Figure 3 in First record of the chancelloriid Allonnia from the middle Cambrian Wheeler Formation (Drumian, Miaolingian) of western Utah
Figure 3. Details of Allonnia cf. Al. tintinopsis, FHPR 11423, from the Wheeler Formation of western Utah. A) SEM image of several sclerites, showing abapical and adapical horizontal rays and absence of central or principal rays, confirming 3+0 arrangement. B) SEM image of sclerite central in A, showing apparent articulatory facets on a displaced adapical horizontal ray between abapical horizontal rays of presumably the same sclerite. C) SEM image of oval-shaped area of high carbon content (dark gray to black) near transition between orange and dark gray preservation areas of the scleritome. D) SEM image of more apically-placed dark gray preservation area of scleritome showing apparent very elongate rays but relatively low elemental contrast between the fossil and matrix. E) SEM image of the basal part of the scleritome showing very elongate sclerite rays preserved as impressions in the matrix rather than by elemental contrast. F) View of scleritome with areas of details A–E indicated. Scale bar = 5 mm. Scale bars for A–E in each image. Abbreviations: abhr, abapical horizontal ray; adhr, adapical horizontal ray; af, articulatory facet; er, very elongate ray.
