Very 3D Isotelus Trilobite - Walcott-Rust Quarry

 
 
 
 
This very 3D trilobite literally looks like it is trying to crawl off the rock. It's perfectly inflated Isotelus gigas from the famous Walcott-Rust Quarry in New York. This species can be found other locations in New York and in Canada but the ones from this quarry are unparalleled in the level of preservation.

It's 1.9 inches long and comes from the Isotelus layer in the quarry, known for producing exceptional specimens of Isotelus. The quarry was fairly unproductive this summer, this is one of only a handful of complete Isotelus I found. The preparation on this specimen is well done, with just a tiny bit of restoration near the repaired crack on the tail.

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 back in 1870. It was where Walcott was first introduced to trilobites and he later went on to make many amazing discoveries across North America included 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. Collected 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 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 it's limestone tomb under high powered microscope using air scribes and abrasives.
