Geologic Time - Devonian Period

Devonian Period
Devonian Period started 417 million years ago and ended 354 million years ago. This period was the age of fish. During this period there was a sharks, rays, lobe finned fish. Ammonities increased in population. First forests formed in this period. Some trees developed up to 38m high. Some rock types were Hunsruck Shale, Rhynie Chert, and the gilboa forest. 


Project Reflection
     1. What did you enjoy most about this project?
One thing I enjoyed about this project is working in partners. So we could divide the work. 

     2. What was most challenging about this project? Why?
One challenging thing about this project was writing reference, because we had to copy every single link and paste it to our reference page. Finding information was also challenging, because you don't know which information is true and which is wrong. 

     3. What would you change about this project and why?
One thing I would change about this project is I would choose a different geologic time period.   

     4. What are the three things that you learned from this project? 
Three things I learned from this project are Earth has a huge history, and it includes eons, eras, periods, and epochs. Devonian period is one of those periods, and it is the age of fish. Supercontinent Pangea formed during this period.
