Dual purpose image, partly a commission and partly intended for a future issue of Prehistoric Times that has an article about Andrewsarchus. On an Eocene beach an Andrewsarchus squares off with a type of prehistoric bird over a very dead shark. The bird isn't a particular species, although it's roughly based on a species called Osteodontornis that was found a little bit later than this. But the books say this family of bird existed during the Eocene, so there it is. There isn't a ton of reference on Eocene birdlife. Unfortunately I couldn't really show any scale here, but the Andrewsarchus is about 6 feet at the shoulder. And yes, Osteodonthornids were very large, considerably bigger than any exant flying bird.
