The Carboniferous Period

The period began 358.9 million years ago and ended 298.9 million years ago

The Majority of Carboniferous spiders are actually in the family Solifugae which are arachnids but not spiders, the modern descendants of this group are the sun spiders.

In France we’ve found an early sister group to modern day spiders that lacks the silk producing organs of modern day spiders.

The greatest characteristic of this era is the giant bugs! There were extra big dragonflies, Mayflies, Cockroaches, Grasshoppers, Crickets, Terrestrial Scorpions and Spiders!

Named Carboniferous because of the large underground coal deposits from this era, formed from prehistoric organisms, these deposits are typically found in areas that were tropical, denoted as coal swamps.

Temperature wise the patterns of the period were very similar to how things are how now, basic temperature determined by latitude

Following Devonian extinctions the period contained a multitude of sea organisms that were distinctly different from the previous time periods. Coral varieties were very limited so reefs from this period were notably flimsy.

Cephalopods experienced a boom during this time period with many of the ones that we know today (nautilus, squid and octopi) starting to take shape.
