[citation needed], A piece of a carpometacarpus supposedly from Oligocene rocks near Lusk, Wyoming, was described as Gaviella pusilla, but this handbone also shows some similarities to the plotopterids, flightless wing-propelled diving birds, and if these are apomorphic would make an unconvincing member of the Gaviidae (though it still could be a small-winged gaviiform in a yet-undescribed family "Gaviellidae"[45]): while the carpometacarpus in Gavia is somewhat convergent to that of wing-propelled diving birds, enabling the wings to be used as rudders for quick underwater turns, Colymboides still had an unspecialized plesiomorphic hand. The gastroliths may also be involved in stomach cleaning as an aid to regurgitation of indigestible food parts.
