Proetus (trilobite)

Proetus is a genus of proetid trilobite found in Silurian-aged marine strata of Europe.[1][2]

Not to be confused with the mythological figure of the same name or the similarly-named mythological figure Proteus.

Etymology
Comparison of P. concinnus and Ainiktozoon

The generic name commemorates Proetus (Greek: Προῖτος), a mythical king of Argos and Tiryns, son of King Abas of Argo.

Taxonomy
Cladogram of the genera of the subfamily Proetinae, according to Lieberman, 1994, figures 5 and 6[1]

Proetus is the type genus of the order Proetida, and of the family Proetidae. The genus became a wastebasket taxon that held numerous species of similar looking trilobites from the Ordovician to Carboniferous periods. Most of these species have been split off into other genera, leaving only P. concinnus and P. latifrons as the only confirmed members.[1]

Distribution

Fossils of the type species, P. concinnus, are found in Wenlock-aged marine strata of Sweden, Great Britain, Estonia, and Germany. Fossils of the other recognized species, P. latifrons, are found in Llandovery-aged marine strata of Ireland and Great Britain.[1]

gollark: But what if my app needs 85TB of RAM to work?
gollark: Which is probably because of consumer apioidness and its origins in the telecoms world rather than the computing one.
gollark: Which is ultimately because the phone market is terrible and merges software and hardware too much.
gollark: Yes, one of its greatest flaws is that OEMs don't know when to stop idiotically changing things.
gollark: Maybe it was done by the same people who wrote the bad camera app.
