Zosterogrammidae

Zosterogrammidae is an extinct family of millipedes containing three genera, each with a single species. Fossils are known from the Czech Republic, Scotland, and the USA. Zosterogrammidae constitutes the sole family of the order Zosterogrammida.

Description

Zosterogrammids have broad heads, 20 to 32 body segments, with a body tapering towards the head and rear. The dorsal plates of each segment are very broad and the rear portion of each is segment ornamented with lines. Size ranges from 26 millimetres (1.0 in) to 55 millimetres (2.2 in) in length. Superficially they are similar to the living Polyzoniida in body proportion.[1]

Taxonomy and distribution

Zosterogrammidae is placed in its own order, Zosterogrammida. Zosterogrammida is considered incertae sedis (uncertain placement) within the millipede subclass Chilognatha.[1]

gollark: The broader issue is that you have alienated a bunch of the community by imposing the noncompromise earlier.
gollark: As I said, I consider that compromise fine with regards to the specific issue it is actually addressing.
gollark: I don't actually have any authority whatsoever beyond helper powers and control of ██% of the bots here, really.
gollark: Except you just unilaterally came up with that initial statement, so if I wanted to (and I totally do) I could reinterpret that as you demanding some stuff for nothing in return.
gollark: Which is somewhat reduced by you vaguely compromising, I guess.
