Acastoidea

Acastoidea

Acastoidea is a superfamily of trilobites from the order Phacopida, suborder Phacopina. This superfamily is divided into two families, Acastidae and Calmoniidae. This superfamily is distinguishable from Phacopidae in that their eyes are closer to their glabellar and that their glabellar has lobes, unlike the genera in Phacopidae.
