Tetrapodorhabdus decorus


Classification: Mesozoic -> Podorhabdales -> Axopodorhabdaceae -> Tetrapodorhabdus -> Tetrapodorhabdus decorus
Sister taxa: T. coptensis, T. decorus, T. shawensis, T. sp.,

Distinguishing features: Podorhabdid with central area spanned by relatively high angle diagonal cross bars that bear a large, flaring spine.


Taxonomy:

Citation: Tetrapodorhabdus decorus (Deflandre in Deflandre & Fert, 1954) Wind & Wise 1983
Rank: Species
Basionym: Rhabdolithus decorus Deflandre in Deflandre & Fert, 1954
Synonyms:
Notes & discussion: The combination was initially proposed in Wind & Wise in Wise & Wind (1977) but the original publication was not cited directly hence the proposal was technically invalid and so was proposed again, validly, in  Wind & Wise 1983.
The type species is based on a reworked specimen but the spine structure is so distinctive the identity is not in doubt.

Farinacci & Howe catalog pages: Rhabdolithus decorus * , Ahmuellerella granulata *

Distinguishing features: Podorhabdid with central area spanned by relatively high angle diagonal cross bars that bear a large, flaring spine.


Morphology remarks: Spine has highly distinctive helical appearance in cross polars
