Figure 3From: Arthroaspisn. gen., a common element of the Sirius Passet Lagerstätte (Cambrian, North Greenland), sheds light on trilobite ancestryTergite articulations of Arthroaspis bergstroemi n. gen. n. sp. A. MGUH 30400, specimen with cephalon and two articulated thoracic segments; A 1 (dorsal aspect); A 2 (ventral aspect); B. MGUH 30407 (pt), specimen with tergites tilted relative to each other, indicating tergite articulations interconnecting tergites along their entire width. Inner lamella is preserved (dorsal aspect); C. MGUH 30390 articulated thoracic tergites and appendages, tergites partially disarticulated (dorsal aspect); D. MGUH 30402 two adjacent tergites articulated at the half-rings only (ventral aspect); E. MGUH 30389, lateral gape of adjacent tergites, with narrow marginal rim on tergites and displaced distal lobe of exopod (dorsal aspect).Back to article page
