Phylum Arthropoda von Siebold 1848 View in CoL View at ENA Class Marrellomorpha Beurlen, 1930 Family Mimetasteridae Birenheide, 1971 Genus Furca Fritsch, 1908
Type species: Furca bohemica Fritsch, 1908 , Sandbian , Late (previously interpreted as Middle) Ordovician, Bohemia, Czech Republic .
Emended diagnosis.—Small to medium sized arthropods characterized by a subtrapezoidal cephalic shield with three pairs of prominent primary spines: anterolateral, mediolateral, and posterolateral. Anterolateral spines of variable length and degree of curvature. Mediolateral spines long and strongly curved posteriorly. Posterolateral spines long and weakly curved. Outline of cephalic shield with fringe of secondary spines (modified from Chlupáč 1999a: 81).
Remarks.—The diagnosis of this genus has been emended to account for novel observations of F. bohemica made herein, and for observed features in, as yet, formally undescribed species from the Ordovician of Morocco that might be referable to this genus ( Van Roy 2006; Van Roy et al. 2010).
