A 183-million-year-old plesiosaur fossil unveils rare skin details, reshaping our understanding of ancient marine life.

The fossils of ancient salamander-like creatures in Scotland are among the most well-preserved examples of early stem tetrapods -- some of the first animals to make the transition from water to land.

However, the lack of fossils capturing the transition from terrestrial mammal to volant chiropteran has obscured much of our understanding of bat evolution. Over the last 20 years, the emergence of ...

Mosura fentoni, as the species is known, belongs to a group called radiodonts, an early offshoot of the arthropod evolutionary tree, according to a new study published Tuesday in the journal Royal ...

Australian tree frogs today make up over one third of all known frog ... Unravelling the deep-time changes in the diversity and evolution of the ancestors of today's living animals can provide ...

In the Early Eocene epoch, 55 million years ago, Australia’s tree frogs were hopping across ... Unravelling the deep-time changes in the diversity and evolution of the ancestors of today ...

Newly discovered evidence of Australia's earliest species of tree frog challenges what we know about when Australian and South American frogs parted ways on the evolutionary tree. Previously, ...

Those feathers also place the species more accurately on the evolutionary tree among winged dinosaurs as well as a predecessor to contemporary birds, which also have tertials. “Archaeopteryx isn’t the ...

Called Kentia Palms, Professor Savolainen is part of a study team examining how it is that these palms found enough evolutionary elbow room on the small island to speciate into unique trees.

In 2015, a genetic study in the journal Nature suggested that the hoatzin is the last surviving member of a bird line that branched off the evolutionary tree in its own direction 64 million years ...
