PennyT. Posted June 22, 2013 Share Posted June 22, 2013 Folks, is this little guy Bumastoides milleri? It's 1/2 inch long and a little more than 1/4 inch wide. From my Grant County, Wis trip so Platteville/MIfflin. thanks Link to comment Share on other sites More sharing options...
piranha Posted June 23, 2013 Share Posted June 23, 2013 Hi Penny, Bumastoides has a broad indistinct thoracic axis. This one looks more like Isotelus based on the axial-pleural ratios. Link to comment Share on other sites More sharing options...
PennyT. Posted June 23, 2013 Author Share Posted June 23, 2013 Piranha, thanks for the correction. I'm just glad it's a trilobite because at first I thought a brachiopod was on top of a trilo fragment! Link to comment Share on other sites More sharing options...
Caleb Posted June 23, 2013 Share Posted June 23, 2013 Isotelus simplex is the species. This trilobite has 8 thoracic segments and yours is showing four. There may be more of him under the matrix. 2 Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...
