The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long
held to have evolved independently in each group, a reasonable assumption when it was …

Birds and mammals are key elements of modern ecosystems, and many biologists explain
their great success by their endothermy, or warm-bloodedness. New palaeontological …

The Triassic has long been recognized as a time during which marine and terrestrial
ecosystems modernized dramatically, and it seems to have been a two-step process. First …

Endothermy underpins the ecological dominance of mammals and birds in diverse
environmental settings 1, 2. However, it is unclear when this crucial feature emerged during …

The sedimentology and taphonomy of in-situ fossils from earliest Triassic strata (Induan) in
the southern Karoo Basin of South Africa is presented as evidence for episodes of drought …

Crocodilians grow slowly and have low metabolic rates similar to other living reptiles, but
palaeohistology indicates that they evolved from an ancestor with higher growth rates. 1, 2 …

The acquisition of the load-bearing dentary–squamosal jaw joint was a key step in
mammalian evolution,,,–. Although this innovation has received decades of study, questions …

As evolutionary biologists, we live in exciting and promising times. The material basis of our
science is growing at an unprecedented rate; fossils preserving structures we thought …

Abstract Triassic cynodonts from South America are key taxa in the investigation of the
emergence of mammalian characters. One of the most iconic species from the Carnian is …
