The
Fossil record
In prehistoric times, the loons had a more southerly distribution than today, and their fossils have been found in places such as California, Florida and Italy. The conflicting molecular data regarding their relationships is not much resolved by the fossil record; though they seem to have originated at the end of the Late Cretaceous like their presumed relatives, modern loons are only known with certainty since the Eocene. By that time almost all modern bird orders are at least strongly suspected to have existed – if not known from unequivocally identified specimens – anyway.[5]
The oldest known stem-gaviiform is Nasidytes from the Early Eocene aged London Clay of England, dating to around 55 million years ago.[7]
Some older fossils are sometimes assigned to the Gaviiformes. From the
