       Brodavis was a genus of hesperornithiform that lived in both Asia and North America towards the end of the Cretaceous.‭ ‬Like relative genera,‭ ‬Brodavis would have dived below the water and used well developed feet to swim through the water after fish.‭ ‬What is perhaps most interesting though is that Brodavis was the first hesperornithiform bird that we knew of to have actually hunted in freshwater ecosystems rather than sea water.‭
       Because the bones of Brodavis do not have the same level of pachyostosis‭ (‬thickening of the bones‭) ‬as other hesperornithiformes,‭ ‬the genus has been speculated to have some volant‭ (‬flight‭) ‬abilities.‭ ‬This is a plausible argument given the wide distribution of the genus and obvious advantage of being able to reach new bodies of freshwater.‭ ‬However,‭ ‬it should also be remembered that fresh water does not have the same level of buoyancy as salt water.‭ ‬Therefore,‭ ‬if Brodavis only hunted in freshwater,‭ ‬their bones would not need to be as dense as their salt water relatives in order to sink their bodies below the surface of the water.
