"The discovery of this new species, which we call Machaeracanthus goujeti and belongs to the Acanthodii group -of which very little is known-, expands our knowledge of the biodiversity that existed on the peninsula 480 million years ago, when the modern-day region of Teruel was covered by the sea," Hector Botella, professor in the palaeontology unit in the University of Valencia and the study's lead author, explained to SINC.

Some other fossil fishes also have a nodular ultrasculpture on their scales but it differs strongly in measurements (the nodes being very fine: 1-2 [micro]m in Acanthodii, see Beznosov 2001; 2.75-9.07 [micro]m in Actinopterygii, see Gayet & Meunier 1986).

The nodes are much finer (1-2 [micro]m) in Acanthodii from the Upper Devonian of Timan (Beznosov 2001) and 1.7-4.7 [micro]m in an acanthodian from Belgium (Derycke & Chancogne-Weber 1995).
