Lenisicaris is a Cambrian anomalocaridid radiodont, known from the Maotianshan Shales of China and the Kinzers Formation of Pennsylvania.

[1] In 1929, American paleontologist Charles E. Resser described a poorly preserved arthropod fossil from the Kinzers Formation.

[3] Numerous specimens have later been referred to this species, but the majority of them were subsequently assigned to different taxa of radiodonts.

[1] Lenisicaris is only known from frontal appendages, though these specimens have several distinguishing traits, most noticeably the lack of auxiliary spines.

[5] The type species L. lupata has smaller, triangular endites, closely resembling those of Anomalocaris.
