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. Zur Fauna des lithographi

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 bl

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.

Geocoma carinata (v. Münster in Goldfuss, 1833)
oilshale posted a fossil in Starfish and Brittlestars
Brittle stars are rather rare in the lithographic limestone of Solnhofen, but are quite common in Zandt. -
