Cowielepis ritchiei[1]

Cowielepis is an extinct genus of jawless fish in the class Anaspida. It is from the Cowie Harbour fish bed (Cowie Formation) of Stonehaven, Scotland, which age was originally considered as the Silurian (Wenlock to Ludlow), one study reassigned to Early Devonian (Lochkovian),[2] and 2023 study suggested Wenlock age again.[3]

Restoration of Cowielepis ritchiei

Habits

It was possibly a nectonic filter, of active locomotion, due to its physiognomy.

Distribution

Lochkovian of United Kingdom (Scotland).[4]
