Staurolithites imbricatus


Classification: Mesozoic -> Eiffellithales -> Chiastozygaceae -> Staurolithites -> Staurolithites imbricatus
Sister taxa: << < S. dibrachiatus, S. stradneri, S. dentatus, S. eiffellithoides, S. flavus, S. halfanii, S. minutus, S. ngurumahambaensis, S. quadriarcullus, S. siesseri, S. coroniformis, S. gausorhethium, S. leptostaurus, S. dorfii, S. handleyi, S. imbricatus, S. laffittei, S. lumina, S. mielnicensis, S. mitcheneri, S. angustus, S. mutterlosei, S. zoensis, S. aachenus, S. aenigma, S. dicandidula, S. ellipticus, S. elongatus, S. integer, S. parma, S. sp.,

Distinguishing features: Large species of Staurolithites (c. 7.0 µm) with a narrowly elliptical, diffusely bicyclic rim and a broad axial cross. Both rim and cross display grey interference colours. At 45° to the polarising directions the cross bars display a distinct, median extinction line. The cross bars show patches of brighter interference colours near their junction with the rim.
