^Sounds like that whole thing phenomenon about young mega theropods have an oppressive effect on the mid-size carnivore niche.
I remember reading some article suggesting that dinosaurs were on the decline before the asteroid impact, based on the fact that dinosaur diversity wasn't all that high, but it seems more likely that the species that existed seemed to be doing really well to the deteriment of other animals.

New vertebrate fauna from the Lower Cretaceous Holly Creek Formation. peerj.com/articles/12242/^Sounds like that whole thing phenomenon about young mega theropods have an oppressive effect on the mid-size carnivore niche. I remember reading some article suggesting that dinosaurs were on the decline before the asteroid impact, based on the fact that dinosaur diversity wasn't all that high, but it seems more likely that the species that existed seemed to be doing really well to the deteriment of other animals. There have been studies which found the whole "dinosaur decline" thing to be unsupported due to sampling biases anyway. The fact that some megatheropods (at the very least tyrannosaurids) had juveniles occupying the mid-sized carnivore niches in their ecosystems is probably also worth considering. There may have been less species, but the species that were there were doing very well.

Evolution of synapsid tusks. Not all dicynodonts had true tusks (which are ever-growing), but others evolved them convergently. It seems that the evolution of true tusks requires reduced tooth replacement and permanent soft tissue attachment. royalsocietypublishing.org/doi/10.1098/rspb.2021.1670

Proposed revision on Chibanian hominin taxa. It favors introducing a new species ( H. bodoensis), abandoning H. heidelbergensis and H. rhodesiensis, the western Europe heidelbergensis fossils being reassigned as Neanderthals, and Chibanian Chinese fossils likely being a separate lineage. onlinelibrary.wiley.com/doi/10.1002/evan.21929
