Figure 1

Holotype specimen (ELEL-SJ080744) of †Lenisambulatrix humboldti gen. et sp. nov. (a) Part showing paired thick lobopods (arrowheads) attached to the trunk. Asterisk indicates a body terminus interpreted as the anterior end. (b) Counterpart showing lobopods (arrowheads) largely preserved as carbonaceous films. Annuli are evident on bent appendages. (c) Composite interpretive drawing of part and counterpart. Appendages in pale grey; trunk in light blue; sediment escarps indicated by comb-like lines; uncertain boundaries by dashed lines. (d) Close-up of the almost featureless anterior end and an incomplete appendage. (e) Distal part of the second right lobopod showing a bent posture and composite imprint of annuli. (f) Proximal part of the sixth right lobopod attached to the trunk. (g) Close-up of the flexed third left lobopod with evident annuli. (h) Close-up of trunk and its presumed anterior extension. Abbreviations: ae, presumed anterior end; an, annuli; at, attachment sites of lobopods; bp, associated brachiopod shell; la1–la5, left lobopods 1 to 5; ra1–ra9, right lobopods 1 to 9; tr, trunk. Scale bars: 5 mm (ac); 1 mm (dh).
