Scientific NameCorydoras revelatus  Cockerell, 1936
Common NameFossil Cory
PronunciationKory DOOR ass
EtymologyCory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. 
Hop to next section Species Information
IdentificationCorydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

This is the only known fossil species of Corydoras.
SexingFemales grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
General RemarksIt is estimated that this specimen is around 58 million years old.
