Codazziceras is an early Late Cretaceous ammonite from the Late Cretaceous of Colombia, distinguished from Lyelliceras (Lyelliceratidae) from which it is based and added to the Euomphaloceratinae (Acanthoceratidae).

[2][3] The genus is named after Italian-Colombian geographer Agustín Codazzi.

The shell is rather evolute, ornamented with ribs and clavate tubercles.

Ribs are fairly strong on the flanks but weaken as they cross the venter.

Whorl section is compressed, moderately embracing, flanks convex, venter moderately flattened with three rows of tubercles that tend to be elongate in the direction of coiling.
