Scale GIT 580 - 16, seen in lateral view (Fig. 7 B), is more typical of a head to cephalopectoral scale with a series of rounded undulations around the gently rounded crown. ħe upper surface is smooth. ħe base is not larger than the crown but extends slightly anteriorward		1														https://treatment.plazi.org/id/493F87AAFF936227689AFBC4FD84F951#71FE3CE1FF936225683FFAA7FD59FE82				MaterialCitation

A smaller extension to the lower left might be an artifact or a further lower lappet on that side. ħe posterior parts are not well preserved but probably extended well beyond the mid-posterior point of the crown. ħere is a wide shallow grooved neck separating the crown from the relatively shallow base. As the basal view is not available the pulp opening type is unknown. ħe base is slightly thickened anteriorly into a short downwards-projecting narrow spur, which is broken off at the tip. Specimen GIT 580 - 11 (Fig. 7 D) is generally similar although wider across the scale than in 580 - 10. ħe projections extend from the median part of the crown as well as being placed on a short narrow lateral lappet or ridge on both sides. ħe extended parts are better preserved and number 9 or 10 with the posterior mid-point. ħe neck is wider and the base slightly shallower		1														https://treatment.plazi.org/id/493F87AAFF936227689AFBC4FD84F951#71FE3CE1FF9362276AEBFC3BFDC5FEC3				MaterialCitation

It has a slightly oval central tubercle, placed asymmetrically, and around it smaller asymmetrical tubercles, forming three rows, except at one of the sides. At the opposite side the tubercles are partly laterally compressed and lamellar. Tubercles have narrow smooth ridges, which are most numerous on the central tubercle (up to 13). ħe ridges end at the sharp tips of tubercles. ħe second remain (Fig. 8 B; GIT 580 - 25) is rather fragmentary and shows spongy bone with four broken tubercles on it. Ornament of the tubercles is rougher than that of the previous specimen. ħe ridges are in cross section less sharp in comparison with those of the specimen GIT 580 - 22. One of the ridges bifurcates at its proximal end. Apices of the tubercles were differently directed. ħe specimen could be a fragment of a larger spindle-like element		1														https://treatment.plazi.org/id/493F87AAFF8E623B6ABAFAE6FD85FCDE#71FE3CE1FF8F6239683FFEBCFDADFBF8				MaterialCitation
