Dietericambria
extinct genus of pentastomid
Dietericambria is an extinct genus of Cambrian pentastomids from the Henson Gletscher Formation of Greenland. It is the oldest known pentastomid, being at least 15 million years older than the forms recorded from the Orsten. The genus contains a single species, Dietericambria hensoniensis.
Description
Dietericambria was at least 1.2 mm long, with cylindrical segments. (Due to it only being known from fragmentary specimens, any lengths are purely estimates.) It resembles Aengapentastomum, however it has much smaller, unsegmented head limbs. Dietericambria also has an unusual complex of flanges on the ventral surface of the head. The trunk seems to have had limbs, with their sockets being preserved, however their shape is unknown. Unusually, instead of the lateral position of Orsten pentastomids, these limbs are positioned ventrally, similar to that of tardigrades. While hooks similar to the cephalic hooks of modern pentastomids are known from the same formation, they were likely from much larger forms, possibly adults of the species. The position of the mouth is unknown, and while the circular pillar within the flange complex does appear to be a mouth, further examination shows it has the same papillae as the rest of the integument.
Begin with the source’s own compact description: “Dietericambria” is extinct genus of pentastomid. The dossier treats that line as a proposition to test through Dietericambria, extinct and genus, not as a finished interpretation.
Why this record matters
The phrase “extinct genus of pentastomid” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 22, 2025. The linked authority identifier is Q131355395. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
