I.—Preliminary Note on a New Specimen of Squatina from the Lithographic Stone of Nusplingen, Würtemberg

Published online by Cambridge University Press:  01 May 2009

Extract

Several specimens of extinct species of the angel-fish or monk-fish (Squatina) are already known from the Lithographic Stone (Lower Kimmeridgian) of Bavaria, Würtemberg, and France; and some of these are in an admirable state of preservation. Two forms are clearly distinguishable—the one a small fish not more than 0·15 m.inlength, with a dense armour of rounded dermal tubercles on the anterior border of the head and each of the paired fins, and upon the lateral aspect of the tail; the other a comparatively large fish, attaining a length of at least a metre, without any similar development of the dermal tubercles, either in the regions mentioned or on any other part of the body.
