Early Triassic marine vertebrate apex predators during the Griesbachian to Smithian interval (left) and the Spathian to Anisian interval (right). Predators not exactly to scale; see text and Tables S1–S2 for details on body size and stratigraphic occurrence. Marine vertebrate apex predators: 1, Wantzosaurus (trematosaurid ‘amphibian’); 2, Fadenia (eugeneodontiform chondrichthyan); 3, Saurichthys (actinopterygian ambush predator); 4, Rebellatrix (fork-tailed actinistian); 5, Hovasaurus (‘younginiform’ diapsid reptile); 6, Birgeria (fast-swimming predatory actinopterygian); 7, Aphaneramma (trematosaurid ‘amphibian’); 8, Bobasatrania (durophagous actinopterygian); 9, hybodontoid chondrichthyan with durophagous (e.g. Acrodus, Palaeobates) or tearing-type dentition (e.g. Hybodus); 10, e.g., Mylacanthus (durophagous actinistian); 11, Tanystropheus (protorosaurian reptile); 12, Corosaurus (sauropterygian reptile); 13, e.g., Ticinepomis (actinistian); 14, Mixosaurus (small ichthyosaur); 15, large cymbospondylid/shastasaurid ichthyosaur; 16, neoselachian chondrichthyan; 17, Omphalosaurus skeleton (possible durophagous ichthyosaur); 18, Placodus (durophagous sauropterygian reptile). © Printed under a CC BY license, with permission from Nadine Bösch and Beat Scheffold, original copyright [2013]. · CC BY 2.5 · Wikimedia
