Shucaris (/ʃuːˈkɑːrɪs/ shoo-KAR-iss; meaning "Shu's shrimp") is a genus of radiodont of uncertain taxonomic placement from the Lower Cambrian Maotianshan Shales in Yunnan, South China.

The paratypes, JS-1950 and JS-0658, comprise a nearly complete body specimen, and one partial disarticulated assemblage of a frontal appendage, gnathobase-like structures, an oral cone, portions of the head sclerites, and a flap associated with setal blades, respectively.

[1] The appendage morphology of Shucaris is unlike any other radiodont in many respects, which makes taxonomic placement difficult.

The specific name, ankylosskelos, derives from the Greek words for 'curved' and 'leg' respectively, alluding to the curved frontal appendage.

[1] In previous studies, Shucaris was referred to as "Radiodont C" and has been recovered as an amplectobeluid[2] and a basal anomalocaridid.

Wu et al. (2024) recovered Shucaris as a radiodont of uncertain relation—often as a member of the Anomalocarididae—in their phylogenetic analyses.

Despite this however, Wu et al., (2024) discuss novel features Shucaris possesses such as "more podomeres in the claw region than all amplectobeluids and most anomalocaridids", leading them to recover Shucaris as "the most basal taxon within Anomalocarididae or a sister taxon to the clade comprising amplectobeluids and anomalocaridids".

[1] Shucaris had an abnormally small oral cone, suggesting that it likely chewed up prey with its gnathobase-like structures and then swallowed it.
