Continents:
* Pangaea: The supercontinent Pangaea was forming, bringing together most of Earth's landmasses. This massive landmass stretched from pole to pole, with vast interior areas experiencing extreme temperatures.
* Large Swamps and Wetlands: The interior of Pangaea was largely covered in extensive swamps and wetlands. This was due to the warm, humid climate and the abundance of water from the merging of continents.
* Extensive Forests: These swamps and wetlands were dominated by vast forests of giant ferns, horsetails, and lycopods. These plants thrived in the warm, humid environment and created the conditions that eventually led to the formation of vast coal deposits.
* Mountains: Some mountain ranges were present, formed by the collision of continents that created Pangaea. These mountains likely influenced weather patterns and created diverse microclimates.
Climate:
* Warm and Humid: The Carboniferous climate was generally warm and humid, with temperatures averaging around 20°C (68°F).
* Seasonal Variations: Although the overall climate was warm, there was likely some seasonal variation, with cooler periods in higher latitudes.
* High Oxygen Levels: The atmosphere during the Carboniferous period had much higher oxygen levels than today, possibly exceeding 35%. This contributed to the gigantism seen in some insects and amphibians.
Life:
* Giant Insects: The high oxygen levels supported the evolution of giant insects, including dragonflies with wingspans of over 70 cm (28 inches).
* Amphibians: Amphibians were diverse and abundant, including early tetrapods and large amphibians like the famous *Eryops*.
* Early Reptiles: Early reptiles, like the *Hylonomus*, started to appear and were adapted to the drier conditions of the more inland areas.
* Diverse Flora: As mentioned before, the swamps and wetlands teemed with diverse flora, including large, tree-like ferns, horsetails, and lycopods.
In summary, the Carboniferous Earth was a world of giant swamps, vast forests, and a humid, warm climate. This environment supported a remarkable diversity of life, including giant insects, large amphibians, and the first reptiles.
