Summary
| Description |
English: Appendage morphology of the naraoiid type species Naraoia compacta (Walcott, 1912). A–B, part and counterpart of USNM 83945B. C, close-up of exopods 8–11 on the right-hand side of part (white box, A); white arrow indicates position of individual exopod paddle. D, close-up of appendages 5–8 on the left hand side of counterpart (white box, B) with exceptionally well-preserved endopods. E–F, part and counterpart of lectotype USNM 57687. G, close-up of the third biramous appendage of the right-hand side of the counterpart (white box, F) exhibiting imbricating exopod paddles. H, exopods on the left hand side of USNM 189202, individual exopod paddles are discernible as well as elongate exopod shafts and expanded terminal lobes. Abbreviations: 1–5, podomeres; BA, basis; EP, exopod paddle; ES, exopod shaft; LA, left antenna; RA, right antenna; SS, possible spinose setae; TC, terminal claw; TL, terminal lobe. Translucent orbs surrounding endopods in B and D are air bubbles formed through emersion in fluid. Scale bars represent: 10 mm (A, B, E, F); 1 mm (C, G); 2.5 mm (D). |
