Camelotia
Camelotia (meaning "from Camelot") was a genus of sauropodomorph dinosaur from the Late Triassic of what is now England. Paleontologists are divided on which family it may belong to; in the past, Camelotia has generally been assigned to the prosauropods, but this group of primitive dinosaurs is in constant flux.
The type species, C. borealis, was first described by Galton in 1985. Dinosaurs formerly known as Avalonianus and Gresslyosaurus turned out to be Camelotia.
