Tappenosaurus ("Tappen's lizard") is an extinct genus of synapsids from the Middle Permian of Texas. American paleontologists Everett C. Olson and James Beerbower described the genus in 1953 based on three specimens that were uncovered from the San Angelo Formation.[1] It was named for Neil Tappen, who found the type specimen in 1951 as a member of the field party.
