Squamation There are 35 vertical rows of scales along the lateral line of the body.Similar to other peltopleuriforms,the lateral line scales are greatly deepened in the anterior flank region.The deepest scales are eight times deeper than long.The sensory pores are present on four(the 2nd,5th,14th and 16th)lateral line scales in the holotype.In addition to the median scales,one and three horizontal rows of scales are present respectively above and below the lateral line scales at each side of the anterior flank region.In the caudal region,two and five horizontal rows of scales are present respectively above and below the lateral line scales.The outer surfaces of the scales are smooth.The posterior margins of scales in the anteroventral region of the body have many small serrations,and those in other regions are nearly straight(Fig.2B,D).Peg-and-socket articulations are present as in other peltopleurids.A comparison of the squamation pattern of Peltopleurus species is presented in Table 1.
