One of the rarer trilobites from the classic Lake Simcoe quarries. Synonymous with Ceraurus bispinosus. Evolutionary Patterns of Trilobites Across the End Ordovician Mass Extinction by Curtis R.

One of the rarer trilobites from the classic Lake Simcoe quarries of Ontario. This specimen was found in the same shale layer in which I found a large marrellomorph - soon to be published in the Journal of Paleontology. Reference: "SYSTEMATICS AND PALEOECOLOGY OF UPPER ORDOVICIANT RILOBITES FROM THE SELKIRK MEMBER OF THE RED RIVER FORMATION, SOUTHERN MANITOBA" (Westrop & Ludvigsen, 1983)

Absolutely stunning coloration. Originally described as Retiocrinus fimbriatus by Billings (1866?) Reference: Ausich, W.I., and Copper, P., 2010, The Crinoidea of Anticosti Island, Québec (Late Ordovician to Early Silurian): Palaeontographica Canadiana, v. 29, 157 p"

This species is similar to one described by Chatterton (2004) and Billings (1866) from Anticosti, Quebec, but the large geographical separation (1200kms) makes it uncertain that they are the same. Reference: Early Silurian trilobites of Anticosti Island, Québec, Canada. B. D. E. Chatterton and R. Ludvigsen. 2004. Palaeontographica Canadiana No. 22. 264 p., including 85 pls. (p. 91–261).
