other taxa (他の分類群)
They appear to be closely related to other taxa of uncertain affinity, including the microconchids, trypanoporids and tentaculitids.
However, they do not share many of the adaptations that these other taxa possess, and some researchers are not convinced by this hypothesis.
Riggs considered the differences from other taxa significant enough to name a separate family, Brachiosauridae, of which "Brachiosaurus" is the namesake genus.
The taxa within the subfamily Lycoteuthinae are:
This has however led to several unreliable results and polyphyletic taxa within "Oncidium".
Stable isotope probing (SIP) is a technique that can be used to determine the active metabolic function of individual taxa within a complex system of microbes.
The genus' sister taxa is the extinct Priscaenigma.
"Pachycondyla" is regarded as the sister taxa to "Dinoponera".
The species has no sister taxa.
