Species / Alaria Rudis
Original Description of Alaria rudis by Moore, 1867, p. 542:
Comment Moore, 1876, p. 542: "The surface of the only example I possess appears smooth; but probably it had originally fine transverse striae, which may have been abraded. The outer lip is concealed, so that it cannot be seen whether it possessed digitations. For this reason it is, with a little hesitation, placed in this genus.
Locus typicus: Brocastle, Great Britain
Stratum typicum: "The coralliferous Liassic conglomerate of Brocastle", Sinemurian, Jurassic
