Taxonomy
Coosina kindlei was named by Westrop (1992) [Coosella helena LOCHMA1N9,38, p. 468, PI. 57, fig. 9 [only; figs. 1 0 -
15 = Coosella helena].
Coosia sp. LOCHMA1N9,38, p. 468, P1. 57, fig. 39.]. It is not extant. Its type specimen is GSC 100939, a cephalon/head (cranidium). Its type locality is MP3 / PP1, which is in a Dresbachian open shallow subtidal packstone/packstone in the Petit Jardin Formation of Canada.

| S. R. Westrop 1992 | A species of Coosina with firmly impressed axial and preglabellar furrows. Frontal area equally divided into downsloping preglabellar field and convex border by well-defined border furrow. Axis occupies about four-fifths of pygidial length and consists of three axial rings plus terminal piece. Pygidial border gently concave.
Description. Tapered, anteriorly rounded glabella weakly convex and raised only slightly above adjacent areas of cheeks; outlined by firmly impressed axial and preglabellar furrows and occupies about three-quarters of cranidial length. Three shallow lateral glabellar furrows evident on parietal surfaces: 1s and 2s geniculate, whereas 3s convex. Occipital furrow wide and bowed gently forward medially but narrows and curves forward near axial furrows. Palpebral lobe located opposite 2p glabellar lobe and separated from wide, weakly arched cheek by broad, shallow palpebral furrow. Frontal area equally divided into downsloping preglabellar field and convex border by well-defined border furrow. Narrow posterior border separated from cheek by broad, firmly impressed posterior border furrow. Anterior branches of facial suture subparallel before swinging abruptly inward along anterior cranidial margin; posterior branches diverge backwards in a weakly sigmoid curve. Parietal surfaces finely pitted, with the addition of fine, transverse ridges on anterior border. Free cheek lacks genal spine and possesses convex lateral border separated from convex cheek by deep border furrow. External surface cames prosopon of fine granules, with faint caecal markings on cheek; border cames fine transverse ridges. Pygidium sub-semielliptical in outline, with length about threefifths of width, and posesses a very weak median embayment along posterior margin. Axis occupies about four-fifths of pygidial length and consists of three axial rings plus terminal piece. Convex pleural fields crossed by four pairs of broad, well-defined pleural furrows and slope down to a relatively narrow, concave border. External surface cames prosopon of fine granules; internal molds finely punctate. |
