Are both fish on this plate Asialepidotus shingyiensis?  The fossil is from Xingyi of Guizhou, China.

I don't know swat about fish identification, but it looks like the smaller one has a different scale type/configuration than the larger.

I agree, the scales are different relative shapes and sizes (bigger and more elongated on the smaller one) and the configuration is different too.

Without seeing the head bones of the fish, I don't trust myself with a determination.  Typical for Asialepidotus are large scales next to the anal fin - I don't see them here. There is a recent redescription by GUANG-HUI XU and XIN-YING MA:

"Redescription and phylogenetic reassessment of Asialepidotus shingyiensis (Holostei, Halecomorphi) from the Middle Triassic Ladinian of China"

Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).
