Alvarezsaurids were mostly small-bodied theropods that paleontologists originally misinterpreted as early flightless birds, only to later recognize them as an ant-eating lineage of non-avian dinosaurs.

There have probably been many people of Newton's caliber who died before they had a chance to contribute meaningfully to scientific progress.
