The hybodontid type scales from the Malevka and Upa regional stages of the 441 and Berzhetsy-475 cores have a cone-shaped, apically elongated crown with denticulate
ridges separated by longitudinal grooves (Fig.

the blades of the long chaetae are denticulate
, but their number is only evident with a more powerful enlargement].
Antecostal suture on notum I absent, but distinct and denticulate
on nota II-III and abdominal terga I-IX.
For these characteristics and for their curved, fluted, beaklike tip, the type 1 sensilla are also similar to the denticulate
setae described in other decapod shrimp (Bauer and Caskey, 2006), which are much shorter and can be compared to the type 2 sensilla found in large numbers on both flagella.
Rhizomes long creeping, covered with membranous ovate-apiculate scales; rhizome scales comose in distinct grades on dorsal surface, bicolorous with a dark central streak of sclerotic cells and pale margins, which are denticulate
to erose; blade lanceolate to oblanceolate, basally pinnatisect and lobed to pinnatifid distally, with proximal lobe free; laminar scales scattered on abaxial surface and glabrescent on adaxial surface, with round to ovate scales with apiculate or caudate apices, center obscure brown, margins pale brown, fimbriate to ciliate; midribs and secondary veins not visible; sori oblong, with orbicular, peltate scales similar to those in the lamina; spores bilateral, abortive, prominently verrucate.

to crenulate to subentire.

It has some features of the Iguanodontidae teeth noted by Norman and Weishampel (2004); Paul, (2007, 2011) and Norman, (2011, 2013), such as possessing only one replacement tooth per tooth position, the labial surface of the crown is thickly enameled and has a strongly denticulate
margin and is dominated by a very large primary ridge arising from the base of the crown.
Although the CM is stabilized in the spinal canal by the denticulate
ligament, nerve root, and the filum terminale,[sup] there is significant evidence that it moved along the cranio-caudal axis.
