Percivalia fenestrata


Classification: Mesozoic -> Eiffellithales -> Rhagodiscaceae -> Percivalia -> Percivalia fenestrata
Sister taxa: P. arata, P. bullata, P. dunkleyjonesii, P. fenestrata, P. hauxtonensis, P. howardii, P. imperfossa, P. pearsonii, P. pontilitha, P. porosa, P. sp.,

Distinguishing features: Loxolith coccoliths with narrow outer cycle and wide central area filled with a granular plate. The plate is distinctly smooth and birefringent in XPL and crossed by curving extinction lines.
