Travel back in the geologic time period of choice from the Phanerozoic Eon (e.g. Cambrian, Ordovician, Permian, Triassic, Cretaceous, Neogene, Quaternary). See the Geologic Time Scale posted in the Overview for this module.

Travel back in the geologic time period of choice from the Phanerozoic Eon (e.g. Cambrian, Ordovician, Permian, Triassic, Cretaceous, Neogene, Quaternary). See the Geologic Time Scale posted in the Overview for this module. Do some research and then answer the following questions in a narrative format to help inform the class about this period. Optional – you may choose to be creative and write this as a first-person account as though you were able to travel back in time and witness this for yourself.   

1. Name the Period that you traveled to.
2. How long ago was this Period of geologic time, and how long did it last?
3. What is this Period known for?
4. What significant events took place during this Period?
5. What were some examples of plant and/or animal life during this period?
6. Keeping in mind that the current atmospheric concentration of CO₂ is roughly 400ppm (or 0.040%), what is known about the CO₂ concentration on the planet at that time? Was it higher or lower than now?
7. Was there a mass extinction event associated with the beginning or end of this Period?  Explain.
8. Include one or more images that relate to the interval of geologic time that you are writing about. 
9. Include links to the Internet resources and/or images you used.
10. Use a catchy title to headline your assignment.
