America. Penn-Dixie is on what were the western slopes of a near-equatorial tropical basin with a spectacular array of coral reef denizens.
