Development of the caudal-fin skeleton of the beloniform Hyporhamphus cf. limbatus (PMJ PISC-1857). a SL = 3.65 mm; b SL = 7.23 mm; c SL = 10.15 mm; d SL = 11.91 mm. Abbreviations: EU, epural; HA, haemal arch; HS, haemal spine; LHP, lower hypural plate; NA, neural arch; NO, notochord; PH, parhypural; PU, preural centrum; UC, ural centrum; UHP, upper hypural plate. Arrow points at developing uroneural. Scale bar: 200 μm
