Devonian’s core strategy is to develop prescription drugs for the treatment of inflammatory autoimmune diseases including but not limited to ulcerative colitis and atopic dermatitis.

Fossil tracks from Australia reveal reptiles appeared 40 million years earlier than thought. The origin of reptiles on Earth may be up to 40 million years earlier than previously believed, based on ...

If amniotes had already evolved by the earliest Carboniferous, as our fossil shows, the last common ancestor of amniotes and amphibians must lie much further back in time, in the Devonian period.

If amniotes had already evolved by the earliest Carboniferous, as our fossil shows, the last common ancestor of amniotes and amphibians has to lie much further back in time, in the Devonian period.

The first feet on land Tetrapods originated a long time ago in the Devonian period, when strange lobe-finned fishes began to haul themselves out of the water, probably around 390 million years ago.

It’s quite possible. Only more fieldwork, bringing to light new discoveries of Devonian and Carboniferous fossils from the old Gondwana continents, might one day answer that question. Top image: ...

The Devonian period was seen as inhabited by more primitive fish-like tetrapods and transitional 'fishapods' such as Tiktaalik. A sandstone slab from the earliest Carboniferous of Australia, ...

But if the ancestors of reptiles existed during the early Carboniferous, their split from amphibians must have occurred even earlier, says Long.
