Zeugrhabdotus petrizzoae


Classification: Mesozoic -> Eiffellithales -> Chiastozygaceae -> Zeugrhabdotus -> Zeugrhabdotus petrizzoae
Sister taxa: Z. acanthus, Z. angelozziae, Z. bicrescenticus, Z. biperforatus, Z. blowii, Z. burolletii, Z. burwellensis, Z. clarus, Z. cooperi, Z. diplogrammus, Z. elegans, Z. embergeri, Z. erectus, Z. fissus, Z. fluxus, Z. howei, Z. kerguelenensis, Z. moulladei, Z. noeliae, Z. petrizzoae, Z. praesigmoides, Z. reticulatus, Z. scutula, Z. sigmoides, Z. simplex, Z. sisyphus, Z. streetiae, Z. trivectis, Z. xenotus, Z. sp.,

Distinguishing features: Medium-sized unicyclic Zeugrhabdotus with a central area spanned by a broad, disjunct, transverse bar. The bar is usually brighter than the rim in LM XPL and formed from two plain blocks divided by a median suture; the two blocks are offset at each end of the bar.

Citation: Zeugrhabdotus petrizzoae Bown, 2005
Rank: Species

Distinguishing features: Medium-sized unicyclic Zeugrhabdotus with a central area spanned by a broad, disjunct, transverse bar. The bar is usually brighter than the rim in LM XPL and formed from two plain blocks divided by a median suture; the two blocks are offset at each end of the bar.


Morphology remarks: The blocks making up the bar are brighter and blockier than those of Zeugrhabdotus diplogrammus, and offset at their ends.
