Examples of putative tadpole body fossils. Photographs are at different magnifications; see corresponding scale bars. a–d – Triadobatrachus massinoti (PIVETEAU, 1936a) (Salientia); basal Triassic, Betsieka, northern Madagascar. Two copies of original holotype specimen, MNHN (Museum National d’Historie Naturelle, Paris, France) F.MAE.126, a split nodule exposing dorsal and ventral surfaces of a nearly complete skeleton preserved as a natural mold; all copies are oriented with head towards top of figure: first pair is replica (epoxy cast) of original fossil showing bones as impressions, in dorsal (a) and ventral (b) views; second pair is negative cast (also epoxy) showing bones in positive relief, in dorsal (c) and ventral (d) views. Interpreted as a metamorphic tadpole by Griffiths (1956, 1963), the unique holotype of T. massinoti now is regarded as being from a young post metamorphic individual (e.g., Rage and Roček 1986, 1989). See Rage and Roček (1989), Roček and Rage (2000), and Ascarrunz et al. (2016) for labelled interpretive drawings and other images. Replicas provided by MNHN and deposited in collections of the Royal Tyrrell Museum of Palaeontology (Drumheller, Canada) as TMP 2008.003.0009 (first pair) and TMP 2008.003.0008 (second pair). Photographs courtesy of G. Housego. e – Palaeospondylus gunni TRAQUAIR, 1890, NHMUK (Natural History Museum, London, England) PV P61846; Middle Devonian,Achanarras Quarry, northern Scotland. Complete skeleton preserved in typical pose and orientation, in this case with body curved, head (directed towards top of figure) and body exposed in dorsal view, and tail twisted such that its left side is exposed and the deeper, ventral portion of tail faces towards top of figure. Note continuous sequence of ring-like vertebrae along central axis of body and tail, and elongate and asymmetric tail fin supported internally by well-developed, bifurcating radials. Suggested to be a tadpole by Dawson (1893) and Jarvik (1980), Palaeospondylus is widely regarded as a larval fish, although its affinities remain controversial (e.g., Johanson et al. 2010 and references therein). See Moy-Thomas (1940) and Forey and Gardiner (1981) for labelled interpretive drawings of other specimens. Photograph courtesy of Z. Johanson. f, g – The Daohugou “tadpole”, CAGS (Chinese Academy of Geological Sciences, Beijing, China) IG01-705; late Middle or early Late Jurassic, Daohugou, Inner Mongolia. Entire slab (f) and close up (g) of fossil; differences in matrix color are because photographs were taken using different lighting. This soft-bodied fossil lacks any indication of internal skeletal tissue. Originally interpreted by Yuan et al. (2004) as a tadpole body fossil (in dorsal or ventral view, with anterior towards top of figure), consisting of a head and body with prominent hind limbs and a thin, straight tail. Reinterpreted by Huang (2013: see his interpretive line drawing on p. 143) as an incomplete, cicadomorph insect (also in dorsal or ventral view, but with anterior towards bottom of figure), consisting of anteriorly projecting rostrum (= “tail” of tadpole), pro- and mid-thorax portion of body (= “head and body” of tadpole), and forelegs (= “hind legs” of tadpole).
