Double Ceraurus From Walcott-Rust Quarry

 
 
This is a double Ceraurus pleurexanthemus specimen from the famous Walcott-Rust quarry in NY. The Ceraurus layer in the quarry has been completely unproductive the past two seasons, so there are very few of these trilobites being found now. This pieces has two specimens, the larger being 1" long on a 3.3x2.6" squared off piece of limestone. They have been prepared with air abrasives under microscope and stand out with nice relief against the surface.

Walcott-Rust quarry located near Russia, NY, is one of the most historic trilobite collecting localities in the world. It was first worked by famed paleontologist Charles Doolittle Walcott along with William Rust in 1870. It was where Walcott was first introduced to trilobites; he later went on to make many amazing discoveries across North America including the famed Burgess Shale. After being lost for over a century this quarry was rediscovered by Thomas Whitely 1990's who dug and researched the site heavily. It's now leased by Trilobites of America, LLC. Not only is it producing some of the most amazing trilobites found in the US, but outstanding new contributions continue to be made to science.

The limestones of this quarry produce arguably the best preserved trilobites in the United States. Many of them perfectly 3D with no compaction at all. These include types like Ceraurus, Isotelus, Flexicalymene, Sphaerocoryphe and many more. Collecting the Walcott-Rust quarry is brutally hard. It requires extracting large blocks of solid limestone (often weighing several hundred pounds) using massive pry bars, 20 lb sledge hammers, wedges, a lot of brute force, and rock quarrying know how. These large blocks are then broken down into smaller and smaller pieces, looking for cross sections of the black trilobites in the black rock (a nearly impossible task). When a trilobite is found the real work begins, painstakingly extracting it from its limestone tomb under high powered microscope using air scribes and abrasives.
