Foxaspis (Шаблон:IPA-all) (meaning "fox shield") is a genus of duyunolepidid galeaspid from the early Devonian (Pragian stage) Xiaoshan Formation in Guangxi, Southern China. The type and only species is F. novemura, known from two well-preserved specimens.[1]
Discovery and naming
Foxaspis is known from two specimens that were described in 2023 by Gai et al. The holotype, IVPP V30958.1a-b consists of a complete headshield articulated with a body and tail. The paratype, IVPP V30958.2-3, consists of an incomplete headshield and exceptionally preserved tail.[1]
The generic name, "Foxaspis" (Шаблон:IPA-all), is derived from the English word "fox" and the Greek word "aspis", which roughly translates to "shield", meaning the generic name translates to "fox shield". The specific name, "novemura" (Шаблон:IPA-all), derives from the Latin words "novem", which translates to "nine," and the suffix "-ura" which refers to the tail, meaning the specific name translates to "nine tails". It was named as such after the nine-tailed fox, a mythical beast mentioned in the Shanhai jing.[1]
Description
The tail of Foxaspis is notable, being asymmetrical with nine thin projections covered in scales. These spines may have been covered in a fin web. The tail of Tujiaaspis, a closely related galeaspid, lacked these structures and was generally symmetrical. Galeaspids like Foxaspis and Tujiaaspis were likely relatively fast swimmers compared to other contemporary jawless and jawed fish.[1]
