A new fossil amniote from the Fossil Forest of Chemnitz (Sakmarian-Artinskian transition,
Germany) is described as Ascendonanus nestleri gen. et sp. nov., based on five articulated …

Amniotes include mammals, reptiles and birds, representing 75% of extant vertebrate
species on land. They originated around 318 million years ago in the early Late …

Sensory perception is of crucial importance for animals to interact with their biotic and abiotic
environment. In amniotes, the clade including modern mammals (Synapsida), modern …

The largest published phylogenetic analysis of early limbed vertebrates (Ruta M, Coates MI.
2007. Journal of Systematic Palaeontology 5: 69–122) recovered, for example …

Mammals are arguably the most conspicuous tetrapods in the modern biota. Although there
are fewer extant mammal species (~ 5,500) than birds (~ 10,000) or squamates (~ 10,000) …

A fundamental concept in evolutionary biology is that life tends to become more complex
through geologic time, but empirical examples of this phenomenon are controversial. One …

Abstract The group of Permo-Carboniferous tetrapods known as Recumbirostra have
recently been hypothesized to represent the earliest radiation of fossorial reptiles. Therefore …

The acquisition of mammalian endothermy is poorly constrained both phylogenetically and
temporally. Here, we inferred the resting metabolic rates (RMRs) and the thermometabolic …

The origin of amniotes 320 million years ago signaled independence from water in
vertebrates and was closely followed by divergences within the mammal and reptile stem …

Abstract 'Microsaurs' are traditionally considered to be lepospondyl non‐amniotes, but
recent analyses have recovered a subset of 'microsaurs', the fossorially adapted …
