The '''joanusauroidae''' or '''joanusaurids''' (meaning "Joanus' lizards") was a superfamily or clade of {{wpl|Theropod|theropod}} {{wpl|Dinosaur|dinosaurs}}. The joanusaurids are thought to have been among the {{wpl|Apex predator|apex predators}} that were active on the supercontinent [[Sarpolevantia]] from the {{wpl|Middle Jurassic}} to the {{wpl|Late Cretaceous}} periods {{circa}} 175-65 million years ago. Paleontologists agree that ''[[Projoanusaurus]]'' (literally "before ''[[Joanusaurus]]''") is the earliest known joanusauroid, though some suspect earlier more basal joanusauroids may have existed but are yet to be discovered from the sparse {{wpl|Middle Jurassic}} sediments of eastern [[Sarpedon]] and southern [[Levantia]]. True joanusaurids (joanusauridae) split off from the clade [[Sarponychid|sarponychidae]] at some point during the {{wpl|Late Jurassic}}, at which time the two families diversified immensely. The {{wpl|Most recent common ancestor|most recent common ancestor}} of joanusauridae and [[Sarponychid|sarponychidae]] is thought to have been ''[[Magnalophosaurus]]''. The last known living member of the joanusaurids was ''[[Levaretyrannus]]'' whose fossilized remains have been found in central and western [[Levantia]] in sediments dating to the {{wpl|Cretaceous–Paleogene extinction event}} {{circa}} 65.5 million years ago, during which more than 75% of all species died out including all non-avian dinosaurs. | The '''joanusauroidae''' or '''joanusaurids''' (meaning "Joanus' lizards") was a superfamily or clade of {{wpl|Theropod|theropod}} {{wpl|Dinosaur|dinosaurs}}.
