How Mammals Grew in Size Mammals diversified greatly after the end-Cretaceous extinction, which eliminated the dominant land animals (dinosaurs). Smith et al. (p. 1216) examined how the maximum size of mammals increased during their radiation in each continent. Overall, mammal size increased rapidly, then leveled off after about 25 million years. This pattern holds true on most of the continents—even though data are sparse for South America—and implies that mammals grew to fill available niches… Expand
The maximum rate of mammal evolution
TLDR
An exponential increase in maximum mammal body mass during the 35 million years following the Cretaceous–Paleogene extinction event is found and a basic asymmetry in macroevolution is indicated: very large decreases can happen at more than 10 times the rate of increases. Expand
Body size downgrading of mammals over the late Quaternary
TLDR
This work demonstrates that size-selective extinction was already under way in the oldest interval and occurred on all continents, within all trophic modes, and across all time intervals, and the degree of selectivity was unprecedented in 65 million years of mammalian evolution. Expand
Ontogenetic niche shifts in dinosaurs influenced size, diversity and extinction in terrestrial vertebrates
TLDR
A model is developed that quantifies the impact of size-specific interspecies competition on abundances of differently sized dinosaurs and mammals, taking into account the extended niche breadth realized during ontogeny among large oviparous species and predicts low diversity at intermediate size classes, consistent with observed diversity distributions of dinosaurs, and of Mesozoic land vertebrates in general.

The evolution of mammal body sizes: responses to Cenozoic climate change in North American mammals
TLDR
This model argues that the body sizes of Nearctic mammals were moulded by Cenozoic climate and vegetation changes, and reemphasizes the necessity of considering the evolutionary history and resultant form and function of mammalian morphotypes when attempting to understand contemporary mammalian body size distributions. Expand
diversity and extinction in terrestrial vertebrates Ontogenetic niche shifts in dinosaurs influenced size
TLDR
Dinosaurs have more complex ontogenetic lifehistories than similar-sized mammals, implying more extensive ecological niche shifts through their develop-ment, and their implications for body size distributions of the dominant terrestrialvertebrate groups of the Mesozoic and Cenozoic. Expand
Patterns of maximum body size evolution in Cenozoic land mammals: eco-evolutionary processes and abiotic forcing
TLDR
The temporal distribution of maximum size observed within individual orders globally and on separate continents is investigated and it is concluded that the macroevolutionary patterns observed are a result of the interplay between eco-evolutionARY processes and abiotic forcing. Expand
Body size evolution in palaeognath birds is consistent with Neogene cooling-linked gigantism
Abstract Palaeognathae is an extant clade of birds with body masses ranging over several orders of magnitude of kilograms, including the largest-yet described terrestrial avian species. Most studiesExpand
The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary
Abstract The transition of hominins to a largely meat-based diet ∼1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modernExpand
Patterns of mammalian jaw ecomorphological disparity during the Mesozoic/Cenozoic transition
TLDR
Total mammal disparity exceeded its Mesozoic maximum for the first time during the Eocene, when therian mammals began exploring previously unoccupied regions of function space, and probably reflects the duration of evolutionary recovery after the K/Pg mass extinction event. Expand
Adaptive radiation of multituberculate mammals before the extinction of dinosaurs
TLDR
It is shown that in arguably the most evolutionarily successful clade of Mesozoic mammals, the Multituberculata, an adaptive radiation began at least 20 million years before the extinction of non-avian dinosaurs and continued across the Cretaceous–Paleogene boundary. Expand

Dinosaurs, dragons, and dwarfs: The evolution of maximal body size
TLDR
The body mass of the top species was found to increase with increasing land area, with a slope similar to that of the relation between body mass and home range area, suggesting that maximum body size is determined by the number of home ranges that can fit into a given land area. Expand

TLDR
Paleofaunal data confirm that there were fewer mammalian species during the latest Cretaceous than during any interval of the Cenozoic, and that a massive diversification took place during the early Paleocene, immediately after a mass extinction. Expand
Cope's rule and the dynamics of body mass evolution in North American fossil mammals.
TLDR
Body mass estimates for 1534 North American fossil mammal species show that new species are on average 9.1% larger than older species in the same genera, which partially explains the unwavering lower size limit and the gradually expanding mid-sized gap. Expand
Large Mesozoic mammals fed on young dinosaurs
TLDR
A new species of triconodont mammal is reported, represented by a skeleton with most of the skull and postcranium preserved in articulation and stomach contents associated with a skeleton of R. robustus reveal remains of a juvenile Psittacosaurus, a ceratopsian dinosaur. Expand

The observed shifts in maximum body size approximate the rate of diversification per unit of time to the power of about 0.5. Expand
