Palaeomylus
Extinct genus of fish
Palaeomylus (meaning 'ancient grinder') is an extinct Devonian ptychodontid placoderm fish.
There are seven species accepted in this genus:
Palaeomylus hussakofi Bryant, 1935 Palaeomylus lunaeformis Hussakof & Bryant, 1919 Palaeomylus minor Bryant, 1935 Palaeomylus predator Eastman, 1898 Palaeomylus crassus (Newberry, 1873) Palaeomylus frangens (Newberry, 1878) Palaeomylus greenei (Newberry, 1889)
Etymology
The generic name is derived from Greek (Palaeo, meaning "ancient") and (mylos, meaning "grinder").
Not to be confused with the junior homonym Palaeomylus (Meng, Wyss, Hu, Wang, Bowen & Koch, 2005), which is an early diverging member of the mammal group Glires.
Discovery
P. greenei, P. crassus, and the type species P. frangens were originally classified as a species of Rhynchodus, before being moved to a new genus, Palaeomylus, in 1891. The first was found in Wisconsin, while the latter two species were found in Ohio. P. predator was found near Gerolstein, Germany.
The public source identifies “Palaeomylus” as extinct genus of fish. This brief keeps that definition visible, then builds a research path around Palaeomylus, Extinct and genus.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Palaeomylus”, the useful work is to connect “extinct genus of fish” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 26, 2026. The linked authority identifier is Q127033735. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1935, 1919, 1898 and 1873.
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.
