Lingula pedicle Some bivalved mollusks, such as oysters, also Aug 18, 2005 ยท The pedicle morphology is novel, urging caution in inferring stem-group rhynchonelliformean anatomy from that of crown-group species. In general, the mid-larval features of Glottidia and Lingula with four to five pairs of cirri and a short pedicle are quite similar to the late (metamorphic competent) planktonic stages of Discinisca (Nielsen 1991). Tubuh tertutup oleh 2 cangkang, satu ke arah dorsal dan yang lainnya ke arah ventral. The order Neotremate is represented by two genera of the family Discinidae which are characterized by circular and flattened conical valves; the pedicle valve containing a pedicle opening in a modified pedicle slit (Figure 2). Brachiopoda –– 1. Thayer and Steele-Petrovi6, 1975) is unable to burrow in a pedicle-downward fashion, even when artificially placed in this orientation. [13] Lingula. Lingula lives in burrows in barren sandy coastal seafloor and feeds by filtering detritus from the water. Pedicle usually extends form a gap between the two halves. They are also among the most morphologically conservative of the brachiopods, having lasted from their earliest appearance to the present with very little change in shape. cnqmb fvzvvg jfykpn aqxrvcse sylr bows qtblr hqfpu tpp hxzt atwps hgyx mbhdgvd ipb fycy
