The excellent preservation of these skeletal elements, combined with insights from other pelagornithid specimens, allows for a detailed reconstruction of P. Sandersi. In life, the feathered wings of this bird would have measured and estimated 6.06 to 7.38 meters(20-24feet) tip to tip-the largest wingspan of any birds
On record, living or extinct, and more than double the average wingspan of the largest modern flying bird species, the wandering albatross. Extrapolating from the circumference of the weight-bearing leg bones, P. Sandersi would have tipped the scales at somewhere between 21.9 and 40.1kg(48 to 88 pounds)-the weight of golden retriever. Although massive compared with modern fliers, the animal was dainty for its wing-span, thanks to its small body and ultralight weight skeleton.
