Bradley Flynn Posted July 7, 2020 Share Posted July 7, 2020 So I went on another scouting mission today. New spot is looking like it will be amazing when I spend a day there. Only spent about an hour looking for fossils and found some interesting stuff. Also my first trilobite Cephalon!!! So stoked!! It has a chip on the front and I think the other eye could be in the matrix. The matrix is a lot harder than what I have found fossils in before, also seems like the fossils are much better preserved. 6 Link to comment Share on other sites More sharing options...

FossilDAWG Posted July 7, 2020 Share Posted July 7, 2020 That spot has amazing potential! And, the detail on that eye is fantastic! Don Link to comment Share on other sites More sharing options...

Bradley Flynn Posted July 7, 2020 Author Share Posted July 7, 2020 @piranha I've referred to the literature you sent me and have come to the conclusion that the Cephalon and pygidium are Gamonedaspis boehmi. What do you think? They where found almost on top of each other. If so the thorax could also be in the same spot. Link to comment Share on other sites More sharing options...

The paired tubercles on the pygidial axis is a match with: Gamonedaspis boehmi The eye of Gamonedaspis boehmi has fewer lenses with up to 8-9 lenses in the central files across 30-32 vertical lens files. Instead this eye matches with Francovichia clarkei which has up to 15 lenses in the central files across 50 vertical lens files.

Confirmation? @piranha All of the subspecies are synonymized within Burmeisteria herscheli and Burmeisteria notica. The name 'subfusiformis' used by Cooper on figure 15 is a typo referring to: Homalonotus (Burmeisteria) herscheli var. nov. fusiformis Reed 1925 from Cooper 1982: "The var. fusiformis was created by Reed (1925a) for the pygidium figured by Lake (1904) (Fig. 15A-B herein) and, as the varietal name implies, distinguished by its subfusiform outline. While this variant is distinctive, no further individuals have been forthcoming and the characters seem to be those of an aberrant individual. As such, the perpetuation of Reed's name is tantamount to naming individuals and it is not used here."
