It is suggested that Cordylodus andresi can be a marker of the Cambrian Stage 10.

Distribution

Fossils of Cordylodus have been found in Argentina, Australia, Canada (Quebec), China, Colombia (Tarqui, Huila),[2] Kazakhstan, Malaysia, Mexico, Norway, the Russian Federation, Sweden, and the United States, in the states of Alaska, Minnesota, Nevada, New York, Oklahoma (Bromide Formation), Vermont and Wyoming.[3]

C. horridus has been recovered from the Blakely Sandstone and C. angulatus from the Collier Shale, Ordovician geologic formations in the Ouachita Mountains of Arkansas and Oklahoma.

gollark: This was apparently inspired by the Scottish system.
gollark: In US universities you apparently study for four years and do a wide range of sub-courses and whatever, in English ones you typically do three and only really have a few optional modules somewhat related to your chøsen field.
gollark: UK universities apparently do significantly more specialized courses than US ones.
gollark: Excellent, orbital mind control lasers working as designed.
gollark: In the UK I imagine that if you wanted to do maths at a cool™ university you would have to have decent grades at it, at least, and have some good explanation for why you want to study it.
