Summary
| Description |
English: Details of †Diania cactiformis based on new material. (a) Incomplete, ventrally compacted specimen (ELEL-SJ102058) showing anterior trunk segments terminated by a possible head. Lobopods of another overlying individual are marked by white circles. (b) Close-up of focus area in (a) showing a putative head with lateral spines and modified appendages. Arrowheads indicate trunk spines. (c) Details of anterior structures, including the helmet-like head and a pair of modified appendages. Asterisk (in c, d, e) indicates attachment site of a modified appendage. (d,e) Backscattered electron (BSE) analysis of anterior structures (d) and details (e) of a modified appendage (focus area in d). Dark areas in BSE images suggest soft tissues preserved as organic carbon residues; bright areas suggest pyrites. (f) Interpretative drawing of (c). (g) Distal part of the first right lobopod. Asterisks indicate imprints of spine bases. (h) Second trunk segment showing proximal part of lobopods with annuli. (i) Proximal part of the third left lobopod showing annuli. Abbreviations: an, annuli; he, head; hs, head spine; ma, modified appendage; la1–la3, left lobopods 1 to 3; ra1–ra3, right lobopods 1 to 3; sp, spine; mo, mouth; tr, trunk. Scale bars: 5 mm (a); 1 mm (b–d,f–i); 500 µm (e). |
