Oecotraustes is an extinct cephalopod genus included in the ammonid family Oppeliidae and named by Waagen[who?] in 1869. The genus lived during the Middle Jurassic.[1]


The shell of Oecotraustes is evolute, the outer whorl only moderately embracing the inner whorls, laterally compressed whorl height greater than width. Outer flanks and venter ribbed, ribs sinuous.[citation needed]


Fossils of Oecotraustes species have been found in Jurassic sediments of Germany, India, Madagascar, Spain, and the United States.[2]
