Scientific Classification

Class:               Actinopterygii (Ray-finned Fish)

Order:              Labriformes

Family:             Labridae

Genus:             Pseudosphaerodon

Species:          antiquus (Casier 1966)

Pseudosphaerodon is a very unusual and rare fish from the London Clay with very few specimens known to have been found. It showcases rounded teeth within the jaws consistent with some modern Wrasse. There is some debate as to where this fish sits in terms of classification with some believing this is a Labridae while other researchers thinking it sits under Perciformes.

Distinguishing Characteristics:
  • Rounded teeth on the lateral margins of both upper and lower jaws (1)
