only by fossils of the Mesozoic, the earliest mammals are from the Late Triassic, a bit over …

Mammals are the dominant large animals of today, occurring in virtually every environment.
This book is an account of the remarkable 320 million year long fossil record that documents …

Advances in dating and systematics have prompted a revision of monotreme evolution to
refine the timing of adaptative trends affecting body size and craniodental morphology. The …

The first fossil chordates are found in deposits from the Cambrian period (545–490 million
years ago), but their earliest record is exceptionally sporadic and is often controversial …

We propose a phylogeny of all major groups of Mesozoic mammals based on phylogenetic
analyses of 46 taxa and 275 osteological and dental characters, using parsimony methods …

As the first four-legged vertebrates, called tetrapods, crept up along the shores of ancient
primordial seas, feeding was among the most paramount of their concerns. Looking back …

The evolution of tribosphenic molars is a key innovation in the history of Mammalia.
Tribospheny allows for both shearing and grinding occlusal functions. Marsupials and …

Radiometric U–Pb ages are presented for the Riversleigh World Heritage fossil mammal site
