Schramidontus is a genus of crustaceans from the Late Devonian period found in Strud, Belgium, closely related to Angustidontus and classified as part of the order Angustidontida.
The generic name derives from Frederick Schram, who helped the scientific community in the field of the Palaeozoic malacostracans and the suffix -idontus in relation to the similarities between Schramidontus and Angustidontus.
Angustidontids are diagnosed as eucarids that possess carapaces and stalked eyes with "scale-like exopods" on the second antennae, an elongated pleion and a tail fan.
These features make the group distinct from most eumalacostracan crustaceans and they are classified as part of the Eucarida due to their carapace being fused to thoracic segments 1-7.
In these deposits fossil remains have been found of several animals such as tetrapods and a fauna of well-preserved freshwater crustaceans, including decapods, conchostracans, notostracans and anostracans.
