Texoceras
genus of molluscs (fossil)
Texoceras is an extinct ammonoid genus in the monotypic goniatitid subfamily Texoceratinae, included in the family Adrianitidae. These were shelled cephalopods more closely related to squids, belemnites, octopuses, and cuttlefish than to nautiloids from which they are derived.
Texoceras, named and described by Miller & Furnish in 1937, has an involute subglobular shell, like Adrianites, with a narrow deep umbilicus in the middle, but with a reticulate surface and a suture that forms 14 rounded lobes.

The public source identifies “Texoceras” as genus of molluscs (fossil). This brief keeps that definition visible, then builds a research path around Texoceras, genus and molluscs.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Texoceras”, the useful work is to connect “genus of molluscs (fossil)” to the records capable of establishing context and consequence.
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 Nov 18, 2024. The linked authority identifier is Q16993031. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1937 and 1957.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
