Some silicified Middle Silurian rostroconchs (Mollusca) from the Mackenzie Mountains, N.W.T., Canada
A silicified rostroconch fauna is described from strata of Early (late Llandovery) to Middle (Wenlock to early Ludlow) Silurian age in the Mackenzie Mountains. Two new genera, Cassowarioides and Nehedia, and nine new species, Bigalea buskasi, B. tercierae, Bransonia foxi, Cassowarioides perryi, C. s...
