Attenuated evolution of mammals through the Cenozoic
- Environmental Science, BiologyScience
- 2022
The rate of evolutionary change peaked around the time of the Cretaceous-Paleogene boundary and has general tapered off since then, whereas in some species such as rodents, morphological change appeared to be decoupled from taxonomic diversification.
Multiple paths to morphological diversification during the origin of amniotes.
- BiologyNature ecology & evolution
- 2021
Evidence for an early burst, comprising high rates of anatomical change that decelerated through time, giving way to a background of saturated morphological evolution is found, demonstrating the importance of variation in modes of phenotypic divergence during a major evolutionary radiation.
New tools suggest a middle Jurassic origin for mammalian endothermy
- BiologyBioEssays : news and reviews in molecular, cellular and developmental biology

We suggest that mammalian endothermy was established amongst Middle Jurassic crown mammals, through reviewing state‐of‐the‐art fossil and living mammal studies. This is considerably later than the…
Environmental signal in the evolutionary diversification of bird skeletons
- Biology, Environmental ScienceNature

Morphological diversification in living birds is analysed, with substantial variation in evolutionary modes among subgroups and skeletal parts found, along with an important role for environmental divergence in structuring the radiation of crown-group birds.
The geometry of synapsid skull disparity
- BiologyHistorical Biology
- 2022
It is found that synapsids changed their geometric rules of skull organisation; in the Permo-Trias, the orbit and the braincase changed concomitantly, as in the diapsids, hence being more ‘reptilian’.
Ecological selectivity and the evolution of mammalian substrate preference across the K–Pg boundary

Abstract The Cretaceous–Paleogene (K–Pg) mass extinction 66 million years ago was characterized by a worldwide ecological catastrophe and rapid species turnover. Large‐scale devastation of forested…
Shifts in food webs and niche stability shaped survivorship and extinction at the end-Cretaceous

It has long been debated why groups such as non-avian dinosaurs became extinct whereas mammals and other lineages survived the Cretaceous/Paleogene mass extinction 66 million years ago. We used…

Comparison of Hindlimb Muscle Architecture Properties in Small-Bodied, Generalist Mammals Suggests Similarity in Soft Tissue Anatomy
- BiologyJournal of Mammalian Evolution
- 2022
Hindlimb muscles of the gray short-tailed opossum are dissected and specialization for either large force production or longer active working ranges in proximal limb regions is found but neither specialization in more distal limb regions, suggesting either deep conservation of therian hindlimb muscle properties or a biomechanical constraint imposed by small body size.

Adaptive radiation of multituberculate mammals before the extinction of dinosaurs
- Environmental Science, GeographyNature
- 2012
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.

Therian mammals experience an ecomorphological radiation during the Late Cretaceous and selective extinction at the K–Pg boundary
- Environmental Science, GeographyProceedings of the Royal Society B: Biological Sciences

The conflicting diversity and disparity patterns suggest that earliest Palaeocene extinction survivors, especially eutherian dietary generalists, underwent rapid taxonomic diversification without considerable morphological diversification.
Mammal disparity decreases during the Cretaceous angiosperm radiation
- Geography, Environmental ScienceProceedings of the Royal Society B: Biological Sciences
- 2013
It is concluded that during the mid-Cretaceous, the period of rapid angiosperm radiation, mammals experienced both a decrease in morphological disparity and a functional shift in dietary morphology that were probably related to changing ecosystems.

The largest cladistic analysis of Paleocene placentals to date is presented, from a data matrix including 177 taxa (130 of which are Palaeogene) and 680 morphological characters, and supports an Atlantogenata–Boreoeutheria split at the root of crown Placentalia, the presence of phenacodontids as closest relatives of Perissodactyla, and the validity of Euungulata.

It is shown that Placentalia likely originated in the Late Cretaceous, but that most intraordinal diversification occurred during the earliest Palaeocene, supporting the view that an evolutionary radiation occurred as placental lineages invaded new ecological niches during the EarlyPalaeocene.
Ontogenetic niche shifts in dinosaurs influenced size, diversity and extinction in terrestrial vertebrates
- Environmental Science, BiologyBiology Letters
- 2012
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.
Patterns of mammalian jaw ecomorphological disparity during the Mesozoic/Cenozoic transition
- Environmental Science, GeographyProceedings of the Royal Society B
- 2019
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.
Phylogenetic evidence for a shift in the mode of mammalian body size evolution at the Cretaceous‐Palaeogene boundary
- Environmental Science, Geography
- 2013
This study uses a time‐calibrated phylogeny of living and fossil Mammaliaformes as a framework to test novel models of body size evolution derived from palaeontological theory, and finds that a model comprising an Ornstein–Uhlenbeck process until the K‐Pg event and a Brownian motion process from the Cenozoic onwards was the best supported model.
