Calcarichelys ('spur turtle' or 'thorn turtle') is an extinct genus of protostegid turtle from the Late Cretaceous of the Selma Formation in Alabama, and possibly from Angola. It contains only one species, C. gemma. The species epithet "gemma" refers to the nickname "The Gem" given to the holotype by collector C. M. Barber due to it's preservation quality.
