Weathering the tough times: Fossil evidence of 'hibernation-like' state in 250-million-year-old Antarctic animal
Weathering the tough times: Fossil evidence of ’hibernation-like’ state in 250-million-year-old Antarctic animal
Hibernation is a familiar feature on Earth today. Many animals - especially those that live close to or within polar regions - hibernate to get through the tough winter months when food is scarce, temperatures drop and days are dark.

Tracking Australia's gigantic carnivorous dinosaurs
Tracking Australia’s gigantic carnivorous dinosaurs
North America had the T. rex , South America had the Giganotosaurus and Africa the Spinosaurus - now evidence shows Australia had gigantic predatory dinosaurs. The discovery came in University of Queensland research, led by palaeontologist Dr Anthony Romilio , which analysed southern Queensland dinosaur footprint fossils dated to the latter part of the Jurassic Period, between 165 and 151 million-year-ago.

Our image of dinosaurs was shaped by Victorian popularity contests
Our knowledge of dinosaurs has expanded greatly since the public first became aware of their existence, but the history of these animals encompasses more than just the fossils themselves, writes Richard Fallon (UCL Science & Technology Studies).

Mammals and their relatives thrived, diversified during so-called ’Age of Dinosaurs,’ researchers show
Paleontologists are trying to dispel a myth about what life was like when dinosaurs roamed the Earth. The false narrative has wormed its way into books, lectures and even scientific papers about this long-ago era. The myth's focus isn't on dinosaurs. Its main characters are ancient mammals and their relatives, which together are known as mammaliaforms.

Shakes up sloth family tree
One of the world's leading economists explains why our communities could hold the answer to many of society's problems. Sloths once roamed the Americas, ranging from tiny, cat-sized animals that lived in trees all the way up to massive ground sloths that may have weighed up to six tons. The only species we know and love today, however, are the two-toed and three-toed sloths-but paleontologists have been arguing how to classify them, and their ancestors, for decades.

Bristol undergraduate reconstructs the skulls of two species of ancient reptile
Using two partially fragmented fossil skulls, a student at the University of Bristol has digitally reconstructed, in three-dimensions, the skulls of two species of ancient reptile that lived in the Late Triassic, one of which had been previously known only from its jaws.

Innovative online Birmingham courses produce first graduates
A new species of ancient reptile has been described by scientists at the University of Birmingham, filling a critical gap in the fossil record of dinosaur cousins and suggesting that some features thought to characterise dinosaurs evolved much earlier than previously thought. Described in a paper published today in Nature, the carnivorous reptile, Teleocrater rhadinus, was approximately 7-10 feet in length, had a long neck and tail, and walked on four crocodile-like legs.

Origin of the turtle shell lies in digging
Origin of the turtle shell lies in digging
In today's turtles the shell has a key protective function. The animals can withdraw into it and protect themselves against predators. No other group of vertebrates has modified its physique to such an extent to develop an impenetrable protective structure. "For a long time, paleontologists and developmental biologists puzzled over the origin of the tortoise shell," explains Torsten Scheyer, a paleontologist at the University of Zurich.
