Pleuropholis serrata
Taxonomy
Pleuropholis serratus was named by Egerton (1858). It is a compression fossil. Its type locality is Vale of Aylesbury, which is in a Berriasian lagoonal/restricted shallow subtidal horizon in the United Kingdom.
It was corrected as Pleuropholis serrata by Woodward (1919).

| P. M. G. Egerton 1858 | The specimens are for the most part so fragmentary that I have found it necessary to compile the specific characters from the examination of several individuals. The most
perfect specimen (the only one indeed which conveys the form of the fish) is represented in the accompanying Plate, Fig. 5. The head and tail are both imperfect, and the body is a mere impression, the counterpart of which has, unfortunately, not been preserved. This Pleuropholis resembles the other members of the genus in the arrangement of the scales and the disposition of the natatory organs. It differs in its more massive proportions, and in having the posterior edges of the scales serrated. The body is short and deep, compared with the other species resembling in general outline the Pholidophori. The dorsal line is nearly straight, the ventral line rounded. The head as seen in the specimen figured No. 7 is small. The mouth opens upwards, and appears to be edentulous. In this character, and in the position of the orbits and form of the opercular flap, it is so like the head of a Leptolepis, that apart from other evidence it might be plausibly assigned to that genus. The pectoral fins seen in the same specimen are of small size, containing about ten rays. the ventral fins are deficient in all the specimens ; the point of attachment, however, of these organs is seen, in Fig. 5 to have been nearly medial. The dorsal and anal fins, as in the other species of the genus, are opposite to each other, and very similar in form and size. The base of the tail is broad, and the scales do not extend so far on the upper lobe as in Pleuropholis attenuatus and longicaudus. |
