Elonichthyidae ALDINGER, 1937


Elonichthyidae ALDINGER, 1937 Elonichthys ” sp.

Isolated scales and small teeth are the most abundant fish remains. The scales (MHK 82591, 82594, 82615) possess sculptures of diagonal ridges. The longest ridge pass diagonally from the anterodorsal corner to the posteroventral corner of the scale, and it divides the outer surface of the scale into the posterodorsal and anteroventral halves. Diagonal ridges similar to the ridges above terminate in pointed processes on the posterior margin of the scale. The ridges below the diagonal ridge do not reach the posterior border of the scale. It conforms to the sculpture of scales described by Štamberg (2016) as “ Elonichthys ” sp .

The teeth are slender and sharply pointed (MHK 82591, 82616, 82625) with a distinct acrodentine apex (Pl. 2, Fig. 2). They are one or two millimetres long. Some teeth exhibit well preserved, lanceolate microtubercles on their surface (Pl. 2, Fig. 3), despite the fact that the surface of the teeth is often abraded due to transport processes. An isolated crescent shaped nasal bone with longitudinal ridges (MHK 82611) completes the set of “ Elonichthys ” sp. remains .
