  1. Pennsylvanian Period By: Ryan Erickson 6th Hour

  2. Relation To The State ? • The period is related to the state of Pennsylvania • It is named after the coal deposits in Pennsylvania that formed during the period

  3. Date of Pennsylvanian Period • 318 MYA-299 MYA • Late part of Carboniferous Period (359 MYA – 299 MYA)

  4. Continental Position/Activity • Laurussia (North America and Europe) and Siberia formed Laurasia • Parts of Gondwana (southern supercontinent) drifted north • Pangaea (single supercontinent) was starting to form at the end of Pennsylvanian Period (299 MYA)

  5. Climate and Vegetation • Ice covered most of Southern Hemisphere (Gondwana) from Karoo Ice Age (360 MYA – 260 MYA) • Large tropical swamps formed near equator • The organic matter from these swamps formed the period’s well-known coal deposits over millions of years

  6. Atmosphere • The large tropical swamps created a surplus of oxygen (from photosynthesis – taking in carbon dioxide and returning oxygen) • Atmospheric oxygen levels reached 35% (some of the highest in all of history)

  7. Immense Insects • The astronomical atmospheric oxygen levels of the period created some of the largest insects in history Meganeura Arthropleura

  8. Immense Insects (continued) • Meganeura • Massive insect resembling a dragonfly • Could have wingspan of 70 cm (27.56 in) • Carnivores (ate insects) • Arthropleura • Massive arthropod resembling a millipede • Could be 2 meters in length (80 in.) • Herbivores (had mouthparts for eating • and chewing plants)

  9. Reptiles • The first reptiles appeared during the Pennsylvanian Period • One of the first reptiles was the hylonomuslyelli • Hylonomuslyelli • The earliest known reptile • Lizard-like • Carnivores (feed on millipedes and insects) • 20 cm (8 in.) long including tail
