Kanopus Posted September 16, 2020 Share Posted September 16, 2020 Hello from Moscow, Russia I bought this trilobite years ago on that auction site. I dont have clear info about it. Probably Eldredgeops rana from Sylvania? Link to comment Share on other sites More sharing options...
Kane Posted September 16, 2020 Share Posted September 16, 2020 The tubercles might suggest this is Eldredgeops crassituberculata. But that may depend on facet count. It could also be a bona fide E. rana, too! "Number of facets ranging from 66 to 89 in eyes of different specimens. Facets separated by flat-topped polygonal ridges. Palpebral lobes as in P. rana. First and second glabellar furrows lacking except on internal molds [...] Remarks.-Phacops rana crassituberculata differs from typical P . rana in the large number of eye facets and in the tuberculation of the glabella. In P. rana the tubercles are relatively small, rounded, and evenly spaced. In P. r. crassituberculata they are large, becoming progressively smaller toward the anterior margin. Some of them are flat-topped in the posterior part of the glabella." (136) Stumm, E.C. (1953). Trilobites of the Devonian Traverse Group of Michigan.
