Retecapsa escaigii


Classification: Mesozoic -> Podorhabdales -> Cretarhabdaceae -> Retecapsa -> Retecapsa escaigii
Sister taxa: R. beckii, R. escaigii, R. surirella, R. crenulata, R. angustiforata, R. octofenestrata, R. schizobrachiata, R. incompta, R. ficula, R. sp.,

Distinguishing features: Small to medium-sized cretarhabdids with distal shields that slope in to the central-area, which is spanned by an axial cross with numerous lateral bars (7-8 in each quadrant). Distal shield does not appear to be bicyclic.
