Species / Tibia Indica

Stromboidea


Original Description of Tibia indica by Dey, 1962, p. 66:

  • "Shell elongate-fusiform; spire moderadelty acute; protoconch (preserved more completely in the paratypes) consisting of about 3 1/2 whorls; subsequent whorls 12, feebly convex; suture linearly grooved; ornamentation very strong on the early whorls, where it consists of crowded with ribs delicate spiral threads between them; but becoming obsolete except for the sinuous growth lines after the 8th or 9th whorl, so that the body-whorl is smooth except for spiral lines, of 2 orders of magnitude, confined to its anterior region; columella very much thickened with a deposit of callus; outer lip also thick at edge, having 4 or 5 denticular projections, canaliculately produced behind and curved along the suture of the preceding whorl; parietal wall bearing a tooth-like projection near the entrance of the posterior canal; anterior canal straight and narrow."

Stratum typicum: Quilon Limestone (carbonate limestone in the Quilon Limestone Formation of India), Burdigalian, Miocene

Locus typicus: Quilon, Kerala State, Malabar Coast, India

Types: holotype no. 16,442, Central Fossil Repository, G.S.I., Kolkata

History and Synonymy

2010

Kulkarni et al., 2010, p. 324 about Tibia indica:

  • "Elongate fusiform shell with acute spire. Only last five whorls preserved, feebly convex, separated by linear suture. At places very weak spiral threads can be detected. The base shows spiral ribs of two orders (figure 2-p3). Rostrum lost, aperture partially preserved. Anterior canal lost; hook-like projection of posterior canal crosses posterior suture of the last whorl."
  • "Occurence: Shell limestone intercalation at the variegated siltstones constituting the lower one-third of the Khari Nadi Formation, on the right bank of the Khari River, 0.5 km NE of Aida."
