Images from and modified from Lingjam-Soliar, 2013. Yellow arrows in A-B indicate direction of lighting; direction in B is the same as in C and D. Rectangle 1 is the closeup of the relevant region of the tail, at the break. B, close up of the break in caudal series, with lavender indicating structures of the slab, either deep impressions or reliefs: c, impressions of the continuing caudal series after the "break"; ftm, fine tooling marks, surrounded halo; i, includions, possibly seeds; s, multilobate structures which may indicate large seeds or flower ovaries. Rectangle 2 is shown in C-D; rectangle 3 is the continuation of the features seen in closeup in rectangle 2 and C-D. C, TLS's attempt to describe the break in the tail, shown in dotted lines, and the features in the slab implied to be scales. Resolution may suggest granulation of the overlying matrix, which has been partially removed in C (inset box at top left in C) shows condition prior to preparation which concerns TLS. Rectangle 4 is shown in close up in D. D, TLS is describing the "collagen" cross-hatching and seeming divisions of scale structures from the lumpy relief features. Remember, in C-D, lighting is from the left and slightly angled up to the right. structures of interest Marks on IVPP V12514, specimen referred to Sinosauropteryx sp. (Lingham-Soliar et al., 2007); modifed from Lingham-Soliar, 2013. A-B and C represent two separate sections of the fossil, but both come from the distal section of tail; C, from the proximal end at the break, and A-B from more distal along the series, albeit at lower resolution. Note that lighting is to the top left. CAGS01-IG-gausa-1, holotype specimen of Scansoriopteryx heilmanni Czerkas & Yuan, 2002. Different integument structures are indicate: fil, filaments; sc, scales. "Traditional" reconstruction for Sinosauropteryx prima. Alternate reconstruction of Scansoriopteryx prima, following Theagarten Lingham-Soliar. Diagram of the tail tip of IVPP V12514, referred to Sinosauropteryx sp. by Lingham-Soliar et al., 2007. Black refers to the presence of cracks between subslab sections and vertebrae/shevrons. A, original preservation, with numbers reflecting vertebral sequences by proximality. c, "collagen;" s, "scales;" ?, unknown, unremarked. B, my interpretation of these structures, with reds to oranges reflecting gradient of integumental preservation (red, filaments; orange, varying degrees of filament-less regions of the bedding plane or prepared regions). f, filaments; i,. inclusions or impressions of foreign objects, possibly fruits, seeds, or flower ovaries; tf, trace fossils? also, possibly preparation marks; tm, tooling marks. http://qilong.wordpress.com/2013/03/15/the-fisherman-the-sinosauropteryx-preview/ http://qilong.wordpress.com/2013/03/15/the-fisherman-the-sinosauropteryx-preview/#comments Fri, 15 Mar 2013 10:20:06 +0000 Jaime A.
