解説20210202 Chasmataspidida size comparison.png | English: Size comparison of chasmataspidids ( Arthropoda: Chelicerata: Chasmataspidida). Species with only partially revealed or unknown Prosomal/opisthosomal regions (e.g. Nahlyostaspis bergstroemi, Skrytyaspis andersoni, Kiaeria limuloides) are not included in this diagram. Silhouette of appendages ommited. 日本語: カスマタスピス類( 節足動物: 鋏角類: カスマタスピス類)のサイズ比較図。前体/後体が局部のみ判明もしくは不明の種類(例えば ナリョタスピス・バーグストロエミ Nahlyostaspis bergstroemi、 スクリティアスピス・アンダーソニ Skrytyaspis andersoni、 キアエリア・リムロイデス Kiaeria limuloides)はこの表に含まれない。付属肢のシルエットは省略される。 References 参考文献: - Dunlop, Jason A.; Anderson, Lyall I.; Braddy, Simon J.
