Earliest North American Bird

PR Newswire is reporting on the discovery of the earliest fossilized bird in North America. The story notes:

The new shoreline-inhabiting species bridges a gap in time and space between older enantiornithine birds found in Europe and Asia, and younger species from North and South America. Scientists had suspected these kinds of birds should have been in North America at the time, but direct evidence of their presence had been lacking until now.

More pieces of the puzzle.
