Beecher's Trilobite Bed is a Konservat-Lagerstätte of Late Ordovician (Caradoc) age located within the Frankfort Shale in Cleveland's Glen, Oneida County, New York, USA. [1] [2] Only 3–4 centimeters thick, Beecher's Trilobite Bed has yielded numerous exceptionally preserved trilobites with the ventral anatomy and soft tissue intact, the soft tissue preserved by pyrite replacement.
A fossil specimen of the trilobite Triarthrus eatoni from the Beechers Beds, showing the sites characteristic pyritic preservation style. Located within Oneida County, New York, and the larger Frankfort Shale, the Beechers Trilobite Bed is a Konservat-Lagerstätten fossil site that dates to the Katian stage of the upper Ordovician. [1]
A Triarthrus eatoni with preserved appendages. From upper New York, United States. The preservational regime of Beecher's Trilobite Bed (Upper Ordovician) and other similar localities [1] involves the replacement of soft tissues with pyrite, producing a three-dimensional fossil replicating the anatomy of the original organism. [2]
The specimens of T. eatoni that are found in the Beecher's Trilobite Bed, Rome, New York area are exquisitely preserved showing soft body parts in iron pyrite. Pyrite preservation has given scientists a rare opportunity to examine the gills, walking legs, antennae, digestive systems, and eggs of trilobites, which are rarely preserved.
Beecher's Trilobite Bed. 460? Ma New York, US Noted exceptionally preserved trilobites with soft tissue preserved by pyrite replacement. Pyritisation allows the use of X-rays to study fine detail of preserved soft body parts. A pair of Triarthrus trilobites with pyritized soft-tissue: Harding Sandstone [40]? Colorado, US
