English: Various fossils pertaining to the holotype of the Triassic ichthyosaur Toretocnemus (originally Leptocheirus, also Merriamia) zitteli. This image is derived from plate 23 in Merriam (1903), done by an uncredited artist. The arrangement of the individual figures has been modified from the original (most notably, figures 3 and 4 were swapped to minimize confusion).
