amniotes

It may have been one of the very first true amniotes.

Both groups have evolved for over 300 million years from the early amniotes.

The amniotes gave rise to two groups both of which became dominant at different times.

This let amniotes move into environments that had less water.

My main efforts have been directed at structures in a wide range of amniotes.

Early amniotes had no openings in the skull behind the eyes.

Some scientists argue that humans dream for the same reason other amniotes do.

Archaeothyris and the other early amniotes lived on the forest floor.

Most scientists place them among the Reptilomorpha, as a sister group to the first amniotes.

Casineria was at or very near the origin of the amniotes.

In the amniotes, the cerebrum becomes increasingly large and complex.

The synapsids are the other group which evolved from amniotes.

The embryos of amniotes are either laid as eggs or develop in the female.

Once the amniotes were truly land animals, there followed a huge adaptive radiation.

The first amniotes, such as Casineria, looked like small lizards.

They were the amniotes, whose key innovation was the cleidoic egg.

It is present in most amniotes, and also in lungfish.

Synapsids are one of the two major groups of amniotes.

This was a key evolutionary 'invention', which allowed the amniotes to invade the land.

These traits shows it was closely related to amniotes.

Sometime in the middle or lower Carboniferous, the amniotes split into two lines.

Like many other terrestrial early amniotes, it probably had the diet of insects and smaller animals.

The Diadectomorphan families are generally considered to be the closest known relatives of modern amniotes.

Diadectes has been classified as belonging to the sister group of the amniotes.

The first amniotes are known from the early part of the Late Carboniferous.
