Fig. 10 in The largest arthropod in Earth history: insights from newly discovered Arthropleura remains (Serpukhovian Stainmore Formation, Northumberland, England)

Fig. 10. Details of (a, b) slab Aand (c, d) slab Bwith interpreted sketches of margins showing offset of three-dimensional sand infill from carbonaceous smear. Same tergites on each slab are colour-coded (with reference to prominent tergite shown in white). Cuticular interior shown as full circles with correspondingly shaped carbonaceous smear shown as colour-coded partial circles, indicating consistent 40 cm squeezed offset of infill from cuticle in direction of red bidirectional arrow, associated with synsedimentary deformation. Scale bars 20 cm.
