Fig. 1: Different styles of preservation and morphology of Vermilituus gregarius.
From: Symbiotic fouling of Vetulicola, an early Cambrian nektonic animal
a, b Holotype, YKLP 13079a, flattened specimen showing U-shape morphology, under cross-polarised light (a) and fluorescence light (b). c Paratype YKLP 13084, partial 3D with well-preserved annulation, J-shape morphology. d, h YKLP 13086 under direct light (d) and fluorescence light (h), white arrow shows possible soft tissues. e Paratypes YKLP 13082 and 13083, preserved in 3D with annulation visible proximally: sinusoidal shape and J-shape morphology, respectively (the latter is broken distally and shows sediment fill). f Paratype YKLP 13085, partial 3D with well-preserved annulation, sinusoidal morphology. g, i–k Scanning electron microscopy images. g YKLP 13087 with J-shape morphology. i, j YKLP 13088, boxed area in “i” shows possible paired soft tissues at the termination, magnified in “j”. k YKLP 13089, with possible paired soft tissues at the terminal end. Scale bars: a–d, g–i, k, 500 μm; e, f, 1 mm; j, 200 μm.
