 |  |  |  | Axopodorhabdus albianus
Axopodorhabdus with 3-tiered shield and axial cross bars that flare where they join the rim. Highly diagnostic XPL image comprising birefringent cross bars with median extinction lines that darken at 45 degrees.
|
 |  |  |  | Axopodorhabdus atavus
Axopodorhabdus with narrow rim and narrow axial cross bars.
