A group of investigators managed to discover the existence of a molecular complex in fossils dating back to the Paleozoic period, which spanned between 542 and 251 million years ago.

According to fossil records dating back as far as 500 million years ago, the earliest arthropods to venture on land also looked for discarded shells to use for protection. The lineage is far older than that of the hermit crab, originating some 200 million years ago, and that was thus far the oldest known to exhibit s... |

The latest fossils found prove that the number of crawling creatures that crowded the Cambrian shores was larger than previously believed. And that they were not alone. About 500 million years ago, during the Cambrian age, all of Earth's life was concentrated in the planetary oceans. Paleontologists assume ... |
