From: Soft tissue preservation in a fossil marine lizard with a bilobed tail fin
(a) Photograph and (b) interpretative drawing. Note near-perfect articulation of skeletal elements and virtually intact outline of soft tissues. Note also how the position of the pisiform expands the fin surface and how the anterior digits intimately follow the leading edge of the paddle, thereby contributing to a semi-streamlined parasagittal profile similar to that of sectioned ichthyosaur and porpoise fins (cf. ref. 60). Scale bar, 5 cm. co, coracoid; pf, pisiform; r, radius; ul, ulna; I–V, digits 1–5.
