Out here in Wyoming, the alluvial and lacustrine deposits preserve some pretty nifty trace fossils. While boppin' around the fluvial strata in the basin (which is my focus), I ran across some pretty slick tracks, shown in the picture below.
These bird tracks have been attributed what was most-likely an extremely goofy looking Eocene bird, Presbyornis. I know, it might seem to be a little harsh to just summarily judge some poor extinct critter as silly lookin', but come on! Here's a life reconstruction of the goofy guy, (picture seized from here):
Presbyornis looks like a flamingo, and probably lived like a flamingo, but was actually a member of the Order Anseriformes, making it more closely related to a duck. Paleo-folks reckon it dabbled in the shallow, saline lakes in the western U.S., eating up brine shrimp and probably getting giggled at by all the other birds in the area.
