Re: Bird-like fossil footprints from the Late Triassic [repeat]



No morphological matches for these?

MELCHOR, RICARDO N., SILVINA DE VALAIS & JORGE F. GENISE,
2002. Bird-like fossil footprints from the Late Triassic.
Nature 417, 936 - 938 (2002).

Lots of early dinosaurs and -morphs and -forms diminished the medial and lateral toes. But the spread and retro digit are unknown until 55 million years later, at least to moi.

Any crazy hypotheses out there?
