Data from: The oldest notostracan (Upper Devonian Strud locality, Belgium)

A new notostracan crustacean, Strudops goldenbergi gen. et sp. nov., is described from the well-preserved terrestrial arthropod fauna of the Upper Devonian of Strud, Belgium. The fossil notostracan bears a close resemblance to modern notostracans in possessing a large, simple head shield covering almost half of the whole body, a set of phyllopodous thoracic appendages and a legless posterior abdomen with a telson bearing a caudal furca. The differentiation and relative size of mouthparts and limbs suggest that these specimens are all adults. The notostracans described herein are the earliest clear members of the total group Notostraca.

本研究记述了采自比利时斯特鲁德（Strud）晚泥盆世保存完好的陆生节肢动物化石群中的全新背甲目（Notostraca）甲壳动物新属新种——斯特鲁德普斯·戈尔登伯格（Strudops goldenbergi gen. et sp. nov.）。该化石背甲目类群与现生背甲目类群形态高度相似，具有覆盖近半躯体的大型简单头盾、叶足型胸附肢，以及无附肢的后腹部，其尾节（telson）带有尾叉（caudal furca）。通过口器与附肢的分化程度及相对尺寸可推断，本次研究的所有标本均为成年个体。本次记述的背甲目类群是背甲目总群（total group Notostraca）中已知最早的确凿成员。
