Amniotes are thought to have diverged from amphibians at the dawn of the Carboniferous period, about 355 million years ago. Mammals would diverge from reptiles and birds only 30 million years later.

Here’s what you’ll learn when you read this story: The common ancestor of all tetrapods (including humans) was previously thought to have emerged at the dawn of the Carboniferous 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.

Most scientists agree amphibians and amniotes separated at the start of the Carboniferous period, about 355 million years ago. Later in the period, the amniote lineage split further into the ancestors ...

The latest findings suggest that amniotes also existed in the early Carboniferous period, around 355 million years ago.
