Taxacom: Triassic 'bird' tracks

[John Grehan]

Just posting this for anyone interested. Saw a brief news item on the web
about a new paper on some very bird- like fossil tracks. Unfortunately,
however bird-like, apparently no way to know if they were 'birds' in the
modern sense or not.  Attributed to authors: ?That these tracks of southern
Africa, dating to the Late Triassic, so strongly resemble Cenozoic and
modern bird tracks substantiates the converging pedal morphology of Late
Mesozoic archosaurs and firmly shows that the origin of bird-like foot
morphology is at least ~210 million years old.?
