Do you think its possible that nanotyrannus and tyrannosaurus could've shared a similar relationship to lions and hyenas where they would hunt at different hours to avoid competition? (Lions and hyenas hunt the same prey, but lions hunt at night whereas hyenas hunt at day.)

Big news today impacting the ongoing controversy if large theropods were lipped.

We tested this hypothesis using a multiproxy approach. https://www.science.org/doi/10.1126/science.abo7877 Mark Witton blog http://markwitton-com.blogspot.com/2023/03/new-paper-fresh-evidence-and-novel.html
