Reconstruction of the arrangement of the continents during the Palaeozoic period deduced from palaeomagnetic data is virtually identical to the traditional geologically based reconstruction.

The presence of lung-books in fossil Arachnids is thus of importance in any phylo-genetic studies on the group. Petrunkeviteh 1–3 has reviewed the known Palæozoic and Mesozoic fossils and shown ...

This is a synapomorphy for the crown group of the Echinoidea, and is also true for all post-Palaeozoic echinoids, bar one, Tiarechinus. By contrast almost all Palaeozoic echinoids have a test which ...

The closest sister group to the echinoids are the holothurians and the two groups must have diverged from starfishes and ophiuroids between 500 and 450 million years ago. Echinoids remained only a ...

Paleontologists recently discovered a new extinct coelacanth species that highlights the role that Earth’s plate tectonics plays in evolution. Also called Latimeria, coelacanths are a deep-sea fish ...
