I've been away for a bit, but am interested in trying to get back into the swing of things here so please bear with me. This is a paper from late last year that I haven't mentioned before.
Drumheller, S. K., M. R. Stocker, and S. J. Nesbitt. 2014. Direct evidence of trophic interactions among apex predators in the Late Triassic of western North America. Naturwissenschaften 101:975-987. DOI 10.1007/s00114-014-1238-3
Rather than get into the details here I'll send you to this podcast which does a great job featuring the significance of this study.
It just might happen! Or not.
