Fig. 2

Fossil under a white light and b laser-stimulated fluorescence. c Close-up of reticulate and scutellate scales on digit IV, with arrows indicating exemplary spiculate reticulate scales. d Interpretive drawing, where solid lines indicate preserved structural boundaries, and dashed lines represent assumed or completed boundaries. Note the arthral arrangement of toe pads in which the interpad creases do not align with the phalangeal joints.
