Figure 6 in A new Late Eocene cassiduloid (Echinoidea) from Yorke Peninsula, South Australia

Figure 6. Comparative drawings of A, Late Eocene Rhynchopygus? janchrisorum sp. nov. from Yorke Peninsula, South Australia; B, Late Cretaceous (Late Maastrichtian) R. donetzensis from the Severny Donetz Basin, Ukraine (adapted from Smith and Jeffery, 2000); C1, Late Cretaceous (Late? Santonian) R. marmini from La Richardière, Dissay, France; C2, posterior profile of Late Cretaceous (Late Campanian) R. marmini from near Royan and St Palais-sur-Mer, France. Based on published illustrations, latter profile typical of Maastrichtian R. marmini specimens in general. Scale bars 5 mm.图6 对比绘图如下：A为产自南澳大利亚约克半岛的晚始新世暂归吻海胆属？（Rhynchopygus）的janchrisorum 新种（sp. nov.）；B为产自乌克兰北顿涅茨盆地的晚白垩世（晚马斯特里赫特期）顿涅茨吻海胆（R. donetzensis，改编自Smith与Jeffery，2000）；C1为产自法国迪赛拉里什里耶尔化石点的晚白垩世（晚？桑托期）marmini吻海胆（R. marmini）；C2为产自法国鲁瓦扬附近与圣帕尔勒叙尔梅尔的晚白垩世（晚坎潘期）marmini吻海胆（R. marmini）的后部轮廓。基于已发表的插图，该后部轮廓总体上可作为马斯特里赫特期marmini吻海胆标本的典型特征。比例尺为5毫米。
