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

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

Geological Range:
Last occurrence (top): at top of Maastrichtian Stage (100% up, 66Ma, in Maastrichtian stage). Data source: Lees & Bown 2005 - consistently present to end Cret
First occurrence (base): within Cenomanian Stage (93.90-100.50Ma, base in Cenomanian stage). Data source: Burnett 1998
