The token non-mammal in this presentation, Zysquy zoia is a small sphenodont, rather similar to our tuatara. Sphenodonts were common in South America during the Cretaceous and even endured into the Paleocene in our timeline, but quickly became extinct, perhaps due to climatic changes at the PETM. Here though, they're only walking the first steps; in both timelines, squamates were severely decimated by the KT event, in some cases taking up to ten million years to recover. In our timeline lizards bounced back, but not here; by mere chance, sphenodonts and allocaudate amphibians beat them to the punch. If Potentioperadectes vastata is a pathetic little waste of potential, Zysquy zoia is an era about to begin.
