Fig. 2 in Morphology and developmental traits of the trilobite Changaspis elongata from the Cambrian Series 2 of Guizhou, South China
Fig. 2. Major anterior-posterior body divisions measured on oryctocephalid trilobite Changaspis elongata Lee in Chien, 1961 (D14 with 14 thoracic segments, JLZ-160-1006). A line along the sagittal axis was constructed on the image of each specimen and for each segment a line was then placed transversely to this, linking the articulating processes at the fulcral boss (the point abaxially marginal to the fulcrum). The intersections of these lines with the sagittal axis were used to calculate the length of each thoracic segment i (LTSi). LTS2 is shown as an example. Thorax plus pygidium together constitute the trunk. Cephalon, thorax and pygidium make up the body. BOL, body length; TRL, trunk length; CEL, cephalic length; LTH, length of thorax; PYL, pygidial length; LTSi, length of each thoracic segment i.
Fig. 2 in An enigmatic, possibly chemosymbiotic, hexactinellid sponge from the early Cambrian of South China
Fig. 2. Plot of maximum sponge diameter (measured across most distant two points on outer surface) versus maximum width (in millimetres) for the available specimens, with intercept set to 0 and a quadratic correlation plotted with regression coefficient R2 = 0.997. Largest two specimens are incomplete, and measurements are approximate; assume errors in d of up to 5 mm for these two only.

Fig. 3. Interpretative reconstruction of hexactinellid−like sponge Decumbispongia yuani gen. et sp. nov. Internal structure is hypothetical and illustrates a possible canal structure allowing ventilation of interior from convex outer surface (see text for discussion), with exhalent canals on concave, inner surface. Internal spiculation, if any, unknown.
