Description
Original diagnose after Underwood & Claeson (2019) p. 346 [25550]: Batoid like Spathobatis (Thiollière, 1854) and Belemnobatis (Thiollière, 1854) characterised by “guitarfish” like form. Kimmer- obatis possesses a depressed body, caudal region large in proportion to disk, tail distinct from disk, fins aplesodic; hyomandibula with broad medial articulation with chondrocranium; unsegmented propterygia; no pectoral radials that articulate directly with scapulocoracoid between mesopterygium and metapterygium; synarcual short with vertebral centra nearly reaching neuro- cranium. Unlike Spathobatis, but like Belemnobatis, in having pectoral fins not extending to overlap pelvic fins and lacking enlarged placoid scales. Unlike Spathobatis and Belemnobatis in having subtriangular rostrum that fails to reach end of snout; no rostral appendix; incipient lingual uvula on teeth; post-pelvic process; neural spines of caudal region longer than centra; no fin spines; rugose axial cartilage of clasper.
