 Most common, however, were straight-jawed, needle-toothed forms, some of the most notable being "Ctenochasma" and "Gnathosaurus"; these possibly occupied an ecological niche akin to that of modern spoonbills, their teeth forming spatula-like jaw profile extensions, allowing them a larger surface area to catch individual small prey.Most ctenochasmatoids have wing proportions akin to those of modern shorebirds and ducks, and probably possessed a similar frantic, powerful flight style.The exception is "Ctenochasma", which appears to have had longer wings and was probably more comparable to modern skuas.
