Stethacanthus

I am also not sure if this is correct.

To help study for the time periods videos, here are some of the major things that happened in the Carboniferous Period:
- The Carboniferous Period is divided in two: The Mississippian and the Pennsylvanian.
`
- The Carboniferous lasted from about 354-290 mya
`
- Many things made their first appearance in the carboniferous:
- On land:
- One of the most important events in the Carboniferous period was the creation of the amniote egg. The amniote egg is what modern day birds and reptiles use. The egg allowed animals to venture further inland because they didn't have to lay their eggs in the water (like amphibians and fish).
- There was one smaller extinction that mostly consisted of marine invertebrates which was due to climate changes caused by glaciers.

- Many things made their first appearance in the carboniferous:
1. First reptiles
2. First spiders
3. First amphibians
4. First conifers
5. First synapsids
- In the oceans:1. Giant fish with jaws ruled
2. The shark family was very prominent,
one shark being the Stethacanthus
3. Ammonites were very common
- On land:
1. Giant insects flourished because the atmosphere had
much more oxygen than it does today
2. Amphibians were venturing onto land
3. Large reptiles that were more than 2 meters long ruled the land.

I also think during this time was when coal depositing plants were present. Due to the warm climate they were able to form the coal we now use today.
