Much of our view on Mesozoic dinosaur diversity is obscured by biases in the fossil record. In particular, spatiotemporal sampling heterogeneity affects identification timing and geographical location radiations, recognition latitudinal gradient, as well interpretation purported extinctions, faunal turnovers their drivers, including Early Jurassic Jenkyns Event across Jurassic/Cretaceous boundary. The current distribution means it impossible to robustly determine whether these 'events' were globally synchronous geologically instantaneous or spatiotemporally staggered. Accounting for also paramount reconciling notable differences results based sampling-standardized species richness versus reconstructions diversification rates, particularly with regards lead-up Cretaceous/Paleogene mass extinction. Incorporation a greater proportion stratigraphically well-resolved dinosaurs into analyses imperative must include substantial radiation birds. Given relative rarity temporally successive, well-sampled spatial windows, remains possible that rate showed little change after clade's initial until However, better understanding underlying sampling, combined holistic approach reconstructing diversification, an important step testing this hypothesis.

Abstract Global climate patterns fundamentally shape the distribution of species and ecosystems. For example, Bergmann’s rule predicts that homeothermic animals, including birds mammals, inhabiting cooler climates are generally larger than close relatives from warmer climates. The modern world, however, lacks comparative data needed to evaluate such macroecological rules rigorously. Here, we test for in Mesozoic dinosaurs mammaliaforms radiated within relatively temperate global regimes. We develop a phylogenetic model accounts biases fossil record allows variable evolutionary dispersal rates. Our analysis also includes new extreme high-latitude Late Cretaceous Arctic Prince Creek Formation. find no evidence or mammaliaforms, ancestors extant mammals.

We used Markov networks, ecological niche partitioning, Earth System models to reconstruct North American food webs simulate ecospace occupancy before after event. find a shift in latest Cretaceous dinosaur faunas, medium-sized species counterbalanced loss of megaherbivores, but niches were otherwise stable static, potentially contributing their demise. Smaller vertebrates, including mammals, followed consistent trajectory increasing trophic impact relaxation limits beginning continuing extinction. Mammals did not simply proliferate event; rather, earlier diversification might have helped them survive.
