Euphoberiida : ウィキペディア英語版 | Euphoberiidae
Euphoberiidae is an extinct family of archipolypodan millipedes known from the Upper Pennsylvanian of Europe and North America. The family includes relatively large millipedes measuring up to long bearing distinctive spines and were the dominant millipedes of the Pennsylvanian.〔Shear, William A. (1997) (The fossil record and evolution of the Myriapoda ). In: Fortey, R. A., Thomas, R. H. (Eds.), ''Arthropod Relationships''. Systematics Association Special Volume 55. Chapman & Hall, London, pp. 211–219〕 ==Description== Euphoberiids are characterized by sets of outward-pointing spines on each diplosegment (body ring), one pair extending laterally (to the sides), the other pair higher on the body. At the base of each lateral spine is an ozopore, or defensive gland opening. Species of ''Acantherpestes'' and ''Euphoberia'' have cylindrical bodies, while those of ''Myriacantherpestes'' are more flattened in appearance.〔
