Source-derived summary

Onychodontiformes (also known as Onychodontida and Struniiformes) is an order of prehistoric sarcopterygian fish that lived during the Devonian period. The onychodontiforms are generally regarded as early-diverging members of the coelacanth lineage.

Phylogeny

The following cladogram is adapted from Mondéjar-Fernández (2020).

Editorial summary

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2020—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Onychodontiformes, order and fishes.
Editorial analysis

Why this record matters

“Onychodontiformes” is worth following because a concise public description often conceals a longer documentary argument. Here, Onychodontiformes, order and fishes provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 20, 2026. The linked authority identifier is Q137818. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
