PloS one.PLoS One.2014 Jul 23;9(7):e103613. doi: 10.1371/journal.pone.0103613. eCollection 2014.
The skeletal record of tyrannosaurids is well-documented, whereas their footprint record is surprisingly sparse. There are only a few isolated footprints attributed to tyrannosaurids and, hitherto, no reported trackways. We report the world's first trackways attributable to tyrannosaurids, and descr
