Diagnosis from Haug & Haug 2021, p. 11: "Stomatopod of moderate size. Body subcylindrical. Posterior feeding apparatus (maxillipeds 2–5) with first pair of raptorial appendages large, second pair of medium size, posterior two pairs being small. No dorsal surface ornamentation on shield or tergites. Pleopods with multi-annulated (outer ?) ramus. Uropods with lanceolate to paddle-shaped endo- and exopods. Endopods of uropods with serration along the median margin. Exopods of uropods with movable teeth along the lateral margin." References: C. Giebel. 1857.

Comments Amblysemius was clearly a predator as evidenced by its mouth full of sharp teeth. It was a notable fast swimmer. Together with its only sister genus Caturus, Amblysemius was a member of the extinct Halecomorpha family Caturidae. It appears that the halecomorph Liodesmus, known from Solnhofen only, is related to the Caturids, rather than the amiiforms, as has been usually surmised. Once a diverse major group of bony fishes, the Halecomorpha have only one surviving member, the bowfin (Amia calva) of eastern North America. Living bowfins are remarkably hardy since they have a swim bladder that opens into their esophagus so they can gulp air, and hence survive in water with low oxygen. Amblysemius was a primitive species of fish that thrived during the Jurassic Period but went extinct by the Lower Cretaceous Period. Amblysemius possessed ganoid scales that are more cycloid in nature and as a member of the holosteans a bony skeleton with a partially ossified vertebral column. The Caturidae are represented in the Solnhofen Formation by at least four species: Caturus furcatus Agassiz 1834 and Caturus giganteus Wagner, 1851. Caturus pachyurus Agassiz, 1833 and Caturus bellicianus Thiollière 1852 from Solnhofen, Germany and Cerin, France were transferred to the revived sister genus Amblysemius (now Amblysemius pachyurus and Amblysemius bellicianus). Compared to Caturus, Amblysemius is characterized by its more slender body outline, the bigger and more deeply forked caudal fin being heterocerc with the upper lobe clearly longer than the lower one and the strong dentition. Amblysemius has considerably smaller scales compared to Caturus. Maximum length is around 50cm; this specimen has only 20cm or 8".

Taxonomy from GBIF.org. Diagnosis (from Arratia 1997): "Small, elongated teleost with a known maximum length of 65 mm. Head length 23–27% of standard length. Ethmoidal region about 24% of head length. With middle pit-line groove running onto pterotic. Two supraorbital bones, the first one expanded anteroventrally. Preopercular limbs form an angle of 90°. Quadrate-mandibular articulation placed below center of orbit. Dorsal fin origin anterior to pelvic fin origin. Origin of dorsal fin at 54–63% of standard length. Origin of anal fin at 84–88 % of standard length. With 45 or 46 vertebrae. Pectoral fin rays 15–19, pelvic fin rays 10–11, dorsal fin rays 15–16, anal fin rays 9. Complex epipleural bones bearing two or three thin projections about midlength of vertebral column."
